Looking back at the 1998 Beijing influenza, the perfect battle of independent Chinese medicine against the epidemic

Focus on Health China Traditional Chinese Medicine (First Health Report by Lu Jiawei)

In the preface:

Time is the grave where history is buried. No matter how many years have passed, great events and small feelings that have happened, when they are recalled, the fragments of time string it together and turn it into a series of intriguing stories. That year, when people were still immersed in the melody of the popular song "Come and meet in 98, meet in the warm affection under the silver moonlight", a sudden pandemic swept through Beijing. ……

Lu Jiawei

After the Spring Festival in 2022, Omicron was ravaged, and millions of people died in Hong Kong. Shanghai was shut down for more than a month due to the epidemic, and people’s production and life were greatly affected. In May, the epidemic in Beijing was also on the rise. It can be said that this is the biggest black swan incident at present. What good methods will Chinese medicine have in the face of the epidemic? We might as well review the history to find some useful information, especially the anti-epidemic deeds of Chinese medicine in Beijing in 1998.

After entering the winter in 1998, the cold, accompanied by the flu, quietly spread in Beijing.

One day in November, the number of outpatients in Beijing Dongzhimen Hospital suddenly increased, and the patients in the hospital were crowded and in a hurry. Due to the unclear positioning of the affiliated unit of the hospital at that time, a large number of backbones began to transfer to the Second Affiliated Hospital. This is the third large-scale technical delivery of Dongzhimen Hospital after the China-Japan Friendship Hospital and Wangjing Hospital, and the technical strength of the hospital has lost a lot. In this case, facing the surging patients, the hospital took it easy from top to bottom, from outpatient to emergency, and methodically used traditional Chinese medicine to suppress a wider range of popular trends.

Jiang Liangduo, Zhou Ping ‘an and other expert teams randomly observed 472 patients in outpatient and emergency departments, and filled in their medical history, symptoms, signs, laboratory tests and other items in the pre-designed observation table for influenza patients, including 253 males and 219 females, the oldest being 87 years old, the youngest being 14 years old, and the average being 52.3 years old.

Dongzhimen Hospital in 1990s

After collective consultation, TCM experts finally determined the characteristics of the flu: rapid onset and similar symptoms.

First, general malaise, runny nose or throat discomfort occurs, and then fever and anhidrosis occur quickly. Fever is mainly high fever, with cold and heat alternating, nausea and vomiting, anhidrosis, general pain, headache, cough, sore throat, yellow or white phlegm, dry stool and yellow urine. Most patients have a taste, dry cough and little phlegm.

Some patients developed tracheitis or pneumonia after fever. Among them, the virus-infected pneumonia with normal white blood cells and increased lymphocytes is about 33%, and patients with basic diseases are easy to cause complications, which makes the condition worse or worse.

With the sharp increase of outpatients, after clarifying the causes and symptoms, in the face of the menacing pandemic, an anti-epidemic war in the hospital began.

Experts from all walks of life actively face the prescription for the right medicine, and the prescription prescribed by Dr. Zhou Ping, director of the emergency department, is based on the classicsMaxing Shigan Decoction is the monarch, supplemented by heat-clearing and detoxicating drugs such as Scutellaria baicalensis Georgi and Forsythia suspensa.The clinical effect is excellent, and it only takes about 1 day to reduce the fever at the beginning of the flu. (This core prescription performed well, and was later registered as a hospital preparation Jiedu Qingfei Mixture. )

At the end of 1998, I happened to be in charge of the management of the hospital decocting room.

Dongzhimen Hospital began to use the decocting machine at the end of 1997, which is the first top-three hospital in Beijing to use the decocting machine. At the beginning of November, there was a demand for the prescription of cold medicine in the outpatient department. At first, it looked like a few hundred yuan a day. After a few days, the demand increased greatly, and overtime took up all the machines. The hospital urgently purchased six or seven packaging machines for this purpose, and also organized a large group of people to fill 200ml plastic bottles. It wasn’t long before the peak came one after another, and the whole pharmacy department started to meet the flood of outpatient demand, and all kinds of means went into battle.

The author provides the old photos of the first health report.

Out-patient Chinese pharmacy sells the agreed prescription directly, and the preparation room has 1 ton, 2 ton boiling extraction tanks and two open pots to extract several times throughout the day, and the decocting room is responsible for filling. At the peak, there are more than 30,000 bags or bottles of substitute decoctions every day, which can meet the dosage of 5,000 people for three days. A small house dedicated to storing substitute decoctions is emptied after working overtime all morning at night, and there are many people who buy and take medicines at the door of the decocting room every day. What impressed me most was that China Bank purchased 6,000 bags with a prescription.

One of my brothers also got the flu. Fortunately, the fried medicine was delivered in time, and the fever dropped the next day. Afterwards, he said, Jiawei, you saved my life. According to him, the high fever persisted and he felt like he was going to die. That was the first time I heard that the flu was still so harmful.

According to the timeYan Xu, Director of Pharmacy Department.Memories: "That year was a big flu in five provinces and cities such as Hebei and Inner Mongolia. Many people found Dongzhimen Hospital after intravenous drip. Line up at the window to buy medicine until the door of the hospital. But the order is particularly good, there is no noise and congestion, and thank you for getting the medicine. Outpatient decoction pieces can’t be supplied, and several companies help them to take medicine day and night. The leaders of the hospital also brought people from various departments to help. Zhongnanhai named Dongzhimen’s cold medicine, and finally I personally escorted it to Zhongnanhai. "

The whole epidemic lasted until the spring, and Dongzhimen’s cold medicine was not only loved by the masses, but also recognized by the highest authority. Later, there was a demand for outpatient services in winter, which lasted for several years.

At that time, there was no decocting machine in Beijing Hospital of Traditional Chinese Medicine, and the prescription was mainly based on agreement. As a result, the patient was sued to the Health Bureau: "It is said that Chinese medicine needs dialectical treatment, and we can see how to get the prepared medicine for colds." The Beijing Evening News also reported on this. It can be seen that the general public does not know that traditional Chinese medicine can be used to prevent and treat the epidemic in the early stage. Beijing Hospital of Traditional Chinese Medicine gave a reasonable explanation, and it was popularized in the mass media. This is the most basic version of Chinese patent medicine, and it is also the cradle of traditional Chinese medicine preparations and new drugs. The predecessor of Tasly Danshen Dripping Pills is the agreed prescription.

The city’s Chinese medicine medical institutions are also fully fired, and it is conservatively estimated that the daily consultation capacity will reach 700,000-100,000 people. For mild or initial symptoms, it usually takes 1-3 days to solve the problem. In short, a pandemic involving 1.2 million people diagnosed with symptoms was finally put out after two or three months of struggle, and the great gods in the field of Chinese medicine did not participate in the war, and only the Mesozoic masters played to win!

afterwards

According to the epidemiological retrospective survey released by Beijing Health and Epidemic Prevention Station in the spring of 1999, the incidence of influenza in Beijing was 10.1% from November 1, 1998 to January 31, 1999, when more than 1 million people in the city suffered from influenza.

What is the concept of this data today. It is equivalent to more than 2 million people in Beijing being diagnosed! 2.5 million people in Shanghai were diagnosed! Putting it in the country is 140 million people diagnosed! At that time, Beijing had a resident population of 12 million, which was equivalent to the level of medium-sized countries in Europe, so this flu data definitely had various analytical and statistical values.

In 1998, social development was relatively backward, and the per capita salary of Beijing employees was only about 1100 yuan per month. At that time, it was impossible for all staff to do nucleic acid and build a shelter. Mobile phones were still luxury goods, and it was impossible to have health codes and travel codes to control suspected people.

Life should go on, and the epidemic should be defeated. At this time, it is time for Chinese medicine to show its power, and Chinese medicine has indeed done it. In 1998, Chinese medicine won the battle against the Beijing flu epidemic. From the bits and pieces of the Dongzhimen Hospital affiliated to Beijing University of Chinese Medicine to find out the real situation of this forgotten pandemic, it may be enlightening for today’s anti-epidemic.

In 1998, Beijing University of Chinese Medicine gathered a great number of giants. Tung Chee-hwa, Cheng Shennong, Liu Duzhou, Wang Mianzhi, Liu Bichen, Yang Jiasan and Yan Zhenghua were the kings of Chinese medicine in that era. In Mesozoic, Wang Yongyan, Du Huaitang, Tian Delu, Guo Weiqin, Zhou Pingan, Wang Qi, Jiang Liangduo and Tian Jinzhou gathered together. Chen Lixin, Ye Yong ‘an, Wang Yaoxian, Liu Qingquan and Jong Li, the younger generation, have thrived, and the three generations of the old, middle-aged and young people have cast a celestial group in the field of Chinese medicine.

Memorabilia of influenza in Beijing after liberation

The shadow of influenza has always lingered in human society. According to historical records, there have been several major influenza outbreaks since the liberation of Beijing.

In 1957, influenza A/type 2 caused a widespread pandemic, and more than 50% people in Beijing were infected. Some factories and schools were shut down, which not only brought serious harm to people’s health, but also caused great losses to the national economy.

Type A 3 was popular in China in 1968, and soon spread all over the world.

In 1977, Type A 1 reappeared, which became popular among teenagers.

At the end of 1988, there was a moderate epidemic of influenza in Beijing, and the incidence rate was above 10%.

In 2003, the team of Deng Tietao, a master of Chinese medicine for SARS, created four zero records: zero infection, zero transfer to hospital, zero severe illness and zero death.

Achievements of Chinese medicine practitioners

Lu Bingkui, commander of Chinese medicine, wrote to Premier Wen asking Chinese medicine to go into battle to treat SARS.

Ren Jixue, a master of traditional Chinese medicine, took the SARS preventive prescription for 90,000 people in Jilin, and no one was infected. Sars is a curtain call for Chinese medicine practitioners, and it also leaves a strong legacy for the history of Chinese medicine’s anti-epidemic.

Lu Bingkui, commander of traditional Chinese medicine, wrote at the age of 89 that "medical health should make people live on the road of disease-free health, and people with normal physiological functions should not get sick." This is a popular explanation of the traditional Chinese medicine that "healthy qi should be kept inside, and evil should not be done" to treat the disease before it happens.

postscript

I should say,The 1998 Beijing pandemic should be the last battle for Chinese medicine to fight the epidemic independently and win completely.However, it is enough to prove that it is possible for Chinese medicine to lead the fight against plague, and it also proves that Chinese medicine has the advantages of advanced nature across time and space, rapid recovery of patients and super preventive ability, and finally realizes a win-win situation with extremely low social damage against epidemic.

In the fight against plague, Chinese medicine can face the epidemic directly without infection, and the treatment principle is like thunder, which can quickly wipe out the sequelae. For critically ill patients, it can gradually recover to save their lives, and the trinity of "prevention, treatment and rescue" constitutes a system.

Traditional Chinese medicine (TCM) has been developing and expanding since Zhang Zhongjing, a doctor, and has established a set of theoretical methods and classic prescriptions of "prevention, treatment and rescue". This is a super versatile arsenal, especially for respiratory infectious diseases. No matter where the enemy comes from, it can respond quickly at the first time and has the ability to destroy the enemy before it happens.

With the great development of society, people’s living standards have been greatly improved, and it is difficult for severe infectious diseases such as plague and cholera to make a big splash. Globalization makes world travel the norm, and domestic transportation is extremely convenient. The objective reality makes the spread of respiratory diseases extremely rapid and extensive, which may be the main contradiction of future epidemics.

It is urgent to explore the anti-epidemic energy of traditional Chinese medicine in advance, so as to make it a systematic and regular anti-epidemic main force, which will also be a national weapon to ensure the smooth and stable development of the country.

Author’s notes

Lv Jiawei, born in 1969 in a family of traditional Chinese medicine, is the youngest son of Lv Bingkui, founder and commander of traditional Chinese medicine in New China. At the age of 20, I followed around to participate in various Chinese medicine activities, and was responsible for sorting out medical records and life information. Gradually understand the ancestors’ pursuit and academic thoughts in the cause of traditional Chinese medicine under the influence of years.

Novel coronavirus Inactivated Vaccine Obtained Clinical Trial Approval! Related clinical trials have started!

The first in the world!

April 12

Novel coronavirus Inactivated Vaccine Obtained Clinical Trial Approval!

Related clinical trials have started!

There is no specific therapeutic drug in novel coronavirus, so the research and development of vaccine has attracted much attention and expectation. A few days ago, there was heavy news about vaccine research and development in Covid-19 — — Covid-19 Inactivated Vaccine Obtained Clinical Trial Approval! It is a big step forward for us to welcome the protection of vaccines.

On April 12th, a class of new drugs — —Inactivated novel coronavirus vaccine, obtained the clinical trial license of National Medical Products Administration. this isThe world’s first inactivated vaccine in Covid-19 with clinical trial approval.

It is understood that the vaccine is related.Clinical trials have started simultaneously.. According to the relevant national laws and regulations, it has been fully prepared for emergency use.

Previously, Sinopharm Group China Bio took the lead in developing a "searchlight" for diagnosing Covid-19 — —Nucleic acid molecular detection kit, the first to successfully launch the "ballast stone" for the treatment of critically ill patients — —Plasma technical standard and clinical treatment scheme of convalescent patients; Coupled with this research and development of Covid-19’s "killer" for the decisive battle against the epidemic — —Inactivated COVID-19 vaccineA series of major scientific research achievements have provided strong support for realizing the goal of "diagnosis, treatment and prevention" in COVID-19.

On February 1st, Sinopharm Group China Bio, as the lead unit, won the key project of "Public Safety Risk Prevention and Control and Emergency Technical Equipment" of the national key R&D plan of the Ministry of Science and Technology.2019-nCoV inactivated vaccineEmergency establishment of the project (project number is 2020YFC0842100).

Under the strong leadership of the CPC Central Committee and the State Council and the strong support of the Ministry of Science and Technology, the Ministry of Industry and Information Technology, the Health and Health Commission, National Medical Products Administration and the State-owned Assets Supervision and Administration Commission of the State Council, Sinopharm Group China Bio has successively overcome a series of key technologies in the production and quality control of COVID-19 vaccine, such as vaccine strain screening, virus seed bank establishment, antibody preparation and identification, detection method establishment, production technology research, compatibility and formula screening, determined the technological route and product quality attributes, and quickly carried out and completed the evaluation of animal’s in-vivo effectiveness and safety, with successive achievements. The successful approval of the clinical trial will further lay the foundation for the "high-speed" start of inactivated vaccine in Covid-19.

inactivated vaccine

Inactivated vaccine refers to a vaccine that makes the virus lose infectivity and replication by physical or chemical treatment, but retains the activity of the virus that can cause human immune response.

Inactivated vaccine is the most effective vaccine research and development path for emerging infectious diseases.

Compared with other types of vaccines (such as genetically engineered recombination vaccines, adenovirus vector vaccine, attenuated influenza virus vector vaccine and nucleic acid vaccine),The inactivated vaccine has advanced research and development technology, mature production technology, controllable quality standards and good protection effect.Sinopharm Group China Bio has large-scale inactivated vaccine production capacity,The declared COVID-19 vaccine clinical trial batch output exceeds 50,000 doses. After mass production, each batch output exceeds 3 million doses, with an annual production capacity of more than 100 million doses.

Vaccine is very important for epidemic prevention and control. Since the outbreak, the scientific research team of the State Council Joint Prevention and Control Mechanism has set up a special class for vaccine research and development, according toInactivated vaccine, recombinant protein vaccine, adenovirus vector vaccine, live attenuated influenza virus vector vaccine and nucleic acid vaccine are five technical routes.A total of 12 R&D tasks have been laid out, and they are all progressing steadily at present.

Previously, the adenovirus vector vaccine of the Institute of Military Medicine of the Academy of Military Sciences has been approved to carry out clinical trials, and now it has entered the second phase of clinical trials.

The inactivated vaccine approved for clinical trials this time is a kind ofVaccines that kill pathogenic microorganisms but still maintain their immunogenicityIt has the advantages of mature production technology, controllable quality standards, wide protection range, etc., and can be used for large-scale vaccination, and there are internationally accepted standards to judge the safety and effectiveness of vaccines.

Inactivated vaccines in China have a good research foundation, and inactivated hepatitis A vaccine, inactivated influenza vaccine, inactivated hand-foot-mouth disease vaccine and inactivated polio vaccine have been widely used.

In this epidemic prevention and control war, the six biological products research institutes in Beijing, Wuhan, Chengdu, Lanzhou, Shanghai and Changchun and the China Biotechnology Research Institute of Sinopharm Group China Biological actively played the role of scientific research, focusing onCovid-19-related diagnostic reagents, plasma for patients recovering from illness, anti-novel coronavirus immunoglobulin, inactivated novel coronavirus vaccine, recombinant genetic engineering vaccine, monoclonal antibody, horse anti-Covid-19 serum.Waiting for scientific research.

Among them, Sinopharm Group China Bio-Shanghai Jienuo developed.Covid-19 nucleic acid molecular detection kit, the first batch has passed National Medical Products Administration certification and EU CE certification, and has supplied more than 1.3 million people to provinces, cities, Hong Kong, Macao and abroad.Plasma treatment technology for recovered patients, recommended by the joint prevention and control mechanism of the State Council, was included in the "Diagnosis and Treatment Plan" of National Health Commission. As of April 7, 2169 people have been collected plasma in China, and 648 cases have been treated clinically, with remarkable results. This therapy has been adopted and used in many countries.

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.

After all, in today’s market, there are not many models that can have such an appearance design at the same time. This upgrade of Xingyue L has another better choice. Looking forward to its performance after it is officially launched. It should become a dark horse.

The first season of "Running Man" ended perfectly, and Zheng Kai wept emotionally


The first season of "Running Man" ended perfectly, and Zheng Kai wept emotionally


Since the broadcast on October 10, 2014, until the end of the last episode last Friday, Zhejiang Satellite TV’s reality show "Running Brothers" has accompanied the audience through 99 days full of laughter and positive energy. The seven "Running Brothers" have also won popular popularity with their true temperament and fighting spirit. With the successful conclusion of the first season of "Running Brothers", "Running Little Prince" Zheng Kai still brought full laughter with his cute and cute performance, but he couldn’t help but shed tears at the end.

Zheng Kai turned into a sea lion in seconds, and the toad skill shone brightly


This time, "Running Brothers" set the identities of superpowers for the seven "Running Brothers", and their "divine skills" were based on traditional Chinese martial arts stories. Zheng Kai obtained the identity of "Ouyang Feng", and he introduced himself as "Ouyang Kai" with a serious fist, and had a stunt called "Toad Gong".


In order to retrieve the lost martial arts, everyone first came to the swimming pool to be tested. Everyone put on waterproof clothes and stepped into the floating board in the water. Deng Chao said that standing in the water "I feel like a sea lion!" Zheng Kai, who had excellent imitation ability, immediately became interested, got down and propped up his upper body, made a "< unk > < unk >" cry and acted cute to slap the water "wagging his tail", which was cute and looked like a sea lion. He interacted happily with Deng Chao "Brother Lion", and finally slid into the water to amuse the audience.


Zheng Kai wept emotionally and did his best to "run" the first season


In the Science and Technology Museum where the famous brand war was held, Zheng Kai found a mini running speed test area, which was a familiar sprint track. Zheng Kai couldn’t stop itching to test his skills, showing professional starting movements and amazing explosive power, easily ran a good time of 2.4 seconds, and broke a personal record, worthy of the reputation of "Cheetah".


Zheng Kai possessed a powerful "Poison Fog Spray" skill, which was about to be gained. However, "Appendix Brothers" Chen He launched the "Great Shift of the Universe" skill, which moved the threatening Deng Chao and Zheng Kai to another floor, and stipulated that the starting action was for Deng Chao to ride on Zheng Kai and hold his brand name, in order to give Deng Chao the opportunity to eliminate Zheng Kai. However, facing the end of the first season of "Running Brothers", Deng Chao couldn’t bear to tear off the famous brand. After the cute Zheng Kai turned over, he understood the captain’s intentions and rewarded this last "run" with a more serious and energetic performance, leaving the audience with a always sunny handsome and hard-working "Running Little Prince".


Finally, Zheng Kai was eliminated in the encirclement and suppression of several people and left the battlefield. Zheng Kai couldn’t help but cry emotionally, and embarrassed to lift the corner of his clothes to block his crying red eyes. The true temperament of not leaving was touching. Zheng Kai said on Weibo: "Thank you for your company for 99 days, thank you 10 million Kaijia for your support! In 2015, Zheng Kai’will be angry ‘!" Warm farewell in a relaxed and joking tone, and netizens left messages saying "It hurts to see you cry!" "See you in the second season!"

　　 　　The awards ceremony on November 20 has entered the countdown stage, and the executive committee announced the last wave of award winners on the 17th. "Ip Man 2" and "Detectives Di Renjie" were both shortlisted for "Best Action Design" by "Big Brother" Hong Jinbao, and the long-lost Golden Horse Actor Leung Ka Hui were invited to present the awards. Lin Zhiling, who has attracted much attention, finally took a leave of absence from the crew and successfully attended the Golden Horse event. Taiwan’s potential actresses including Li Kangyi, An Yixuan, Xie Xinying, Chen Yanxi and others will serve as the introducers of the best film, marking a beautiful end to the awards ceremony.

　　 　Hong Jinbao, who has long missed the Golden Horse Awards ceremony because of his filmmaking, has been shortlisted for two films at the same time this year. Can he win with the tiger-like "Ip Man 2" or the dazzling and brilliant "Detective Dee Renjie"? The ceremony will be announced on the same day. Hong Jinbao started working as an action director very early, and is best at neat and powerful martial arts moves with a little humor, which makes him not only occupy a unique position in Chinese movies, but also attracts Hollywood to find him for filming. This year, he specially set aside a schedule for the annual Golden Horse Awards event. In addition to paying tribute to this year’s theme – "Action", he can be called the most "weighty" awards guest this year.

　　 　A few days ago, Chen Wenqian said on the program that "he only likes Liang Jiahui and doesn’t like Weizai", which created a lot of news topics. It can be seen that Liang Jiahui, who has been a high-quality and good man for many years, still has a place in the new generation of handsome guys. His excellent acting skills can be said to be a regular finalist for the Golden Horse Awards. Wang Xueqi, who filmed "October Siege" with him, once said that Liang Jiahui took great care of everyone on the set, and would cook chicken soup for everyone to drink from time to time, and took care of him even more.

　　 　Sister Zhiling has performed well in movies in recent years, and many big directors have designated to cooperate with her. The brave breakthrough starring her has made everyone see her determination and strength. After the 10/1 shortlist was announced, Sister Zhiling was the first on the list of inquiries. Not only did the audience look forward to her, but the media also frequently paid attention to her movements. The public relations and jewelry industry of various clothing brands led the way, just waiting for Lin Zhiling to nod and agree to attend the award ceremony. Presumably, the starry sky will shine on the day of the ceremony, and it will be very beautiful.

　　 　The best film introducer design that appeared for the first time last year will be held by a number of potential Taiwanese actresses including Li Kangyi, An Yixuan, Xie Xinying, Chen Yanxi and others this year. In addition to paying tribute to the shortlisted films, it also symbolizes the continuous inheritance of the film’s vitality, and can also bring a slightly relaxed atmosphere to the tense unveiling moment.

Xiaomi eliminated MIUI, but the car was disconnected.

With the official announcement of the Xiaomi 14 series mobile phone conference on October 27, Xiaomi 14 immediately boarded the hot search. In this regard, Lei Jun responded enthusiastically: "Don’t worry, this product is very strong!"

One day later, Lei Jun announced that Xiaomi’s self-developed new operating system Xiaomi 澎湃 OS will be launched soon, and Xiaomi 14 series will be the first mobile phone equipped with the new system, and MIUI, which has served for 13 years, will gradually fade into the dust.

In fact, Xiaomi 澎湃 OS is not only an upgrade and replacement of MIUI, but also a brand-new ecological operating system, and it is also ready for the upcoming car system. As Lei Jun said, this is "a key leap towards" people and cars ".

With the increasing involution of the mobile phone track in recent years, and the mobile phone becoming the connection entrance of intelligent hardware including automobiles and home appliances, the mobile phone with "no volume" in hardware has finally come to the software arena by the express train of the Internet of Things.

Xiaomi has always pursued the development model of "soft and hard combination". Even the first product of Xiaomi is the operating system software like MIUI. Coupled with the self-developed system of Apple and Huawei, "Zhuyu is in the front", Xiaomi really has no reason not to develop its own operating system.

Nowadays, MIUI, which has been with Xiaomi users for 13 years, is about to retire, and the OS, which has been dormant for 9 years, has finally come to the sun, becoming a key hub to help realize the ecological closed loop of Xiaomi’s "people and cars".

At such a critical moment, Xiaomi automobile failed to show up, and the current new energy vehicles have been seriously involved. It is not easy for Lei Jun to realize the ecological closed loop of "people and cars".

As Xiaomi 澎湃 OS takes the stage, MIUI will gradually retire.The operating system developed by Xiaomi twice has different development stages and missions.

Looking back at the birth of MIUI, on August 16th, 2010, MIUI, as the first product of Xiaomi, was officially launched, and it was constantly updated and iterated at the pace of one shift every year. By last December, MIUI had evolved to MIUI 14.

For more than ten years, MIUI has only four commonly used functions from the first edition, and has gradually become the underlying deep framework of cross-end interconnection; The radiation scope of MIUI has also expanded from the earliest 100 "dream sponsors" to 1.175 billion cumulative users worldwide.

The birth of MIUI means that when Xiaomi chose to cut into the market at a low price with a cost-effective advantage in the early stage of its business, it neutralized the low-end and cheap atmosphere when Xiaomi’s hardware equipment was not dominant, adding the charm of quality and making Xiaomi’s mobile phone stand out.

For example, they are all customized systems developed based on Google Android, but MIUI is more beautiful and refreshing, perfectly supports the display of Chinese fonts, and even includes alarm clock functions for the lunar calendar and weekdays.

Even so, MIUI, after all, is a third-party mobile operating system based on the deep optimization, customization and development of the Android system under Xiaomi, so it can’t get rid of the drawbacks of the bloated, stuck and unstable Android system.

At the same time, in the era of Internet of Everything, with the growing ecological chain of Xiaomi, and the release of Xiaomi car is in sight, the complexity and huge number of operating system branches involved in various devices, as well as the ecological connection gap between different systems and protocols, have become challenges that cannot be ignored.

At present, MIUI obviously can’t afford such a large-scale interconnection. The biggest problem caused by all kinds of accumulated disadvantages and inconveniences is to push up the cost of development and maintenance, and even discourage users because of the unsmooth experience.

The birth of Xiaomi 澎湃 OS is precisely to solve this problem. Its goal is to build a unified and extensible operating system framework to support all kinds of smart devices of Xiaomi, thus breaking down the barriers between different devices and different systems.

According to public information, when Xiaomi’s Internet of Things business began to take shape in 2014, Xiaomi had already started exploratory development and verification of the operating system. In 2017, Xiaomi officially started the research and development of a new operating system. And in 2020, it launched an operating system specially built for IoT devices &mdash; &mdash; Xiaomi Vela。

The word Vela comes from the Latin word "sail", which is a "real-time operating system" (RTOS) made by Xiaomi based on the foreign open source project "NuttX". The main target hardware is smart speakers, smart light bulbs, water meters and meters.

With the increasing number of "smart homes" connected by Xiaomi, what Xiaomi Vela has to do is to provide a unified platform for these smart home devices to manage and open up fragmented Internet of Things application scenarios.

Xiaomi 澎湃 OS inherited the Vela system. By "integrating the deeply evolved Android and the self-developed Vela system, it completely rewrote the underlying architecture and made a public base for the future tens of billions of devices and tens of billions of connections."

In other words, Xiaomi 澎湃 OS has carried the mission of the underlying base of the Internet of Everything since its establishment, and it has also become a powerful tool for Xiaomi to solve the current weak growth of the mobile phone market and start new growth with "the whole ecology of people, cars and homes".

A cruel reality in the mobile phone market is that only by expanding outward can we seize the future.On the one hand, Xiaomi makes efforts to build cars and home appliances, and broadens the ecology of Mijia. On the other hand, it deeply integrates them through innovations such as operating systems to stabilize the core position of the mobile phone business.

As the core entrance of the Internet of Everything, mobile phones are deepening the penetration of other business ecosystems of Xiaomi.

In addition to the TV business that was recently merged into Xiaomi’s mobile phone department, in the last three years, Xiaomi also split the notebook business and tablet business and merged them into the mobile phone department; According to many insiders, Xiaomi’s wearing department, which was established in 2020, was previously included in the R&D system of the mobile phone department.

According to Xiaomi insiders: "In the mobile phone ×IoT strategy, the mobile phone is 1, and the others are all behind 0."

On the one hand, mobile phones are still the basic disk of Xiaomi, accounting for more than 50% of revenue for many years; On the other hand, Xiaomi’s mobile phone business is under obvious pressure. The data shows that Xiaomi’s smartphone business revenue in the second quarter was 36.6 billion yuan, down 13.4% year-on-year; In the second quarter, smartphone shipments were 32.9 million units, down 15.8% year-on-year.

Compared with the low speed or even negative growth of mobile phones, Xiaomi’s IoT business has shown greater growth potential.

According to Canayls data, in June 2023, the number of active users of MIUI worldwide reached 606 million, a year-on-year increase of 10.8%; As of June 30, 2023, the number of IoT devices (excluding smartphones, tablets and laptops) connected to Xiaomi’s AIoT platform has increased to 655 million, a year-on-year increase of 24.2%.

Xiaomi started the layout of smart home ecology in the early stage of its business. In 2013, it started the ecological chain plan, and planned to "invest in 100 ecological enterprises in five years", and formed a unique Mijia ecological chain, among which there are many outstanding people in the segmentation field. For example, mi band is the product of cooperation between Xiaomi and Huami. Behind Xiaomi headphones is Wanmo Acoustics, and behind smart homes are enterprises such as Green Rice and Smart Rice.

The aggregated business with rich products and higher competition barriers such as "Family Barrel" has also attracted a number of mobile phone manufacturers.

For example, in recent years, Huawei has successively released many products including watches, tablets, headphones, whole house intelligence, etc. OPPO also started with TV to lay out smart home products, and made rapid progress.

Visible,In recent years, the "involution" of the mobile phone industry has been completely not limited to the mobile phone itself, but in ecology.

Today’s mobile phone camp, the two brands of Apple and Huawei, which are firmly stuck in the high-end market, have their own operating system, and at the same time, they have established the "Apple Family Bucket" and "Huawei Family Bucket" with exclusive applications, services and products.

In a practical sense, the self-developed operating system can not only promote the cause of the Internet of Things, but also help optimize the brand image and win the high-end market. At the same time, through the self-developed operating system to reduce costs and increase efficiency, we will build a moat of technology and services, get rid of dependence on Android, and reduce all aspects of research and development costs and the risk of "stuck neck" sanctions.

Before Xiaomi, Huawei’s HarmonyOS system and Apple’s iOS were worthy of reference. For example, Huawei’s unified naming of "HarmonyOS" made Huawei’s entire ecosystem have a higher degree of recognition, and the self-developed ecosystem extended more exclusive applications, services and products, which not only improved users’ stickiness, but also boosted shipments of other product lines.

Nowadays, the involution of mobile phone manufacturers seems to be concentrated in the operating system, and they all hope to build their own smart terminal "family bucket". The competition faced by Xiaomi is still not small.

In addition, from the perspective of ecological chain, Xiaomi has established a wealth of products and accumulated a huge user base, but in a short time, Xiaomi still can’t get rid of Android.

If you don’t rely on Android AOSP, most applications on Xiaomi devices need to be redone according to your own development requirements, which is unrealistic at present. Even HarmonyOS system has gone through many iterations to achieve independence.

Therefore, Xiaomi can’t pose a direct threat to iOS, Android, HarmonyOS and other ecosystems in the short term just by developing its own operating system.

Whether Xiaomi’s operating system can finally win in the market competition depends on the effect of core functions and experience, which will have to be announced by Lei Jun at the press conference on October 27th.

With the car landing in the Internet of Everything, a differentiated ecosystem in the future may become the core competitiveness of mobile phone manufacturers to strive for cooperation with car companies. butXiaomi’s car-making business, which has attracted much attention for a long time, has gradually become a key link in Xiaomi’s "people and cars" ecology.

In 2021, seeing that the growth of the entire mobile phone market is about to peak, Lei Jun decisively chose to cross the border to build a car. "Smart cars are the current outlet and an indispensable part of the smart ecology in the future. Together with personal mobile devices and home environment, they form a complete smart life scene."

On March 30 of that year, Xiaomi announced that it had officially entered the field of smart electric vehicles. The initial investment is 10 billion yuan, and it is estimated that the investment will be 10 billion dollars in the next 10 years. Lei Jun said, "This is the last major entrepreneurial project in my life. I am willing to put all my reputation in life and personally lead the team to fight for Xiaomi Automobile. "

Two years after it was put into production, it was recently reported that Beijing Yizhuang Xiaomi Automobile Factory had started construction this year, and mass production was imminent. On October 13th, Guo Ming Fufa, an analyst of Tianfeng International Securities, said that the first Xiaomi car is expected to be sold in 2024, with an estimated shipment of 50,000-60,000 units. The key selling points are autonomous driving, software ecology and 800V fast charging and power configuration, and the estimated price is less than 300,000 yuan.

In addition, according to market rumors, Xiaomi’s new car will adopt the 澎湃 OS system, and will be equipped with Qualcomm’s latest flagship chip and wireless charging technology; At the same time, it also supports 800V high-voltage fast charging, charging for 10 minutes and battery life of 300 kilometers.

In terms of autonomous driving, Lei Jun once said that Xiaomi Automobile will enter the first camp of the industry in 2024. Therefore, Xiaomi has formulated the strategy of full-stack self-research, and the automobile R&D team has expanded to 2,300 people in 2022, and has applied for 956 patents as of October 18.

From the perspective of supply chain,The mass production of Xiaomi automobile in 2024 may be just a good time, that is, just avoiding the bottleneck period of the industry, sitting on the sidelines when the major car companies are rolled up and flying, and entering the market when the industry completes the reshuffle.

However, with the popularization of new energy vehicles, the domestic competition market for new energy vehicles has become a red sea. BYD, Ideality and Huawei have occupied the dominant market position, and Tesla, which continues to reduce costs, has great momentum to fight the price war to the end, while Weimar and other automobile manufacturers, which were in the early days, have even ended up in bankruptcy.

Compared with Lei Jun’s announcement to build a car, the retail sales of new energy vehicles in China accounted for only 8.49%, and the market of new energy vehicles is growing and the competition is becoming increasingly fierce. According to the data of China Automobile Association, from January to September 2023, the production and sales of new energy vehicles were 6.313 million and 6.278 million respectively, up by 33.7% and 37.5% respectively, and the market share reached 29.8%.

In such a cruel and saturated market,The most likely way for Xiaomi to succeed is to rely on Xiaomi’s brand awareness and integrate the upstream and downstream of the industrial chain to reduce costs and dislocation competition as much as possible.

Since the official announcement of the car, Xiaomi has invested in the upstream and downstream of the industrial chain in the name of Xiaomi Zhizao Fund, Xiaomi Production and Investment Fund, Shunwei Capital and Xiaomi Private Equity Fund Management, and almost invested in the upstream and downstream of the new energy automobile industry chain.

Through investment, we can establish deeper links with enterprises in the upstream and downstream of the automobile supply chain, which is surprisingly consistent with Xiaomi’s logic of making mobile phones in the past.

Making good use of its own resources in supply chain integration, 6.5 billion loT equipment worldwide, 600 million monthly MIUI users, and tens of thousands of retail stores across the country may be the key to Xiaomi Automobile’s latecomers.

Internet use for minors： from entertainment to entertaining.

　　On February 27th, 2023, the Central Committee of the Communist Party of China and the State Council issued the Overall Layout Plan of Digital China Construction (hereinafter referred to as "the Plan"). The Plan points out that speeding up the construction of digital China is of great significance and far-reaching influence on building a socialist mo dern country and promoting the great rejuvenation of the Chinese nation in an all-round way. The Plan also points out that it is necessary to strengthe n the supply of high-quality online cultural products, guide various platforms and netizens to create and produce positive, healthy and upward-oriented online cultural products, and further promote the digital development of culture and implement the national cultural digital strategy. Teenagers are the vanguard force to realiz e the great rejuvenation of the Chinese nation, the new force to achieve the goal of the second century and build a socialist modern power, and they can’t be absent from the overall layout of the construction of digital China. It is one of the core essentials of the construction of digital China to let minors enjoy the universal and convenient digital culture and get high-quality development in the digital society.

　　According to the "Research Report on Internet Use of Minors in China in 2021" (hereinafter referred to as "Report") issued by the Central Rights and Interests Department of the Communist Youth League and China Internet Information Center, the top five online use behaviors of minors are online learning (88.9%), listening to music (63.0%), playing games (62.3%) and chatting (53.4%). It can be seen that minors mainly use the Internet for learning and entertainment, especially through the Internet. According to the report, nearly 40% of minors learn extracurricular knowledge through the internet, and more than 70% think that the internet is helpful for learning. This shows that the internet use of minors is gradually changing from "toys" to "tools" and from entertainment to knowledge.

　　Karl Mannheim, a German sociologist, believes that knowledge is characterized by openness and mobility in the process of modern society. The knowledge of short video platform broke the kn owledge barrier, changed the linear and self-contained characteristics in the past, and showed the characteristics of networking and knowledge sharing. Through the reorganization and transformation of knowledge, it creates a learning space and platform with diverse contents and rich forms for people, which makes the boundary of knowledge learning in the digital age more extended and integrated, and serves the minors and provides them with an important channel to broaden their horizons and increase their knowledge. The short video is visual, scene-oriented and practical, which is more in line with the cognitive law of minors. Therefore, the Report also shows that nearly half of minors study through short video platforms. Among them, 34.0% are primary school students, 61.8% are junior high school students, 65.1% are senior high school students and 64.7% are secondary vocational school students. It can be seen that the proportion of minors over 12 years o ld who are exposed to short videos is higher. Minors watch short videos of learning knowledge such as exam counseling and classroom knowledge, accounting for nearly 40%, and watch short videos of interest knowledge such as piano, chess, calligraphy and painting, historical geography, sports and dance, and watch short videos of leisure knowledge such as tourism and food, accounting for nearly half. Moreover, short video platforms such as Tik Tok have also become the main channels for minors to expand their cognition.

　　Facing the brand-new learning style of minors in the digital age, how to use short videos scientifically and reasonably has become a new topic for family rearing and school education in the digital age. Some parents worry that their children are addicted to short videos, but psychological research believes that addictive behavior needs six elements: goal, feedback, progress, challenge, suspense and socialization. That is to say, users are more likely to be addicted if there are six elements in the process of using a product: having a goal, getting feedback in time, getting rewards frequently, constantly encountering new challenges, uncertain results and having social attributes. Moreover, whether it is addictive or not is closely related to the user’s living conditions, psychological conditions, interpersonal relationships and family upbringing. Although short videos have increased people’s sensory experience more comprehensively than words or pictures, they also have social and entertainment attributes, but they do not have these six elements at the same time. The shortcomings of the short video platform, which mainly transmits information, in constructing a new field of knowledge learning are mainly the homogenization of content and the diversification of value. Parents, teachers and other adults should help minors to make good use of the knowledge resources of short video platforms, so that children can enjoy high-quality digital culture through entertaining. Short video is rich in content, diverse in forms, strong in story, short and pithy, and it is more convenient to "brush the screen" in free leisure time, so it has also become people’s leisure products. In order to better transform its entertainment into education and fully integrate entertainment and ed ucation, adults need to have high digital literacy.Give more practical help and guidance to minors.

　　Parents and teachers should empower minors and create a digital environment suitable for their development. At the World Digital Education Conference h eld in February 2023, the Ministry of Education issued "Teachers’ Digital Literacy", requiring teachers to make good use of digital education resources to guide students’ learning. Similarly, parents also urgently need to improve their digital literacy, enhance their digital thinking, digital cognition and digital skills, and make good use of the digital cultural resources of the Internet platform with their children to develop a green and intelligent lifestyle. Parents and teachers should pay special attention to the following relationships in order to make children benefit from opening books to opening screens, and from simple entertainment to entertaining:

　　Balance online life and offline life. The development of the Internet has increased the inclusiveness of knowledge and brought new learning experiences and knowledge acquisition channels to children. Parents and teachers should pay special attention to guiding children to balance online life and offli ne life. We should not only pay attention to enriching children’s online life, so that children can live a quality digital life, but also pay attention to children’s offline leisure, social, family life and campus life, so that children can have a healthy and positive offline life, which is more conducive to children’s online life and offline practice.

　　Balance entertainment and education. Knowledge in the visual and interesting packaging of short videos makes children feel more interesting and easier to learn. However, in the eyes of many parents and teachers, they always feel "unlike" learning, because in the eyes of adults, they should "learn from the sea and work hard." As the children of the Internet aborigines, it seems that fun is the last word. Parents and teachers should pay attention to balance the relationship between the two, not only to meet the needs of the network generation for learning change, so that children can gain a sense of participation and belonging in their studies, but also to increase education in entertainment, so that children will not get lost in the network in joy, thus dispelling the "heavy feeling" of learning.

　　Balance short and systematic. Shortness is both an advantage and a disadvantage of short video. Short knowledge is more convenient for students to watc h and more suitable for children’s short attention time. However, learning knowledge also needs to be systematized, so as to avoid "the blind touch the elephant". Parents and teachers should make good use of their advantages, and at the same time, they should consciously guide their children to build the knowledge system they need, and conduct multi-dimensional and multi-level discussions around a certain topic and a certain kind of problems, so that children can overcome the problems brought by short video learning.

　　Balance child practice and child protection. The barrage, comments and live broadcast of short videos are more interactive, which is also a "double-edged sword". The advantage is that children have more opportunities to participate, think and interact when learning online, but the problem is that it may also bring risks to minors. Therefore, we should not only encourage minors to participate in more practice, but also do a good job in protecting the rights and interests of minors. In particular, parents and teachers need to enhance their awareness of child protection, improve their digital literacy and that of minors, so that every child can enjoy the fun of knowledge learning.
