"What can be robbed tonight?" "I want to grab spicy chicken and Hengdu steak!" "Seconds kill, seconds kill, I’m waiting for seconds kill" … At 8 o’clock last night, the second season of Chongqing’s "Double Sun" entered Fengdu time. Luocheng, the county magistrate of Fengdu County, went into the live broadcast room to watch "abundant scenery" and buy "abundant things" with netizens, and felt the local landscape tour, cultural tour and food tour together.

During the live broadcast of one and a half hours, more than 310,000 netizens poured into the live broadcast room, and received 1.78 million praises. The spicy chicken was sold out of stock, and 6,000 copies were temporarily sold. Tickets for 1 yuan were sold out in two minutes … Netizens not only saw all the cultural beauty of Fengdu in the "double sun" live broadcast room, but also grabbed their favorite Fengdu specialties.

"small search for abundance"

Fengdu fans have a new name.

Just at 8 o’clock in the evening, many netizens flooded into the live broadcast room. "Fengdu Ghost Town is so famous that I want to see it." "Fengdu Temple Fair is fun, but it’s a pity that I only looked at it online this year. Will it be done next year?" "It’s hot this summer, is there a holiday package in Nantianhu Scenic Area, can it be cheaper?" … With the beautiful scenery of Fengdu gradually appearing on the screen, the audience in the live broadcast room is also growing rapidly.

Seeing the enthusiasm of netizens, Luo became a netizen who loved Fengdu and took a nickname-"Xiaomifeng". Luo Cheng said that today’s young people have their own exclusive titles. In the next 90 minutes of live broadcast, he will lead the "Little Mifeng" to experience Fengdu’s cultural experience tour, recreational holiday tour and happy and passionate tour.

Only half an hour after the broadcast, the Fengdu live broadcast room attracted more than 50,000 people to watch, with more than 830,000 likes. The whole live broadcast was watched by more than 310,000 people, and the number of likes reached 1.785 million, which was enough to see the enthusiasm of the "Little Yufeng".

2 minutes

1000 tickets for 1 yuan were robbed.

Where is the first stop to travel to Fengdu? Many people’s answer must be the famous mountain scenic spot. In the live broadcast room, Fengdu Mountain Scenic Area also took the lead in making its debut.

Luo Cheng introduced that Fengdu Famous Mountain is the first batch of national-level scenic spots and the first batch of 4A-level scenic spots in China. It is famous all over the world for its unique culture and has become a window to show the mysterious oriental culture to the world.

Since it is a live broadcast with goods, Luo Cheng has also brought real discounts to the "Little Mifeng". The original price is 90 yuan/Zhang’s ticket to Fengdu Famous Mountain Scenic Area, and the live broadcast room only needs 20 yuan/Zhang.

What’s more exciting is that the live broadcast room has also opened a limited spike in tickets in 1 yuan. With McCullough’s "putting on the shelves", netizens started a crazy snapping mode. In just 2 minutes, 1,000 tickets for 1 yuan spike were all robbed.

It is not only the scenic spot tickets that have been robbed, but also the popular Fengdu cuisine "Spicy Chicken". After visiting famous mountains, spicy chicken is also called "yet we called and urged a thousand times before she started toward us". The original price of spicy chicken in 79 yuan/bag, as long as the price of the live room is 58 yuan/bag, all of them will be robbed by netizens in five minutes. Luo Cheng discussed with the manufacturer on the spot and temporarily added 6,000 items to meet the "hands-on desire" of netizens.

The county magistrate went down to the kitchen to fry steak for netizens.

In the live broadcast room, Luo Cheng, the county magistrate, not only introduced the products to the "Xiaomifeng", but also put on an apron to show his talents and shared his experience in frying steak with you.

"Luo county magistrate, I’m Xiao Bai in the kitchen. Do you have any skills for frying steak?" The anchor who is not very good at cooking asked. Luo Cheng replied, "Don’t worry, just buy Hengdu beef."

Why is Hengdu beef so delicious? Luo Cheng introduced that beef is delicious, first of all, it depends on the variety of cattle. Hengdu beef cattle are young bulls of about 2 years old, such as Simmental and Angus. Feeding them with grain for 6-8 months will make the cows have better nutrition, richer protein and more uniform muscle fat. At the same time, during the slaughtering process, the acid was discharged at low temperature for 72 hours, so that lactic acid in the meat was naturally decomposed into water, carbon dioxide and alcohol, and adenosine triphosphate in the meat was decomposed into inosinic acid, which is chicken essence, so the taste was fresher.

McCullough explained, while dealing with the thawed steak. "I often fry steaks for my family at home, but I still have some experience." Luo Cheng said that the first step in frying steak at home is to soak up the water on the beef surface with kitchen paper after the steak is thawed and softened, and then sprinkle coarse salt and black pepper on both sides of the steak.

After "massaging" the steak with seasoning, McCullough poured olive oil into the frying pan. "My experience is that the oil temperature must be high enough before the steak is served, so that the moisture in the steak can be better locked." Luo Cheng said that after frying one side for one minute, you should first fry the sides of the steak and seal the edges, then fry the second side for about one minute. You should not fry it too hard, and finally use a little butter and rosemary before taking out the pot.

In the live broadcast room, Luo Cheng also brought the benefits of Hengdu Steak to netizens. The original price of 399 yuan/bag of Hengdu steak is 10-piece package, and the live room is only 149 yuan, and 12 packages of steak sauce, a pair of knives and forks, a steak frying pan and 2 pieces of 100 grams of whole-cut steak are also presented. It doesn’t matter if you don’t have time to snap it up. You can enjoy the special price of 149 yuan/bag within 15 days after the live broadcast.

Fengdu Kangyang Resort Holiday Room

Furnace Chongqing’s summer is coming. Have you decided where to spend the summer? In the "double sun" live broadcast room of Fengdu, Luo Chenggong brought the coolness of Fengdu to netizens.

Chongqing summer vacation, Nantianhu tourist resort is one that has to be mentioned. In the live broadcast room, Luo became a netizen to send benefits: the original price was 5680 yuan/room/month for the Minghu Resort Hotel suite, and the live broadcast room was limited to 2 sets of 1888 yuan/room/month and 3 sets of 2888 yuan/room/month. At the same time, five sets of 3888 yuan/room/month discount will be provided within 15 days after the live broadcast. Due to the large discount and scarce quantity, holiday products are all seconds.

In addition to Nantianhu, Luo Cheng, the county magistrate, also introduced Xueyu Mountain, another rural summer resort in Fengdu, to netizens. "Many people on Xueyushan Mountain are citizens from the main city, and they have become Xinfengdu people." Luo Cheng sent an invitation to more netizens in the live broadcast, inviting everyone to go to Fengdu to be a "mountaineer".

In the live broadcast room, the original price of Xueyushan Kangyang Holiday Room is 2,500 yuan/person/month. During the live broadcast, the price is only 1,200 yuan/person/month, including not only accommodation, but also three meals a day.

Wenchuang is popular.

Ghost face painting and straw painting

"Double exposure" involves exposure to "cultural and creative products" as well as "cultural and creative products".

What kind of experience is it to draw a face on a wooden ladle? "This is a unique art born out of Fengdu folk culture." Luo Cheng said that the ghost face painting is similar to the face painting of Peking Opera and Sichuan Opera, and it was awarded as "one of the best folk arts in China" in 1994. Luo Cheng invited Lei Xiaobin, the non-genetic inheritor of "Ghost Town Painting", to the scene to show netizens the production process of ghost face painting. In addition, Fengdu straw painting, a municipal intangible cultural heritage in Chongqing, was also displayed on the spot.

In the studio, the original 360 yuan/piece ghost face painting only needs 220 yuan/piece, and the original 150 yuan/piece wheat straw sculpture painting only needs 45 yuan/piece.

Because the production is not easy, there are only five products for sale on the spot, and netizens have left messages saying that "the gourd painting seeks to increase the quantity" and "is there any straw painting? How can it be used every second?" If you also like Fengdu’s cultural and creative products, you may wish to go to the local area and talk with the craftsmen about the story behind Wenchuang.

Gates: He saved more lives than any scientist in the 20th century, but Fauci said that he was also unknown in the scientific community.

Originality brings science home.

Seven kings of writing articles

In 2016, Bill Gates once commented on a person: He may have saved more lives than any scientist in the 20th century. And Fauci said that this person is also unknown in the scientific community.

Saved so many people but didn’t become famous. This person is Maurice Hilleman.

Maurice Hilleman Image source: nfid.org

Hillemann developed more than 40 kinds of vaccines in his life, and now he invented 8 of the 14 kinds of conventional vaccines for children. He is also the first person in the world who successfully predicted and stopped the pandemic of infectious diseases.

It is estimated that the vaccine developed in Hillemann saves 8 million lives every year. It is no exaggeration to say that he is the guardian of your life and mine. Today, let’s take a look at this hero who does not strive for fame and success.

Hillerman was born on August 40, 1919, the eighth child in his family. Shortly after his birth, his mother and twin sister also passed away. Later, he was adopted to a childless uncle family. Uncle Bichler Mann’s biological father is more enlightened, so he has more opportunities to explore and expand his hobbies.

Childhood Hillemann Image Source: hillemanfilm.com

It is such a child who is interested in Darwin’s theory of evolution. Because of his poor family, he almost didn’t go to college. After graduating from high school, he got a job at J. C. Penney, and he planned to spend his life like this. Fortunately, his eldest brother mediated and helped him get a scholarship from Montana State University. In 1941, he graduated from the school with the first grade.

Then he went to the University of Chicago to study for a doctorate. During his PhD, he studied chlamydia, the pathogen of a common sexually transmitted disease.

In the 1940s, the medical community generally classified chlamydia as a virus. However, Hillemann discovered through research that Chlamydia trachomatis is a special kind of bacteria. Chlamydia trachomatis can only live in cells and is a parasitic bacterium.

Chlamydia trachomatis (brown) Image source: wikipedia

Since it is caused by bacteria, chlamydia can be treated with antibiotics. This is the first city captured by Hillemann for human health.

After obtaining his doctorate, he did not stay in academia, but entered a pharmaceutical company called E.R. Squibb & Sons and began to develop vaccines.

He quickly developed his first vaccine: Japanese encephalitis vaccine. Most encephalitis is caused by Japanese encephalitis virus. After being infected by Japanese encephalitis virus, the patient’s brain swells and the mortality rate is high. During World War II, the Japanese encephalitis vaccine developed by Hillemann was used to immunize the US military.

Japanese encephalitis virus is transmitted by mosquitoes.

In 1949, Hillemann became the chief scientist of respiratory diseases in The Walter Reed Army Institute of Research, when he began to study influenza virus.

During this period, he made several important discoveries about influenza virus. He pointed out to the world for the first time that the spike protein on the surface of influenza virus will change, avoiding the recognition of immune system. Everyone should have heard of spike protein. This year, the COVID-19 vaccine jointly developed by German pharmaceutical company BioNTech and Pfizer was immunized by training human immune system to recognize spike protein on the surface of Covid-19.

Later, biologists called this change of virus antigenic drift, and the major variation was called antigenic shift.

Antigenic transformation often leads to epidemic outbreaks, because few people in the world are immune to the new virus after the virus mutates.

In order to achieve antigenic transformation, the influenza virus that infects people needs two tool animals: birds and pigs. Pigs can be infected by both avian influenza virus and human influenza virus. Therefore, the two viruses can communicate in pigs to form a new and stronger influenza virus.

Hillemann’s discovery explains why the flu vaccine developed by the US military usually fails in the second year, and also helps him save millions of lives.

On April 17th, 1957, The New York Times reported the news of a large-scale influenza outbreak in Hongkong. Many Americans don’t think this is a disaster in a foreign country, and it has nothing to do with themselves. But Hillemann was keenly aware that the news was not simple.

During the Asian flu in July 1968, patients waiting for treatment in a clinic in Hong Kong. Image source: SCMP

The day after reading this report, he sent a telegram to an army medical general laboratory in Zama, Japan, and obtained the saliva of an infected American soldier.

After studying the patient’s saliva, Hillemann found that only a small group of old people who had experienced the "Russian influenza" pandemics in 1889 and 1890 had immunity, while younger people had no resistance to the new influenza virus.

Hillemann realized that the global influenza pandemic had arrived, and began to actively promote the development of influenza vaccine before the start of school in autumn.

In September 1957, an epidemic named the Asian flu entered the United States. However, at that time, the United States had produced and distributed 40 million doses of influenza vaccine, and the research and development time of the vaccine was only four months.

This is the attendance of a primary school in Tokyo when the Asian flu broke out at that time.

In the end, this virus (Type A2) called "Asian Influenza" caused about 70,000 deaths in the United States. But in 1957-1958, the virus caused about 2 million deaths worldwide.

Leonard Burney, then director of the US Department of Health, said that without this vaccine, millions of people in the United States would have died of the flu.

In this way, Hillemann became the first person in history to accurately predict the pandemic. Because of this incident, Hillemann was awarded the Distinguished Service Medal by the US military.

At the end of 1957, Hillemann began to work for Merck Pharmaceuticals and stayed there until he retired. At Merck, he developed vaccines against chickenpox, hepatitis A, hepatitis B, streptococcus pneumoniae, meningococcus, measles, mumps and rubella.

Mumps often leads to deafness. Image source: wikipedia

Hillemann was also the first person to integrate antiviral vaccines. With the triple vaccine against measles, mumps and rubella, children can gain immunity to measles, mumps and rubella only once.

Mumps vaccine has reduced the number of patients in the United States from 200,000 to 200 every year. The World Health Organization estimates that measles vaccine alone prevented 20.3 million deaths worldwide from 2000 to 2015.

There is another interesting story when it comes to the measles-mumps triple vaccine.

In fact, the virus used to make mumps vaccine was extracted from his adopted daughter Jeryl Lynn. Until now, the virus strain from his daughter is still being used to make mumps vaccine, and this virus strain is also named Jeryl Lynn strain.

Hillemann’s last invention-hepatitis B vaccine also made him the first person to fight cancer-liver cancer with a vaccine.

Hepatitis B virus is a major pathogen of liver cancer, the third largest cancer in the world. According to Baruch Blumberg, the Nobel Prize winner in 1976, there are about 375 million people in the world who are carriers of hepatitis B virus, and they are all at risk of liver cancer.

In order to develop hepatitis B vaccine, Hillemann did a very dangerous thing-purified hepatitis B surface antigen (HBsAg) from the blood of patients with hepatitis B and made hepatitis B vaccine.

Schematic diagram of hepatitis B surface antigen (purple)

There are two reasons why this matter is dangerous: First, in the process of research, hepatitis B virus may infect researchers.

Secondly, who wants to try a vaccine made of patient plasma at the cost of his life? After all, the protein of hepatitis B surface antigen is what hepatitis B virus does in human body to avoid the attack of immune system. Many people without medical background are afraid that they may be infected with hepatitis B after being injected with this protein.

In order to prove the effectiveness and safety of the vaccine, Hillemann personally went into battle and injected hepatitis B vaccine under the watchful eye of everyone.

However, because a new deadly disease, AIDS, appeared in the 1980s, many people were afraid that the hepatitis B vaccine purified from plasma might also carry the pathogen of AIDS, so the first generation of hepatitis B vaccine was in trouble.

However, Hillemann’s team soon found a way to make hepatitis B vaccine without human plasma. In 1986, they used gene technology to successfully make yeast produce HBsAg.

This vaccine is now used in 150 countries around the world. By 2003, the number of young hepatitis B patients in the United States had dropped by 95% compared with before the emergence of vaccines. Hepatitis B vaccine may be the medical product that saved the most people in the 20th century.

Hillemann believes that hepatitis B vaccine is the most important job in his life. Thomas Studds, a pioneer of liver transplantation, praised hepatitis B vaccine as "one of the greatest contributions to medicine in the 20th century. Hillemann has removed the biggest obstacle in the field of organ transplantation. "

After retirement, Hillemann became a consultant of the World Health Organization. In 1988, President Reagan awarded him the National Medal of Science award, the highest honor in American science.

Although many people’s lives depend on him, few people outside the circle know his name and he didn’t win the Nobel Prize.

Robert Gallo, the co-discoverer of HIV virus, the pathogen of AIDS, once said: "If you want to name a person who has made great contributions to human health, but has not received due recognition, this person is Hillemann."

Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, even said: "Even in the scientific community, few people know how much Morris has contributed. I recently asked my postdoctoral fellow if he knew who developed measles, mumps, rubella, hepatitis B and chickenpox vaccines. They said they didn’t know. "

Hillemann didn’t go out of the circle because of his low profile. Hillemann didn’t sign a paper to prove the effectiveness of hepatitis B vaccine, nor did he name any vaccine with his own name.

Hillemann seems to be the embodiment of human immune system. A healthy human body can’t benefit from the immune system, but TA has been silently protecting you in an invisible place.

Hillemann saved the most people in the 20th century, and some people’s hard disks saved the most people in the 21st century.

Greet the future with a smile.

  It is our happiest moment to send the recovered patients out of the hospital.

  Xing Zhengtao, member of xuanwu hospital Aid Hubei Medical Team of Capital Medical University.

  On March 15th, the west courtyard of Union Medical College Hospital affiliated to Huazhong University of Science and Technology turned cloudy.

  At the time of the rapid development of the epidemic, in order to ensure that all the "four types of personnel" should be treated, Wuhan has expanded a number of hospitals and designated medical points, and many hospitals have also added beds in time. At that time, what we experienced was that we were adding wards and accepting new patients every day.

  The intensity of work in the isolation ward is more tiring than that in the emergency room, but I am willing to go into battle! I decided to choose a nursing major to help more people in need because I saw how helpless my family was when they were sick.

  Compared with the previous work rhythm of "walking with the wind" and "saving lives" in the emergency department, the work in the isolation ward needs to be more cautious. Walk lightly, walking fast will bring the virus; Also be careful not to rub it elsewhere, and the protective clothing may be scratched. With my strong figure, I dare not sit, let alone squat. I will open my crotch when I squat down my protective clothing.

  It is more difficult than ensuring that the movements are light and small, and the medical staff should "run at high speed" on this basis. In the first few days of working in the ward, many nurses were flustered and so on. My heart rate has also reached more than 100 times per minute, just like after running, the protective clothing is very uncomfortable, and there is always some wheezing.

  Now, I have been working in Wuhan for more than 40 days. With the improvement of the situation, the workflow has become smoother. From "saving lives in a hurry" to "doing my work in detail", my work content has also changed, among which, caring for patients accounts for a large part. Because anxiety is a common emotion of these diagnosed patients.

  Wearing protective equipment, patients can’t see the mouth shape and smile of medical staff. But perhaps to visit the patient more, say "hello" and send a glass of water are all respect and encouragement for the patient.

  Gestures, eyes and words have become the ways to convey encouragement and increase confidence in special circumstances. What I often say these days is "Let’s just get through this time, come on". When I meet a patient with poor hearing, I have to shout and then make a gesture of refueling.

  There is a patient in his fifties who is impatient. The oxygen mask makes him feel uncomfortable. He always unconsciously takes off his mask. So when I was on duty, I went to run, advised and tried my best to take care of the patients with the greatest love. Some patients talk to us with their backs to us in order to reduce the risk of infection of medical staff. I am deeply moved by such "small actions" of patients.

  From life to nursing, from pathological explanation to psychological support, my colleagues and I are never afraid of being tired. It is our happiest moment to send the recovered patients out of the hospital.

  Difficult, you have to meet the difficulties to become the best soldier. Every time I take off my protective clothing, I’m almost happy to get a new life. Now I will cherish the day when I take off my protective clothes and masks. I hope the epidemic will end soon! Let everyone breathe freely! Victory is coming soon, keep on cheering!

  Please wait for me.

  On March 14th, tongji hospital Guanggu Campus affiliated to Huazhong University of Science and Technology was sunny.

  March 14th, sunny, night off. Today is white day, and it is a festival to give gifts to men. I remember a month ago on Valentine’s Day, my family recorded a video for me for more than a dozen times, which was really tireless. Today, I also have something I want him to say.

  Brother David:

  I still remember that when I learned that our hospital had the task of rushing to help Wuhan, I sent a message to the director of nursing department. To be honest, I was quite nervous at that time, but the director of nursing department affirmed and encouraged me, which made me less nervous. I didn’t tell you after I signed up. I was afraid you were worried, but I wanted to do my part very much. I always felt that there was a voice calling me. You didn’t know I signed up until the director of nursing department called me to confirm and verify. You are silent, I know you love me. On the night of February 8, I received the news that I was leaving for Wuhan the next day. You and I stayed up all night, and my daughter woke up from a dream several times. I know that you don’t want me to leave. I will never forget that scene. When the car started, you beat the window and cried and said to me, "You must come back safely."

  You have always liked poetry and originality, and you will write poetry to me after your daughter falls asleep. Friends all said, "Fortunately, taking care of the baby alone didn’t kill the poetry."

  We won’t go offline until the epidemic is over, so please wait for me. Thank you for your support. I’ll give you a big hug when I get back.

  Smile is like the sun warming people’s hearts.

  Nurse of Deng Tianxing Nuclear Industry General Hospital (Second Affiliated Hospital of Soochow University)

  On March 14th, Wuhan Union Medical College Jiangnan Hospital was sunny.

  It’s been 47 days since I arrived in Wuhan, and now it’s clear in Wan Li. Looking at such fine weather, I really want to go out for a spring outing. As usual, I put on protective equipment and came to the ward. After the shift, I visited the ward and found that there were two old people living in this room. My grandmother waved to me. I pushed open the door and went to my grandmother’s bed. My grandmother frowned and told me that I had just finished lunch, but the rice was too hard to swallow, so I didn’t eat it. Now my stomach hurts badly.

  When grandma finished speaking, I realized that I must be hungry, so I quickly went to the nurse’s station to deliver the eight-treasure porridge that I had brought to the ward, and gave it to grandma with hot water. Grandma said thank you while eating, and showed a kind smile. This kind of smile is like the sun today, which warms the heart.

  In the afternoon, when it was time for rehydration, I pushed the treatment cart to an old man’s bedside and began to evaluate the puncture site after careful checking. The old man gave me his hand very well, and when he saw that his hand was full of "needle holes", he felt sad. Grandpa smiled and told me that my hand was not easy to hit, so you couldn’t wait. I carefully searched for a suitable puncture site and finally found a vein suitable for puncture. After disinfection, I told my grandfather that I started to puncture, which was a little painful.

  People who love to laugh will always warm the people around them. Let’s greet the future with a smile!

  No doctor can cure diseases, but companionship can heal the heart.

  March, a spring breeze, a season of blooming flowers! The dawn of the war epidemic has come, but the allergic rhinitis that followed has also come.

  In the busy work, I have long forgotten that I am allergic every March. Until these two days, my eyes have been itching badly and I have a runny nose. I suddenly realized that it was over, and allergic rhinitis was committed. I quickly ate kairuitan, trying to relieve the symptoms, but it didn’t help. Every day, my eyes are extremely itchy. I always want to rub them with my hands. Do you know what my allergic rhinitis patient looks like after wearing protective clothing? The fog in the goggles makes the eyes itch more; On weekdays, we all breathe with our mouths open in protective clothing, and we dare not open our mouths too much for fear that nose will flow in. It is really embarrassing to insist on not wiping or touching for four hours in polluted areas. However, watching patients get better day by day, all difficulties can be overcome. "You" are my hope and my motivation!

  In fact, no matter what you do, you will encounter difficulties, and you must face them to become the best soldier. Every time I take off my protective clothing, I’m almost happy to get a new life. Now I will cherish the day when I take off my protective clothes and masks. I hope the epidemic will end soon! Let everyone breathe freely!

  Avoid infection. I have these little details of my life

  Tang Huijuan, Nurse in Charge of 416 Hospital of Nuclear Industry

  March 13th The Cancer Center of Union Medical College Hospital affiliated to Huazhong University of Science and Technology was sunny.

  It’s just one month since I helped Han. Although it’s cold, my heart is warm. The support and guarantee from hospital leaders, teachers, colleagues, classmates, team leaders and logistics here have made us feel extremely at ease. I am very happy and live in a United and friendly country. I should use my knowledge to give back to every Wuhan people, take good care of every patient at work, and wish to be a big sister in life and spend this difficult time with everyone.

  To avoid infection when coming to Wuhan, the requirements of hospital feeling are very high. Here, I share some small details of my life.

  Every time we go from the hospital to the hotel, how can we protect our sense of hospital?

  First of all, outside the hotel, you wear a mask. When you enter the room, you need to breathe freely. Therefore, shoes and clothes returned from the hospital are placed at the door of the room, cleaned regularly and kept clean and disinfected. Shoes must strengthen the cleaning and disinfection of soles; After hand disinfection, remove the mask and hat and fasten it with a pocket.

  If the hands are contaminated, disinfect them in time, take off the clothes outside, enter the room and wear sandals prepared in front of the door, soak the clothes in vats and chlorine-containing disinfectants and cover them; Then enter the bathroom, release the water with a stain-proof paper, and immediately carry out the seven-step washing method.

  When taking a bath, pay attention to cleaning the ear canal, nose, etc., and pay attention to the division of room areas, which cannot be crossed. Shoes in semi-polluted areas cannot go to clean living areas. Shoes in the clean area can only be in the clean area, not in the semi-polluted area.

  I was also divided into three parts in the bathroom. When I came back from the hospital, I must go to Area 2 to wash my hands, including washing clothes from the hospital. After bathing, the bathing area must be cleaned and disinfected. Washing hands and clothes in daily life must be in area 1. Do not cross each other. After use, you can wash the sewer with boiled water and keep it dry to avoid bacterial growth.

  It’s very cold in Wuhan. I brought three down jackets. I wore a soft one to sleep. I brought a cup to warm the bed. I dug a hole in the breakfast box as a soap box, so as to avoid the growth of soap and bacteria. I put up curtains all the time to avoid dust, and the windows are always open for ventilation. I wipe the floor with a wet rag during rest and keep it clean. Everything is just to reduce the chance of infection and make myself feel at ease.

Focus on "New Infrastructure" | Big Data Center will become a new connotation of national competitiveness.

Sun Huifeng: He is currently the president of CCID Consulting Co., Ltd., a special expert of the Operation Monitoring Coordination Bureau of the Ministry of Industry and Information Technology, deputy secretary-general of China Computer Industry Association, a special expert of the Management Advisory Committee of China Entrepreneurs Association, and an adjunct professor of Beijing Jiaotong University.

The new infrastructure construction refers to the infrastructure construction focused on science and technology, which mainly includes seven major fields, such as 5G infrastructure, UHV, intercity high-speed railway and intercity rail transit, new energy vehicle charging piles, big data center, artificial intelligence and industrial Internet. The construction of new infrastructure is mainly manifested in digitalization and intelligence, and its core is to provide the underlying support for the development of intelligent economy and the digital transformation of industry.

1. Why are big data centers shortlisted for new infrastructure?

1, the underlying infrastructure of intelligent economy

With the surge of digitalization, our production, life and everything are being defined by numbers. Everyone, everything, every transaction and every activity can be labeled with specific numbers, and even our thinking can be transformed into digital information to be expressed. Twenty years ago, the growth rate of data was only about 100GB per day, but now, the growth rate of data has reached about 5TB per second. There is no data, no data, no calculation, no data without truth. The data explosion and data value generated by digital application will inevitably bring demand for information infrastructure. The scale and quality of information infrastructure construction will directly determine the speed and height of economic development in the current digital economy era. It can be said that developing information infrastructure is the general trend and the inevitable path.

2. The inevitable trend of industrial digital transformation.

Digital economy has become the main line of global economic development. The key to the development of digital economy is to promote the penetration of digital technology in various industries, give birth to new industries, new models and new formats, and release the vitality of industrial economy. Industry digitalization not only has higher requirements for the ability of perception, transmission, storage and processing of data and information, but also includes the increasing demand for digital platforms, big data platforms and cloud infrastructure platforms, and it also needs to build a digital ecology of the whole value chain. All means of realization cannot be achieved without the support of information infrastructure, without calculation and transformation. The inherent requirements of industry digitalization and intelligent transformation need to be promoted by developing information infrastructure.

3. The concentrated expression of the new connotation of national competitiveness.

Computing power is the concentrated expression of a country’s future competitiveness. From new materials and new energy development to high-end equipment simulation design, biological genes, intelligent transportation, emergency security and many other fields, scientific and technological innovation needs "computing power" as the foundation; Similarly, the development of the new economy requires the integration of new technologies such as big data, cloud computing and artificial intelligence with the real economy, the reconstruction of industrial ecology, and the birth of new models and contents. The power behind it is also the development of information infrastructure and the landing of new technology application scenarios. The outbreak of this epidemic has spawned a series of new formats and models, including online training, online prevention and control, distance education and telemedicine. It also shows that the combination of "cloud and digital" is an important force supporting business model innovation. Computing power is power. Enterprises or countries with super computing power will have the opportunity to integrate industrial resources, build industrial ecology and cultivate competitive advantages. Therefore, they will have the supreme power to dominate the distribution of industrial value.

Second, the global and domestic development of big data centers

1. The construction of digital economy has entered a large-scale implementation period, and the investment in data centers has increased steadily.

Next-generation information technologies, such as cloud computing, big data, Internet of Things and artificial intelligence, have developed rapidly, and data has exploded, so the construction of data centers has become the general trend. Major countries and enterprises in the world have started the road of digital transformation. Driven by this upsurge, IT investment in global data centers has shown a rapid growth trend. The growth rate of IT investment in data centers around the world and China is higher than that of global GDP (2.3%) and China GDP (6.1%).

2. The Asia-Pacific market is still the highlight of the global data center market, with the fastest investment growth.

From the perspective of global data center construction and development, the IT investment scale of data centers in the world’s top three data center markets-the United States, Japan and Europe still accounts for more than 60% of the global data center IT investment scale. The United States maintains its market leadership position and leads the global data center market in terms of data center products, technologies and standards. The Asia-Pacific market is still the highlight of the global data center market, with an increase of 12.3% compared with the same period in 2018, and the IT investment scale of data centers reached 75.17 billion US dollars. The main driving force still comes from the steady development of the data center market in China, the deepening of applications such as mobile Internet, cloud computing, big data and artificial intelligence, and the acceleration of the construction of industrial Internet in internet plus.

3. The number of data centers has slowed down, and the proportion of large data centers has increased year by year.

According to the connotation of the concept of data center and the industry’s unified understanding of the characteristics of data center, CCID Consulting defines a data center as a place that is built according to unified standards and provides a stable and reliable operating environment for centralized IT application systems with computing power, storage capacity and information interaction capability. Data centers can be divided into enterprise data centers (EDC) and Internet data centers (IDC) according to the service objects. An enterprise data center refers to a data center built and owned by an enterprise or institution to serve its own business. Internet data center is owned by IDC service provider and provides paid information services to customers through the Internet. At the same time, we also give the definition of data center type according to the rack size.

In 2019, there are about 74,000 data centers in China, accounting for about 23% of the total data centers in the world, with 2.27 million data center racks and 2,213 IDC data centers in use. The trend of large-scale and large-scale data centers continues, and regional applications and multi-level group enterprises tend to avoid blind construction and repeated investment through large-scale construction. In 2019, the number of super-large and large data centers reached 12.7%, and 320 data centers were planned to be built, accounting for 36.1%. Compared with the United States, there is still a big gap in this data. American super-large data centers have accounted for 40% of the global total, and there is still much room for development of large data centers.

Third, the future growth potential and driving factors

1. Data resources have become a key factor of production and a "new energy" for the development of digital economy.

With the rapid development of Internet, everything is digitized, and the amount of data and calculation explodes exponentially. According to CCID Consulting’s data, by 2030, the original data production industry will account for 15% of the total economic output, and the total data in China will exceed 4YB, accounting for 30% of the global data. Data resources have become key production factors, and more industries extract valuable information by using structured or unstructured data resources such as Internet of Things, industrial Internet and e-commerce. The processing and analysis of massive data requires the construction of a big data center.

2. Scenario applications such as AI, 5G and blockchain have opened up new growth space for the development of data centers.

With the joint promotion of national policies and capital, the AI ecology has been continuously improved, and the application of AI scenarios has been accelerated. AI infrastructure services will usher in a new era of rapid development. The commercialization of 5G is just around the corner, and a large number of applications based on 5G have begun to be demonstrated and promoted in traditional industries such as finance, manufacturing, medical care, and retail. The application requirements such as VR/AR, autonomous driving, high-definition video, intelligent transportation, and intelligent medical care will also open up room for the development of data center market and the innovation of service model. At the end of 2019, the government listed the development of blockchain technology as the key direction of national strategy for the first time. In the future, the application scenarios of blockchain technology will extend from the current economic fields such as cross-border transactions, commodity traceability, financial innovation and supply chain integration to social policies and public services such as people’s livelihood needs, urban governance and government services, which will inevitably bring a large number of distributed computing, distributed storage and distributed database management needs, which are inseparable from the support of big data centers.

3. The demand for industrial computing is strong, which will become a new driving force for the development of data centers in the future.

As a product of the deep integration of the new generation of information technology and manufacturing industry, the industrial Internet has increasingly become the key support of the new industrial revolution. China has a huge application market of informationization, digitization and intelligence, and the informationization transformation, digitization and intelligent upgrade of traditional industries. In the future, the pace of enterprises going to the cloud and equipment will accelerate, and the demand for industrial computing will increase explosively. Moreover, the state attaches great importance to the development of the industrial Internet. In March 2019, the industrial Internet was written into the government work report for the first time, proposing to focus on promoting the high-quality development of the manufacturing industry, building an industrial Internet platform, expanding "smart+"and empowering the transformation and upgrading of the manufacturing industry. The deployment and development of industrial Internet applications and the demand for industrial computing services will become a new driving force for the development of data centers in the future.

Expert interview: Old viruses frequently change their faces. Traditional antivirus is in a hurry.

  New anti-virus technology for active defense


  The opening and closing ceremonies of the Beijing Olympic Games and Paralympics are the focus of the world’s attention. Assuming that the computer information of the general director Zhang Yimou is stolen and attacked by hackers, not only will the Olympic plan be leaked, but even the opening and closing ceremonies will not be able to proceed normally …


  In the US presidential election, Obama was most worried about the theft of his core computer and the attack on the network. He summed up his victory and the victory of the network.


  Network security has a bearing on the people’s livelihood. Faced with more than 1,000 new viruses appearing every hour in the world, traditional anti-virus software is increasingly lagging behind, and active anti-virus technology emerges as the times require.


  According to the 2008 National Survey Report on Information Network Security and Computer Virus Epidemic released by the Ministry of Public Security recently, among the types of network security incidents, computer viruses, worms and Trojan horses are still very prominent, accounting for 72%. Another new security risk "passive leak" is eroding the computer network.



  Liu Xu, a famous anti-virus expert and leader of the research group of "Real-time protection technology based on independent analysis and judgment of program behavior" of the National 863 Program.


  What causes the increase of "passive disclosure", and how can users avoid being victims of Trojan virus or targets of "spy" programs? The reporter interviewed Liu Xu, a famous anti-virus expert and the leader of the research group of "Real-time protection technology based on autonomous analysis and judgment of program behavior" of the National 863 Program.


  Hackers wholesale a "broiler" in 0.1 yuan.


  Zombies attack other people’s computers in groups


  Users unconsciously passively leak secrets.


  Liu Xu said that in the industry, computers controlled by hackers are called "broilers", and any computer may become a "broiler". For hackers, "broiler" has no secrets, and all information files can be easily adjusted. Such a "broiler" is now sold online only in 0.1 yuan. Because of its low price, "broiler" is generally sold in tens of thousands of wholesale units. Recently, the use of "Microsoft black screen genuine verification" to spread the variant gray pigeon new virus is to make the user’s computer a remotely controlled "broiler".


  There are even more terrible "zombies", that is, computers controlled by "zombie" viruses. These computers are aggressive, and the "zombie" computers controlled by hackers form a network, which will attack other people’s computers and important websites. "Zombies" are mostly overseas hacker networks, mainly stealing trade secrets and threatening the security of national information networks.


  Liu Xu said that the purpose of writing and making viruses has changed from "harming others without benefiting themselves" to profit-seeking attacks, such as stealing information; The computer poisoning rate also rose from 73% in 2001 to 91.47% last year. At present, viruses have the latest features such as instrumentalization and automatic generation, and at the same time, they have the characteristics of concealment, anti-killing and pertinence. Unknown viruses and new viruses make users hard to prevent. In the past two years, "online thieves", "panda burning incense", "dove", "QQ Trojan" and "zombie Trojan" have invaded users’ computers and stolen password accounts, personal privacy, business secrets, network property and even state secrets, which are typical examples. If we don’t take precautions against these Trojans and spy viruses, it will easily cause users to passively disclose information unconsciously.


  Traditional antivirus only looks for a piece of program code.


  There is nothing I can do about makeup makeovers.


  Almost all computers are equipped with anti-virus software, but why are users repeatedly attacked and even passively leaked information? Liu Xu said that the traditional anti-virus software was an effective tool in the past when the number of viruses was small and the spread speed was not fast. However, today, with the wide application of the Internet and the subversive changes in the global virus characteristics, it is obviously inadequate.


  Liu Xu analyzed the principle of traditional antivirus software. For example, traditional anti-virus software kills viruses, just like low-level security guards catch thieves, relying entirely on local characteristics. If you catch a thief in red today, you think that everyone in red is a thief, and if you catch a thief in yellow tomorrow, you think that the thief in yellow is also a thief. When a virus is found, one or several program codes are found, which is the virus feature code. Once similar or identical codes are found, it is considered as a virus. Traditional anti-virus software adopts the eigenvalue scanning technology: the idea of "virus appearance ―― user submission ―― manual analysis by manufacturers ―― software upgrade". The prevention of virus always lags behind the emergence of virus, and generally it can only kill the virus found by manufacturers, but it is helpless for new viruses or those that have undergone "cosmetic" transformation.


  At present, viruses have been automated and industrialized, and anti-virus manufacturers are still adopting backward ideas of manual analysis, which is bound to fail to prevent unknown viruses and new viruses. Realizing the transformation of anti-virus technology from passive anti-virus after the event to active defense is not only the common topic and new competition focus of the global anti-virus industry, but also the urgent demand of computer users.


  Micro-point active defense software of 863 project


  Ensure the network security of the opening and closing ceremonies of the Olympic Games


  Liu Xu said that at present, most anti-virus software claims to have active defense function, but active defense is a real-time protection technology based on independent analysis and judgment of program behavior, which must have three basic characteristics: independent identification of unknown viruses and new viruses, clear reporting and automatic removal. This is the touchstone to distinguish between true and false active defense, especially "clear reporting" of unknown viruses and new viruses, which most anti-virus software can’t do.


  In addition, some traditional anti-virus software does not explicitly report whether there is a virus, but uses some languages that ordinary users can’t read, such as: "A program is setting a global hook for your computer, is it allowed?" and "A program is loading a driver, please choose", so that users can judge for themselves, and it is difficult for non-computer professionals to choose.


  The national 863 project-micro-point active defense software is the first active defense software in the world. By using the simulated anti-virus expert and its virus determination mechanism, it has achieved the breakthrough of five core technologies, such as "dynamic simulation of anti-virus expert system, automatic and accurate determination of new viruses, simultaneous monitoring of program behavior, automatic extraction of feature values to achieve multiple protections, and visual display of monitoring information". After nearly a million kinds of viruses have been tested, the effective rate of preventing and killing unknown viruses and new viruses is over 99%.


  Since the opening and closing ceremonies of the Beijing Olympic Games, the operation center adopted the national 863 project-micro-point active defense software, which successfully prevented the attacks and intrusions of hackers and various new and old viruses, and the network information system of the operation center never leaked information, which indicates that China’s anti-virus technology has successfully withstood the major test of the Beijing Olympic Games and Paralympic Games.


  Don’t go to unhealthy websites to avoid being poisoned.


  Rejecting unknown mail is best for special plane.


  Copying files between computers without USB flash drive


  Liu Xu pointed out that users should have a conscious awareness of information security. First of all, we should develop good online habits. Some unhealthy websites are often an important reason for users’ virus infection.


  Secondly, it is not only a way to infect and spread the virus, but also an important reason for the passive disclosure of information caused by virus attacks and hacker intrusions. In practical work, especially for users with high requirements for information security, we should try our best to put an end to copying files back and forth between different users with USB flash drives, and we should also strengthen the protection of users’ own mail security and refuse unknown mail. At the same time, the conditions should be dedicated to the special plane.


  Third, adopt safe and reliable anti-virus tools. More and more examples have proved that anti-virus software itself is vulnerable to attack. Therefore, we should not only use non-genuine software with caution, but also carefully choose anti-virus tools. It is a reliable choice to adopt anti-virus tools with real active defense technology.

COVID-19 XBB trivalent vaccine is fully launched! Further build a national immune barrier.

When the weather gets cold after entering winter, it may face the risk of mutual or co-epidemic of COVID-19, influenza and other respiratory infectious diseases, which will bring a new round of respiratory infectious disease infection peak, so it is urgent to prevent it in advance.

According to the report of China CDC, since 2023, the proportion of XBB mutants and their subfamilies in China has gradually increased, reaching 99% by the end of August. XBB series mutant is a kind of recombinant mutant in Omicron, and its spreading ability and immune escape ability are stronger than those of Omicron mutant which was popular in the early stage, so it is a global dominant strain at present.

At the end of July, 2023, the State Council issued the Work Plan for Vaccination of Key Population in Covid-19 in the Near Future (hereinafter referred to as the Vaccination Plan) in response to the joint prevention and control mechanism of novel coronavirus infection. The Vaccination Plan clearly states that during the epidemic period of XBB mutant in Covid-19, especially in autumn and winter this year, it is recommended to vaccinate the vaccine containing XBB mutant antigen. The recombinant trivalent XBB Covid-19 trimer protein vaccine (Sf9 cells) developed by WEISKE Bio/Sichuan University Huaxi-VIKEXIN trivalent XBB vaccine has been officially launched in many places in China recently.

The research shows that XBB mutant has strong immune escape ability and is prone to breakthrough infection, and the key population such as the elderly population is more harmful after being infected with XBB mutant. The "Vaccination Plan" points out that people aged 60 and above who have completed basic immunization or have been infected with Covid-19, or people aged 18-59 who have serious basic diseases, people with low immune function, and people with high risk of infection (including: civil affairs, health care, education, housing construction, transportation, public security, justice, state-owned assets, finance, market, cultural tourism, industrial letter, commerce, science and technology, people and society)

In July this year, the State Council Joint Prevention and Control Mechanism promulgated the "Vaccination Plan", and the trivalent XBB vaccine of Wickham has been included in emergency use in a certain range, which can be used for vaccination of key populations in the near future. This vaccine is the world’s first broad-spectrum COVID-19 vaccine developed by West China of Sichuan University in conjunction with Wesker Biological Team to effectively prevent diseases caused by Covid-19 XBB.1.5 and other variants, and can effectively prevent diseases caused by current XBB and other variants Covid-19.

It is reported that at present, the 3-valent XBB vaccine of Wickham has been delivered, and will arrive at many CDC and inoculation units in the country one after another. Citizens who meet the inoculation conditions can consult the relevant CDC and inoculation units to make an appointment for vaccination.

Accurate and powerful, better security.

Wickham trivalent XBB vaccine is a high-purity and high-quality trivalent mutant recombinant protein vaccine produced by Wesker Bio, which takes advantage of the rapid response of the international advanced insect cell technology platform to produce recombinant protein vaccine. Aiming at the spike protein receptor binding domain (S-RBD) and heptapeptide repeat domain (HR) of COVID-19 mutants such as XBB, the vaccine is prepared by accurately designing subunit vaccine antigen based on structure, self-assembling into stable protein particles with trimer structure, purifying and mixing, and adding oil-in-water emulsion adjuvant based on squalene. The innovative adjuvant greatly improved the titer of neutralizing antibody of the vaccine, and made the trimer protein vaccine induce a stronger T cell immune response in vivo.

The clinical trial data showed that the trivalent XBB vaccine of Vikexin could induce high-level neutralizing antibodies against the mutant strains such as XBB.1, XBB.1.5, XBB.1.16, XBB.1.9.1, EG.5, XBB.2.3, BA.5, etc., with good safety, which is of great significance to prevent the infection of mutant strains and reduce the severe disease rate and mortality rate.

It is reported that since May, 2023, the World Health Organization (WHO), the US Food and Drug Administration (FDA), the European Center for Disease Control and Prevention (ECDC) and the European Medicines Agency (EMA) have successively made suggestions on updating the composition of the vaccine in COVID-19 in 2023, and proposed that the new vaccine should induce neutralizing antibody reaction against the XBB mutant, the mainstream strain in COVID-19. WHO suggests that the elderly, young people with severe complications (such as diabetes and heart disease), people with low immune function and frontline health workers should be given priority to receive COVID-19 vaccine against XBB mutant.

In September, 2023, the Centers for Disease Control and Prevention (CDC) officially updated and recommended the XBB mutant COVID-19 vaccine in the United States, suggesting that people over 6 months in the United States should be vaccinated with the upgraded COVID-19 vaccine with XBB.1.5 as antigen in autumn and winter of 2023. According to US government data, as of mid-November, about 36 million adults have been vaccinated with the latest COVID-19 vaccine, which means that 13.9% of adults have been vaccinated with the upgraded XBB COVID-19 vaccine in the two months since the XBB vaccine was launched in the United States.

Drawing a Beautiful Picture of "Agriculture, Countryside and Farmers" in the New Era —— Looking forward to the prospect of China’s agricultural and rural modernization from the perspective of rural re

In the new era, the development of agriculture, countryside and farmers stands at an important node.

In the past five years, China’s historic achievements in agriculture, countryside and farmers have attracted worldwide attention, and at the same time, it has encountered some new "growing pains". People are generally concerned: Where is the orientation of agricultural and rural modernization in China? How to get there?

Focusing on the goal of building a well-off society in an all-round way and building a socialist modernization power in an all-round way, the CPC Central Committee with the Supreme Leader as the core has made great efforts to promote the modernization of agriculture and rural areas, enhance the sense of happiness of hundreds of millions of farmers, and put forward the strategy of rural revitalization, which has pointed out a new direction and drawn a new blueprint for the development of agriculture, rural areas and farmers in the new era.

New orientation: the development of agriculture, countryside and farmers has entered a new stage, and rural revitalization shoulders a new mission.

The report of the 19th National Congress of the Communist Party of China pointed out that the issue of farmers in agriculture and rural areas is a fundamental issue related to the national economy and people’s livelihood, and we must always take solving the "three rural issues" as the top priority of the whole party’s work.

In the new era, the main contradiction in our society has been transformed into the contradiction between the people’s growing need for a better life and the unbalanced development. Looking at "agriculture, countryside and farmers" from this perspective, the achievements are impressive, but the problems cannot be avoided.

The implementation of the rural revitalization strategy is to meet the new requirements of the changes in major social contradictions-

"At present, the biggest development imbalance is the imbalance between urban and rural development; The biggest lack of development is the lack of rural development. " Minister of Agriculture Han Changfu said.

Under the new situation, the main contradiction of agriculture has changed from insufficient aggregate to structural contradiction, which is mainly manifested in the coexistence of staged oversupply and insufficient supply. Agricultural and rural development has entered a new historical stage.

Externally, the gap between urban and rural areas is still large. Ye Xingqing, Director of Rural Economic Research Department of the State Council Development Research Center, said that the east and west, cities and rural areas, regardless of economic development, infrastructure and public services, rural areas are obvious shortcomings in development.

Internally, agriculture and rural areas have entered the platform period of structural upgrading, mode transformation and power transformation, and it is urgent to cultivate new kinetic energy to adapt to the new situation.

The demand has escalated, and the effective supply can’t keep up. Li Mingfang, who lives in Dongcheng District of Beijing and is known as a "baker", said frankly: "To make bread soft, you have to use high-gluten flour, but most famous brands are imported and the price is much more expensive." Song Hongyuan, director of the Rural Economic Research Center of the Ministry of Agriculture, said: "Now people should not only eat well, but also eat safely and healthily, while our agricultural products have more staple goods, less high-quality and branded products, and the surplus of low-end agricultural products and the shortage of high-end agricultural products coexist."

The traditional motivation of increasing farmers’ income has weakened, and the new motivation can’t keep up. Zheng Fengtian, a professor at the School of Agriculture and Rural Development of Renmin University of China, said that the economic growth has slowed down and the wage income growth of migrant workers has been limited; With rising costs and falling prices, the growth rate of agricultural operating income has slowed down, and farmers are under great pressure to continue to increase their income.

The carrying capacity of resources and environment has reached the limit, and green production can’t keep up. The extensive management mode in many places has not changed fundamentally after the fertilization and shelling and flooding. China feeds 20% of the world’s population with 10% of the world’s arable land and 6% of the world’s fresh water resources. Behind the achievement is a huge price. The resources have been overdrawn for a long time, and the strings are getting tighter and tighter, and the ecological environment has lit up a "red light".

To solve these problems, we need to take unconventional revitalization measures in rural areas and find ways to make breakthroughs in system design and policy innovation.

The implementation of the rural revitalization strategy is to stabilize the "basic disk" of agriculture and rural areas-

Some people in the society have questioned whether it is necessary to strengthen the countryside when a large number of rural laborers enter the city. The proportion of agricultural output value is declining. Do we need to help agriculture? The inventory of some agricultural products is high, do you want to catch food?

"Agriculture, rural areas and farmers" are improving and taking the overall initiative. At no time can we ignore agriculture, forget farmers and be indifferent to the countryside. "Agricultural modernization is the basic support of the national modern economic system." Li Guoxiang, a researcher at the Institute of Rural Development of the China Academy of Social Sciences, thinks that which can be separated from agriculture, rural areas and farmers is stable growth, ensuring supply and expanding domestic demand? With the development of industrialization and urbanization, the share of agriculture in GDP will further decline, but the basic position of agriculture will not change, and the national conditions of a large number of farmers living in rural areas will not change. Even if the urbanization rate reaches 70% in the future, there will be nearly 400 million people in rural areas. Only when the "basic game" of agriculture and rural areas is stabilized can the whole game of national modernization be alive.

Bread is the staff of life. The problem of feeding 1.3 billion people has always been a top priority. "The better the food production situation is, the less we can relax." Yuan Longping, an 87-year-old academician of China Academy of Engineering, lamented, "Chinese’s rice bowl should be firmly in his own hands, and our rice bowl should mainly contain China grain."

Implementing the rural revitalization strategy is a necessary question to realize the goal of "two hundred years"-

Without agricultural modernization, rural prosperity and prosperity, and farmers living and working in peace and contentment, national modernization is incomplete, incomplete and unstable. This is by no means alarmist. In the 1970s and 1980s, some emerging countries took off at a high speed, but failed to handle the contradictions and problems in the transition period and fell into the "middle income trap". This warns us that to realize the modernization of the whole country, we must speed up the modernization of agriculture and rural areas.

To build a well-off society in an all-round way, the countryside is a short board. Ye Xingqing said that vigorously revitalizing the countryside can avoid agricultural decline and rural decline. Give priority to policy support, investment guarantee and public service satisfaction, so that all farmers can step into a well-off society in an all-round way, so that building a well-off society in an all-round way can be recognized by the people and stand the test of history.

Rural revitalization conforms to the new expectations of hundreds of millions of farmers, and the vast fields are full of new hopes.

Liu Yonghao, chairman of New Hope Group, who has dealt with agriculture, countryside and farmers for 35 years, said: "Implementing rural revitalization is another strategic opportunity for agricultural and rural development, which will activate the endogenous power of the vast rural areas and give birth to more good days!"

Chuanxi Wang, director of Daicun Village Committee in Lanling County, Shandong Province, said that in the past, the village had a weak foundation and the villagers’ life was tight. Nowadays, we have embarked on the road of characteristic and efficient agriculture, and everyone has a good life. "Rural revitalization, good policies continue, farmers can make great achievements, and the countryside will also make great progress. The whole village is twisted into a rope, which will definitely revitalize the countryside! "

The new path: five aspects of systematic efforts to accelerate the modernization of agriculture and rural areas

How to revitalize the countryside?

The report of the 19th National Congress outlines a clear path: according to the general requirements of industrial prosperity, ecological livability, rural civilization, effective governance and affluent life, establish and improve the institutional mechanism and policy system of urban-rural integration development, and accelerate the modernization of agriculture and rural areas.

The general requirements cover five aspects: rural economy, ecology, civilization, governance and life. Systematic efforts are made to make agriculture a promising industry, farmers an attractive profession and rural areas a home to live and work in peace and contentment.

Industrial prosperity is fundamental.

With a large population and a small land, resources are in short supply, so it is necessary to choose the right focus to realize agricultural and rural modernization. Song Hongyuan believes that based on the national conditions and agricultural conditions, it is necessary to speed up the construction of modern agricultural industrial system, production system and management system, and further promote the structural reform of agricultural supply side.

This is a broad adjustment of productive forces and a profound change of production relations.

-Optimize the structure and break through the price ceiling.

Adjust more, and adjust less. Shanxi Jinzhong HSBC Cooperative "runs in small steps, while watching and adjusting". After reducing grain corn last year, this year, it expanded the area of waxy corn and organic black adzuki beans. Chairman Zhi Peilin said: "The cooperative has a total of 32,000 mu of land, and the corn has taken the road of high quality and special use. Small miscellaneous grains have applied for trademarks, and members have increased their income by hundreds of yuan per mu after autumn."

"Market pricing, price compensation separation", the unbalanced ship turned around. The area of corn in the key areas of national corn structural adjustment has decreased, and the varieties in short supply have increased. The soybean in short supply in the market has increased by 8.7 million mu, and the miscellaneous grains have increased by 6 million mu. Addition and subtraction in the field, in exchange for a good hand in industrial layout.

-adjust the way and untie the "tight spell" of resources.

What should be retired should be retired and what should be reduced should be reduced. This winter, Liu Fusheng, a farmer in Xishengfo Village, Yanshan County, Hebei Province, relaxed a lot. As a seasonal fallow pilot village, the villagers changed from harvesting wheat and planting corn to planting only one season of corn, and received 500 yuan fallow subsidies per mu. The antagonistic farming that lasted for many years turned into adaptive farming, which gave the tired land a break.

Agricultural production is becoming greener. With the implementation of the five major actions of agricultural green development, the intensity of resource utilization has decreased, the effective utilization coefficient of irrigation water has increased to above 0.55, the application of pesticides in the country has achieved zero growth, and the comprehensive utilization rate of straw resources and the recovery rate of agricultural film have reached above 60%.

-adjust the system and solve the problem of "who will plant the land".

Driven by the cooperative, the land in Wuniu Village, Gulu Town, Yubei District, Chongqing changed its planting method, adjusted its structure and planted Xiantao plum, which grew to 2,500 mu in four years. Que Xingguo, the village party secretary, said: "This new variety plum is as big as a fist and looks like a peach. It has a good benefit. This year, it produced 100,000 kilograms, with an average of 1 kilogram sold in 20 yuan."

The new subject brings new vitality. Farmers’ cooperatives, family farms and other new business entities and service entities have developed rapidly, and more and more farmers have shared the dividends of modern agriculture.

Ecological livability is the foundation.

"In the past, we always envied the people in the city to live clean, but now the people in the city envy the people in our village to live a comfortable life." Zhong Jiaxu of Qinggangshu Village, Sandaoyan Town, Pidu District, Chengdu, Sichuan Province is very proud. In the past, garbage surrounded the village, sewage flowed, and a rural environmental improvement made the village greatly different. Promoting green development, coordinating the protection of landscapes, forests, fields, lakes and grasses, from the full implementation of the river length system to the improvement of rural human settlements, a series of new measures have been continuously strengthened, and more and more villages "can see the mountains, see the water and remember to live in homesickness".

Ye Xingqing believes that the modernization of agriculture and rural areas is also the modernization of harmonious coexistence between man and nature. It is necessary to strengthen rural ecological protection, turn the beautiful blueprint of agricultural green development into reality, and strive to build farmers’ happy homes, so that the countryside in the new era is not only green, but also beautiful.

Rural civilization is the key.

The "face" of the countryside is new, and the "lining" is also new. In Ningling County, Henan Province, in the past, weddings and funerals were carried out in rural areas, and some villagers became poor because of marriage. The local rural areas set up red and white councils, formulated new regulations, and changed customs. Civilized new styles are gradually gaining popularity, and the expenses for handling weddings, funerals and happy events in the county are generally reduced by 1/3.

Zhu Qizhen, director of the Institute of Farmers’ Issues of China Agricultural University, said that farmers should be rich in pockets as well as brains, not only in food and clothing, but also in spirit. Rural civilization construction should be integrated into all aspects of rural revitalization to continuously meet the needs of farmers for a better life.

Effective governance is the guarantee.

To solve the problem of rural governance, we must have new mechanisms and new rules. Yangping Village, Yunyang County, Chongqing implements grid management, with 10 independent grids and a studio to collect social conditions and public opinions, supervise environmental sanitation and mediate contradictions and disputes. Once chaotic villages have become advanced villages.

Tan Qiucheng, director of the Rural Governance Research Office of China Academy of Social Sciences, believes that with the accelerated transformation of rural social structure, farmers’ interests are diversified. Further improving the villagers’ self-government system, improving the level of grass-roots governance, and forming a standardized, orderly and dynamic rural governance mechanism can escort the rural revitalization.

Living well is the goal.

Multi-channel to increase income and accelerate the transformation of power. Jumping out of single agriculture, batches of agricultural products bid farewell to "washing, cutting and blowing" and become "green and rich" in supermarkets. New industries and new formats such as leisure agriculture, rural tourism and rural e-commerce are booming, and more farmers realize "making money at home".

Rural revitalization cannot leave ordinary farmers behind. The report of the 19th National Congress of the Communist Party of China proposed to realize the organic connection between small farmers and the development of modern agriculture. "The innovative management system is not a new stove, and the dominant position of family business cannot be changed." Chen Xiwen, dean of China Rural Research Institute of Tsinghua University, said that scale management is an inevitable trend, but the scale of agriculture not only refers to the scale of land, but also refers to the scale of service. Through the whole process of socialized service, one household can also move towards modernization.

New measures: urban and rural integration development, more resource allocation to "agriculture, rural areas and farmers"

The countryside and the city are born together and develop with each other, and they are a closely linked community of destiny. The development of China is inseparable from the prosperity of the city and the revitalization of the countryside.

Zhu Qizhen said that from "coordinating urban and rural development" to "integrating urban and rural development" and then to "integrating urban and rural development", the CPC Central Committee has a profound understanding of the changing trend and development law of urban and rural areas.

The integrated development of urban and rural areas is to make up for shortcomings and strong and weak items, and tilt more resource allocation to "agriculture, rural areas and farmers".

New policies and measures have been intensively introduced: let farmers live in peace of mind as soon as possible, and the central government will release 18.5 billion yuan of subsidies for rural dilapidated houses in 2018 in advance; Promote the integration of the three industries, and the relevant ministries and commissions issue opinions to promote the development of the agricultural industrialization consortium; In view of the problem of multi-head management and overlapping of agricultural funds, many departments have explored the establishment of a long-term mechanism for overall planning and integration …

-fill in the outstanding shortcomings.

"Well-off society is not well-off, the key is to look at fellow villagers." It is our party’s solemn commitment to let poor people and poor areas join the whole country in entering a well-off society in an all-round way. At present, poverty alleviation and development has entered the sprint period of gnawing hard bones and attacking villages.

Thousands of years of mountains and valleys, Dingxi, Gansu Province was once notoriously barren, and generations of farmers expected that "a knot in one’s heart would turn into Jin Doudou", but now their dreams have come true. Dingxi has been grinding a sword for ten years and carefully cultivated potatoes as an industry to enrich the people, which has driven 170,000 people out of poverty and become rich.

To tackle deep poverty, we are United in overcoming difficulties. A ruler can help the poor, concentrate firepower and pay more attention to quality. The central and relevant state departments and relevant provinces, in accordance with the general plan of precise poverty alleviation and precise poverty alleviation, focus on solving outstanding constraints, make up shortcomings as a breakthrough, strengthen the support and guarantee system, increase policy inclination, and concentrate on tackling key problems.

Zeng Yesong, a professor at the Central Party School, said that to get rid of poverty, we must make the poor people warm up and move, and abandon the mentality of "basking on the wall and waiting for others to send them a well-off life"; At the same time, the local authorities should not be eager for success, and they should be overweight at different levels.

-focus on rural people’s livelihood problems.

"In the past, the toilet was called a’ toilet’, with two bricks in a pit and a three-foot earth wall around it. Now, the public toilets are clean and practical, and the whole village looks superior. " Wang Yuanshan, a villager from Grandma Temple Village, tongshan district, Xuzhou City, Jiangsu Province, said. "Building a toilet seems like a trivial matter, but it is related to the happiness of farmers." Wang Weifeng, secretary of the Tongshan District Party Committee, said that the construction of 1,000 high-standard flush toilets in the whole region has solved the problem of people’s "difficulty in going to the toilet".

What the people expect, what the government does. The report of the 19th National Congress of the Communist Party of China put forward "attaching great importance to rural compulsory education" and "improving and unifying the basic medical insurance system and serious illness insurance system for urban and rural residents", aiming at the most urgent problems that the peasants are most concerned about, constantly improving the basic public services, and weaving the rural people’s livelihood security network more densely and firmly.

-lay a solid foundation for rural development.

In the early summer of each year, rape flowers in Kayang Village, Huangzhong County, Qinghai Province are in full bloom. In the past, the road into the village was bumpy, which affected the passenger flow; Nowadays, roads have been rebuilt in the county, with more tourists and villagers’ income increasing. In Huangzhong County, the rural roads in all poor villages will be rebuilt next year to make the rural "capillaries" smoother.

If you want to be rich, build roads first. To build rural roads, we must manage, protect and operate them well. The construction of "four good rural roads" has achieved tangible results, bringing popularity and wealth to rural areas, especially poor areas. From the gradual completion of water circuits and gas rooms to the continuous introduction of TV broadband, the financial investment is willing to give up real money, and the rural infrastructure is improving faster and faster.

Zheng Xinli, vice chairman of China International Economic Exchange Center, believes that to implement the rural revitalization strategy, we should find ways to open the gap, guide more urban production factors to flow to rural areas, accelerate the narrowing of the gap between urban and rural development, and provide a solid foundation for realizing agricultural and rural modernization.

New kinetic energy: reform breaks through key links and fully releases new vitality for development.

The reform started in the countryside and is deepening in the fields. In the past five years, various rural reforms have been further promoted, and the framework of "four beams and eight pillars" has been basically established. To implement the rural revitalization strategy, we must continue to deepen reforms, activate more elements such as "land, money and people", and fully release the vitality of agricultural and rural development.

How to change the land system? Stabilize the right to contract. The report of the 19th National Congress of the Communist Party of China made it clear that the land in contract relationship should be kept stable and unchanged for a long time, and the second round of land contracting should be extended for another 30 years after its expiration. This policy red envelope allows farmers to eat "reassuring pills."

After receiving the "Big Red Book", Ding Yan of Baishan Village, Queshan County, Henan Province is more practical: "The land area, schematic diagram and contract are all in the book. I transfer the land to the industrial park, and I can rent 1000 yuan per mu for one year. I can also work in the park. I can earn more than 1,200 yuan a month, and an acre of land can turn into two acres of benefits."

Release the right to operate. Rural land "separation of powers" awakens sleeping resources. In Liupanshui, Guizhou, a "three changes" reform has greatly changed the lives of many farmers. Li Ruming, a farmer in Ega Village, Miluo Town, Shuicheng County, didn’t expect that his 4 mu of land had three incomes: rent for circulation, salary for working, and dividends for shares. "Liberated from the land, now I am doing my own business, and I am more energetic." Li Ruming is full of longing for the future.

"No matter how it is changed, the collective ownership of rural land cannot be changed, the cultivated land cannot be reduced, the grain output cannot be changed, and the interests of farmers cannot be harmed." Zhang Hongyu, director of the Department of Economics and Management of the Ministry of Agriculture, said that by the end of November, the area of rural land was over 1.1 billion mu, and the next step will be to explore the transformation and application of the results of land ownership in promoting land circulation, mortgage financing and agricultural subsidies.

Where does the money come from?

"On the one hand, stabilize the agricultural input mechanism, on the other hand, increase rural financial innovation." Li Guoxiang believes that it is necessary to give full play to the leverage of financial funds and incite financial and social capital to invest more in agriculture and rural areas.

Deepen the reform of rural collective property rights system and turn resources into assets. Zhejiang rural areas explore "the three powers go to people, and the power goes with people", and the rural land is expensive by quantifying the shares of operating assets; Gongcun Village, Xiaotian, Lucheng City, Shanxi Province, carried out the reform of collective assets’ share rights, quantitatively converted collective assets into shares, and established economic cooperatives. The villagers got dividends and worked hard.

Who will revitalize the countryside?

The key to rural revitalization lies in people. Zheng Fengtian said that through institutional innovation, we should cultivate a "three rural" work team that understands agriculture, loves the countryside and loves farmers, mobilize the enthusiasm, initiative and creativity of hundreds of millions of farmers, stimulate the endogenous power of rural development, and inject more "living water" into rural revitalization.

After graduating from Qian Xin University in Tongling City, Anhui Province, he returned to his hometown to start a family farm. "High-quality agricultural products are highly sought after by urban consumers. I have transferred more than 1,000 mu of land, developed high-quality rice and planted pollution-free fruits and vegetables. As long as you work hard, you can make a difference in the countryside. " Qian Wei said.

With policies such as encouraging migrant workers to return to their hometowns to start businesses, "returning to the city" is becoming a craze, with more than 7 million entrepreneurs returning to their hometowns nationwide. At the same time, various forms of moderate scale operation have developed steadily, with more than 14 million new professional farmers and 1.88 million farmers’ professional cooperatives, accounting for more than 30% of the scale operation area.

The new era, new journey, and the grand blueprint for rural revitalization are enviable and inspiring. Under the leadership of the CPC Central Committee with the Supreme Leader as the core, with one heart and one mind, and a blueprint to the end, China’s "agriculture, rural areas and farmers" cause will surely open up a new world, and hundreds of millions of farmers will also embrace a happier and better tomorrow.

Director Feng Delun, do you have any misunderstanding about stealing movies? !

Special feature of 1905 film network In the current film market, there are countless movies about theft, and the early movies in Hollywood and Hong Kong are quite outstanding. In particular, Hong Kong-made pirated films have also inspired and influenced some rising stars in the Mainland to a certain extent.

Nowadays, the series, series, series, series, etc. we see all incorporate many new elements in theft. Of course, domestic peers are also unique in this field.

On August 11th, a film about theft directed by Feng Delun was officially released. Compared with most of the theft movies mentioned above, Grand Theft Auto only stays at the level of completing a film. While insisting on his own personality, Feng Delun lost his control as a director, and his action scenes were abnormal, and his emotional scenes were unattractive, wrapping a mediocre idea with mediocre camera language.

First, deconstruct the story: the new tricks can’t be played, and the old routines fail.

The main characters in the story of Grand Theft Auto are two men and one woman. Andy Lau plays the wily team boss Zhang Dan, Yang Shining plays the hacker genius Chen Xiaobao, and Shu Qi plays the beautiful thief Ye Hong. This is basically a necessary setting for stealing films. One is responsible for decision-making, the other is responsible for seduction, and the other is responsible for technical support.

In fact, it is not difficult to see that the two men and one woman in Grand Theft Auto are very much like the film "Crossing the Seas" directed by John Woo in 1991. In "Around the World", three people with distinct personalities were entrusted with the task of stealing famous products but were framed. The story of "Grand Theft Auto" is exactly the same.

In terms of scene setting, the two are similar. The famous painting "Herring’s Maid" in "Around the World" and the jewelry "Soul Spring" in "Grand Theft Auto" are all hidden in the old castle. How to steal them has become the key point of the film.Feng Delun’s handling method is similar to stealing famous paintings in John Woo’s movies, but it does not have the tense atmosphere and romantic temperament created by John Woo.

In "Around the World", Chow Yun Fat and Leslie Cheung staged a classic passage of hiding from infrared rays with red wine in the process of stealing famous paintings. The two of them responded to the organs in a vigorous and agile way, and they also took a picture of the friendship of "a thousand cups of friends are few".

"Grand Theft Auto" also has passages about infrared organs, but the handling method of the film is that Yang Shining directly uses hacking technology to turn off infrared rays, which reduces the stimulation of passing through infrared rays. Comparatively speaking, the handling of this paragraph is very thin.

In "Around the World", Wu Yusen contributed to the classic bridge of making a big auction and stealing keys in the ballroom. Chow Yun Fat and Cherie Chung danced a classic wheelchair dance, which blended romanticism into the crime theme.

Look at "Grand Theft Auto" again, and there are also dancing scenes in the process of stealing famous paintings. Ye Hong, played by Shu Qi, dances with the collector, played by Sha Yi, in order to steal Sha Yi’s fingerprints. However, the props tied to Shu Qi’s body didn’t arouse Sha Yi’s suspicion at all, and he passed this test very easily, which was somewhat rash in handling.

In addition to Across the World, Feng Delun’s Grand Theft Auto has other movies. Pierre, a policeman played by Jean Reno, is an important figure in the film and an old friend of Andy Lau in the film. His life seems to be aimed at catching Zhang Dan to gain a sense of accomplishment.

The chase between Jean Reno and Andy Lau is like another work directed by John Woo and Spielberg’s. Li Xiuxian, a policeman in Bloody Men, saw the other side of Chow Yun Fat as a killer. The same is true of the relationship between Jean Reno and Andy Lau in Grand Theft Auto. Jean Reno mentioned why he always wanted to catch Andy Lau, just because "he is the worst thief, he has patience and integrity", and the two gradually got to appreciate each other, and then they cooperated.

It is understandable to join the confrontation between Jean Reno and Andy Lau, which may make the film more interesting. However, Feng Delun made a mistake in controlling the overall rhythm, which made the final presentation more confusing. Moreover, it is an old routine for two people to reach an agreement to fight together, which can be expected from Jean Reno’s constant mention of the reasons for arresting him.

Covid-19 is strong in the north and weak in the south? The later, the lighter the "yang" symptom? Zhong Nanshan’s latest interpretation is coming.

  Zhong Nanshan. The pictures in this article are all live screenshots of the "National University Anti-epidemic Lecture Hall"

  Is it true that Covid-19 is "strong in the north and weak in the south" recently rumored on the Internet? Is Omicron infected once equivalent to a vaccination? Whether it is early or late, it is better to be together; Or the later you "turn yang", the lighter your symptoms will be? Under what circumstances should I go to the hospital? How do individuals protect themselves?

  On the afternoon of December 15th, Zhong Nanshan, an academician of China Academy of Engineering, gave a theme sharing on "the dynamics of the epidemic situation in COVID-19 and its countermeasures" at the "National Lecture Hall on Anti-epidemic in Colleges and Universities" hosted by Sun Yat-sen University, Peking University and Tsinghua University, and answered the above questions.

  Zhong Nanshan believes that there is no essential difference between the two strains. At the same time, he mentioned that one infection with Omicron is equivalent to one vaccination, but he did not agree with the statement that "it is better to be positive early and late, so it is better to be positive together". He said that the later "yang changes", the lighter the symptoms after infection may be. He believes that more and more infected people will be asymptomatic in the end.

  Covid-19 is "strong in the north and weak in the south"?

  Recently, some netizens think that after being infected with Omicron mutant, the symptoms of the northern infected people are more serious than those of the southern infected people.

  Zhong Nanshan also noticed the online related statements. In this regard, he said that at present, Omicron mutant BF.7 is popular in Beijing and Baoding, and Omicron mutant BA.5.2 is popular in Guangzhou and Chongqing. BF.7, the abbreviation of BA.5.21.7, is a mutant strain based on BA.5.2. Generally speaking, there is no obvious difference between the two strains.

  Zhong Nanshan said, "In fact, there are also some infected people with high fever and obvious body pain in Guangzhou. In Beijing, it seems that the fever is relatively high and the whole body aches, which may be related to the temperature or the further escape of the strain. "

  In addition, Zhong Nanshan mentioned that there is no more evidence, including the statement that "the virulence of the strains in Chaoyang District of Beijing is strong, and the virulence of the strains in Haidian District of Beijing is weak".

  Zhong Nanshan believes that there is no essential difference between the two strains.

  Zhong Nanshan also mentioned that at present, most people have no obvious performance after being infected with Omicron, that is, asymptomatic infected people; Some people have dry throat, sore throat, dry cough, headache, fever and other symptoms, that is, mild patients. Asymptomatic infections and mild patients reached 98%.

  One infection is equivalent to one vaccination?

  Regarding the "sequela" of COVID-19, Zhong Nanshan said that there are more than 200 symptoms of "sequela" of COVID-19, the main clinical manifestations of which are cough, dyspnea, olfactory dysfunction, fever, joint and muscle pain, headache, chest pain, brain fog (difficulty in concentration), sleep disorder, fatigue, fatigue and mood change.

  Zhong Nanshan mentioned that a Scottish study showed that asymptomatic infected people basically have no sequelae. At the same time, patients who have been vaccinated before infection have a lower risk of "sequelae" after infection, such as a 42% decrease in the risk of olfactory disorder, a 39% decrease in the risk of taste disorder, and a 40% decrease in the risk of hearing disorder.

  Zhong Nanshan also said that at present, many data show that after being infected with Omicron once, the rate of reinfection within one year is very small. After being infected with Omicron once (including asymptomatic), it is actually like being vaccinated once, and antibodies will be produced in the body.

  In this case, shouldn’t it be as some people on the Internet say, "It’s better to be sunny early and sunny late than to be sunny together"? Zhong Nanshan believes that this concept is not desirable.

  Zhong Nanshan said that although Omicron (BA.4/5, BF.7) infection is not terrible, most people can fully recover in 7-10 days; However, it is still very important to prevent infection, because China has a large population base, so we should be careful to prevent large-scale infection from affecting the normal social order or leading to the emergence of new mutant strains in the short term.

  In addition, Zhong Nanshan mentioned that people should not take the initiative to get sick, but because Omicron is highly contagious, there is a high probability of infection. However, the later the infection is delayed, the symptoms after infection may become lighter and lighter. "I believe that in the end, more and more infected people will be asymptomatic." Zhong Nanshan said.

  How do individuals protect themselves?

  At present, the spread of Omicron is very strong. How can individuals protect themselves?

  In this regard, Zhong Nanshan put forward eight suggestions to strengthen personal protection: strengthening protection (wearing masks, keeping a distance, reducing public gathering, etc.); Don’t be afraid of infection; Most infected people don’t need to go to the hospital; Pay attention to antigen testing at home; If you continue to have fever, you must go to the hospital; Older people suffering from general chronic diseases should also be vaccinated; It is not necessary to hoard medicine; "Old drugs are used for new purposes" must undergo rigorous experiments.

  In view of how young people cope with COVID-19, Zhong Nanshan also mentioned that the serious illness rate of young people infected with COVID-19 is very low. If there are no early warning symptoms in self-health monitoring after infection, they can continue to be isolated at home and release more resources for fever clinics and emergency treatment to elderly patients who need it more.

  "But if there are suspicious warning symptoms after self-health monitoring, you still need to see a doctor nearby in time." Zhong Nanshan said, "During the peak period of the epidemic, people who live with the elderly should also be vaccinated and strengthened, consciously reduce unnecessary going out and gathering, and do a good job of self-protection when going out to avoid infection. If there are suspected infection symptoms, the antigen self-test should be carried out in time. If it is positive, it should be isolated from itself (single room) to reduce contact with the elderly at home. "

  Zhong Nanshan has repeatedly stressed that it is necessary to accelerate the intensified vaccination of vaccines (especially heterogeneous vaccines). He pointed out that the effect of preventing infection will not be enhanced if the same vaccine continues to be vaccinated, but the effect of preventing severe diseases still exists; The effect of immunization with heterologous vaccine (subunit protein vaccine/adenovirus vaccine /mRNA vaccine on the basis of two doses of inactivated vaccine) is obviously improved. Therefore, it is necessary to strengthen the immunization of the elderly and vulnerable groups. At the same time, it is necessary to strengthen the vaccine protection of medical personnel, and accelerate the research and development and approval of nasal spray and inhalation vaccines.

China-Central Asia Summit | Show you five different Central Asian countries!

  Central Asia starts from the Caspian Sea in the west, borders China in the east, Russia in the north and Iran and Afghanistan in the south, including Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan. In 1992, China established diplomatic relations with five Central Asian countries.

  Central Asian countries are located in the center of the Eurasian continent, which is the only place where the ancient Silk Road passes, crossing China and the West, connecting the North and the South, where Chinese and foreign goods circulate, and where eastern and western civilizations meet. Nowadays, in the ancient and vast land of Central Asia, the Silk Road is shining again.

  Kazakhstan: Hometown of Wild Tulips

  As the largest landlocked country in the world, Kazakhstan spans two continents, Asia and Europe, with a vast territory and a sparse population. Kazakhstan has a land area of 2,724,900 square kilometers, ranking ninth in the world. By the beginning of March 2023, the population of Kazakhstan exceeded 19.8 million. The capital of Kazakhstan is Astana, the national language is Kazakh, and Russian and Kazakh are both official languages. Kazakhstan is the pioneer and important hub of the Silk Road Economic Belt.

  Kazakhstan is regarded as the hometown of wild tulips, and most tulip varieties in the world originate from Kazakhstan, which is an important reason why Kazakhstan has designated it as the national flower. Kazakhs attach great importance to the protection of wild tulips. There are more than 30 kinds of wild tulips in Kazakhstan, 18 of which are recognized as endangered species and listed in the "Red Book" of protection list. If the wild tulips listed in the list are illegally harvested, the most serious penalty is 3 years’ imprisonment. Being associated with tulips adds romance to this country.

  The residents of Kazakhstan are composed of about 130 ethnic groups, including Kazakhs, Russians, Ukrainians, Uzbeks, Germans and Tatars, among which Kazakhs account for 70.6% and Russians account for 15.1%. The residents mainly believe in Islam and Orthodox Church.

  On March 22nd, 2023, various cultural and sports activities were held in Astana to celebrate the Na Urus Festival. NaUrus Festival (also known as Nowruz Festival) is one of the most important traditional festivals in Central Asian countries, marking the arrival of spring and the beginning of a new year. Xinhua News Agency (photo by Ospanov)

  Due to the specific natural conditions and social environment, the people of Kazakhstan have unique customs and customs. Kazakhs are good at singing and dancing, and all kinds of cultural and sports activities, such as playing, dancing, kicking shuttlecock, etc., are popular every holiday, and various competitions such as falcon, horse racing, wrestling, chasing girls, grabbing sheep, wrestling at once and archery are also held. Kazakhs worship wolf totem, and myths about wolves are widely circulated among the people.

  The traditional foods of Kazakhs are pasta, horse meat, horse milk and camel milk. The most common drink is milk tea. The national dish is "Bieshi Bahrmark", which means "Five Fingers". The main ingredients are boiled horse meat with salted noodles smeared with oil, which is a local special food on holidays. In the severe winter, many people living in the cold areas in the north eat horse meat to resist the cold.

  Almaty is the largest city in Kazakhstan. There is a street named after China musician Xian Xinghai, and there is a street named after Kazakhstan musician Baikadamov not far away. Two parallel streets record the friendship between two musicians during the war. Through time, the touching stories of the two musicians have been passed down from generation to generation.

  2024 is the year of Kazakh tourism in China. Kazakhstan is rich in tourism resources, and the most famous scenic spot in the southern region is Chalun Canyon. The best tourist destination in the western region is Karadji Ye Depression, which is the second lowest place in the world, and the Caspian Sea is located here. In Kazakhstan at the northern foot of Tianshan Mountain, about 50 kilometers away from Almaty, it is an important site on the Silk Road — — Lachart site attracts the attention of archaeologists from China and Kazakhstan.

  There are many historical sites in Kazakhstan, including the mausoleum of Hoza Ahmet Yasavi, which is one of the most famous historical sites in Kazakhstan and a representative of medieval architectural art in Central Asia. Tangbala rock painting, which is the first historic site in Central Asia to be included in the UNESCO World Heritage List; The remains of Tass Palace in akol, full of mystery and historical secrets; Zarkent Mosque with Chinese style, a large wooden building complex, does not use a nail.

  Kyrgyzstan: "Little Switzerland"

  The beautiful natural environment, mountains and lakes make Kyrgyzstan win the reputation of "Little Switzerland in Central Asia", attracting millions of tourists from all over the world every year.

  Kyrgyzstan has a land area of 199,900 square kilometers, mountainous territory with an average elevation of 2,750 meters, and 90% of its territory is above 1,500 meters above sea level, with a continental climate. By April 2023, the population of Kyrgyzstan was about 7 million. There are more than 80 ethnic groups in China, and more than 80% of the residents believe in Islam. Kyrgyz is the national language and Russian is the official language. Bishkek, the capital, located in the Chu River Valley, is a famous city in Central Asia, and now it is the largest city in China with a population of over one million.

  Tourists who come to Kyrgyzstan often want to visit the "guardian of heaven in Kyrgyzstan" — — Issyk, L. It is a famous summer resort in Central Asia, with a length of 182 kilometers, a width of 61 kilometers, an area of more than 6,000 square kilometers, and the deepest part of the lake reaches 702 meters, making it the second largest alpine lake in the world.

  Lake Issyk-Kul means "warm lake" in Kyrgyz. It is not frozen all year round and the lake is clear and transparent. Fantasy and mystery are the words most used by people who have been to Lake Issyk-Kul to describe it. Standing by the lake, the blue and wide lake is like the sea. The snow-capped mountains on the south bank are like a mirage in the clouds. Sunlight shines from the cracks in the clouds on the lake, and the lake is blue and green, like a jewel that blends with each other.

  In 2011, the reporter visited Calabor Yi Village on the north bank of Lake Issyk. There is a little-known museum of ancient rock paintings in the village, and local researchers are convinced that one of the stones is also carved with a portrait of China and Zhang Qian when he went to the Western Regions in the Han Dynasty.

  Tajikistan: the "country of mountains" where eagles fly.

  Tajikistan is located in the southeast of Central Asia, bordering China in the east, Afghanistan in the south, Uzbekistan in the west and Kyrgyzstan in the north, with a land area of 143,100 square kilometers, making it the smallest country in Central Asia. Tajikistan is known as the "country with high mountains", and its territory is mountainous, with a mountainous area exceeding 90% of its land area.

  On April 12, 2019, several men took a group photo with their mobile phones in Yawan District, Hadron Prefecture, 70 kilometers away from Dushanbe, the capital of Tajikistan. Xinhua News Agency reporter Bai Xueyu photo

  Thanks to abundant mountain melting snow and huge terrain difference, Tajikistan is rich in hydraulic resources, ranking eighth in the world in terms of reserves and ranking first in the world in terms of per capita possession. The Fichenko Glacier, located in central Tajikistan, has a total length of more than 70 kilometers and a maximum thickness of about 1000 meters. It is the longest glacier in the world except the Antarctic and the Arctic. The tower is rich in precious metals such as lead, zinc, tungsten, gold, silver, tin and copper, as well as mineral resources such as oil, natural gas, halite, boron and coal.

  Turkmenistan covers an area of 491,200 square kilometers, about 80% of which is covered by Karakum Desert. With a population of more than 6 million, it consists of more than 120 ethnic groups, of which Turkmen account for 94.7%, and the vast majority of residents believe in Islam.

  Turkmenistan is extremely rich in natural gas resources and is known as the "country of blue gold". Because of the "gas", spontaneous leakage of underground natural gas in Turkmenistan, blowout in oil and gas operations and other "gas leakage" phenomena are common. Dawaza natural gas pit, located in the center of Karakum desert, is the most serious place of "gas leakage", and it is also the legendary "Hell Gate". Viewed from the air, this pothole is like a huge crater, with a diameter of about 70 meters and a depth of about 20 meters. Boiling mud and bright orange flames rise from the abyss, as if the devil would jump out of it at any time, so the locals named it "Hell’s Gate".

  Ashgabat, the capital, is known as the city of marble. In this city, a large number of building facades, including government offices, are inlaid with white marble. Against the background of white marble, the city surrounded by desert looks neat and bright. Ashgabat is also known as the "Fountain Capital", where water is more expensive than oil, but the fountain landscape can be seen everywhere.

  Turkmen people’s living customs have distinctive ethnic characteristics. Most people are used to eating spices such as pepper, onion, fennel and mint. Traditional foods include hand-picked rice, grilled naan, barbecue and braised naan in broth. Turkmenistan people like to eat grapes, melons and other local fruits, as well as dried apricots, raisins and walnuts. Tea is the main beverage in Turkmenistan, and camel milk is often used to cool off in summer.

  The region where Turkmenistan is located was once one of the important centers of Central Asian civilization. It is the only place where the painted pottery road, the glass road, the golden road road, the lapis lazuli road, the grassland road, the spice road and the bronze road pass. It is known as the "crossroads of seven roads on earth" on the Silk Road.

  Historically, China and Turkey have formed close commercial, economic and cultural ties. According to the historical narrative of Turkmen people, many centuries ago, they exchanged tea, silkworm eggs, silk and porcelain with Chinese through the Silk Road with Akhal Jiejinma (bloody BMW) and Arabica (Central Asian Shepherd Dog). It is worth mentioning that the Arable Dog and Akhal Jiejinma are national symbols of Turkmenistan, and the image of Akhal Jiejinma is drawn in the center of Turkmenistan’s national emblem.
