Unlike McDonald’s high-profile packaging of China stores for sale, KFC, another iconic American fast food chain giant, unexpectedly sold its China business in a low-key manner. The night before yesterday, Yum! Brands, the parent companies of KFC and Pizza Hut and listed on the new york Stock Exchange, announced that Yum! China would be separated from Yum! Brands and listed on the NYSE as an independent company. At the same time, after the spin-off, Yum! China will receive a total investment of US$ 460 million from Chunhua Capital and Ant Financial. This means that Yum! Brands has sold part of its operations in KFC and Pizza Hut in China to two purchasers from China.

　　Yum!’ s business in China has fallen into a trough?

　　In fact, Yum! Brands has already paved the way for China business. Last October, it announced that it planned to split Yum! Brands and Yum! China, and this transaction was carried out on the basis of that split at that time.

　　KFC is the first American fast food chain brand to enter the mainland market in China. In 1987, it opened its first store in Qianmen, then the most prosperous business district in Beijing. At that time, it was fashionable for both Beijingers and foreign tourists to queue up for a fried chicken or a hamburger at KFC. And KFC’s rule of "throw away the food after it has been sold for 90 minutes" brought from the United States has also attracted the attention of consumers in China. It is likely that KFC’s great success in exploring the China market attracted McDonald’s. Subsequently, McDonald’s also entered the mainland market of China in 1990. For a long time after that, these two brands were the iconic brands of American fast food culture in China.

　　In 2015, China accounted for half of the global business of Yum! Brands. However, this data can’t hide its downward trend in the China market. Since the incident that Shanghai Fuxi reprocessed expired meat raw materials and changed the shelf life and supplied them to McDonald’s and KFC restaurants in July 2014, KFC’s single-store income began to decline continuously. Yum! China’s same-store sales fell by 16% in the third quarter of 2014, and almost all of them fell by double digits in the following three quarters. Parkson’s financial report for the second quarter of this year, just released in July this year, shows that the same-store sales of KFC in China increased by 2% year-on-year, but it actually climbed slowly from the low base of last year’s lowest valley. During the same period, the same-store sales of Pizza Hut in China shrank by 11%. Therefore, it is widely analyzed that the reason why foreign shareholders strongly demand Yum! Brands to spin off its business in China has something to do with the poor prospect.

　　The "China Golden Period" of franchising may have passed.

　　Franchising is an effective way for KFC to expand its business in the world. As early as 1993, it began to carry out franchising in China, and since 2000, it has only adopted the franchising mode of "not starting from scratch" in China. The so-called "not starting from scratch" means that KFC will hand over a mature and profitable restaurant to its franchisees. In this way, franchisees can put all their energy into the operation and management of stores without having to make preliminary preparations such as site selection, opening stores, recruiting and training employees. This greatly reduces the business risks of KFC franchisees. In the words of Su Jingshi, former president of Yum! China Restaurant Group Greater China, "franchisees can succeed only by maintaining." By this means, KFC has achieved rapid expansion in China, and the number of stores has reached nearly 5,000 by the end of last year.

　　However, KFC has set a high threshold for joining, and the transfer fee for each restaurant is as high as 8 million yuan. After that, the going-concern expenses include the franchise fee accounting for 6% of the sales and the advertising sharing fee accounting for 5% of the sales, and the first agreement is signed for at least ten years. At this point, McDonald’s joining in China is exactly the same, and even the joining fee and cost-sharing ratio are exactly the same. This is obviously not a simple imitation of who, but a careful calculation based on a rigorous business model.

　　In fact, no matter KFC or McDonald’s, its investment in the global business chain is more than the catering service itself, that is, it operates the store in a benign state by selecting a location. As can be seen from the income structure of the two catering giants, this part of the profits is far greater than their own stores. With KFC and McDonald’s reaching the scale of thousands of stores in China and gradually covering third-and fourth-tier cities, the blank market space in the future is getting smaller and smaller, and the golden period of realizing profits through joining and transferring has passed. Therefore, it may be the best time for them to "pack up and sell" their business in China.

　　Although the supply of raw materials, as well as the annual brand use and marketing promotion expenses exceeding 10% of sales are still the long-term benefits they can enjoy, it is obviously only a decimal for them. Moreover, with the increasingly fierce competition in the catering market in China, the future sales potential of these foreign fast foods is not clear.

　　The receiver may want to change the joining mode and continue to expand.

　　Judging from the current Chinese takers of foreign fast food, whether it is Chunhua Capital or Ant Financial, or BTG, Sanpower and Sinochem, which are interested in bidding for McDonald’s China business, their real intention is probably not to directly participate in the catering industry, but to graft their current business to achieve profits in a new expansion mode.

　　This can be seen from the caliber of Ant Financial. "Ant Financial will help Yum! China provide mobile payment services for its brands, including Alipay platform." In fact, although the online speculation of Ma Yun "finally achieved revenge for not being hired by KFC that year", in fact, Ma Yun is definitely a supporting role in this investment — — His total investment with Hu Zuliu of Chunhua Capital will only account for a few percent of Parkson China in the future. Even compared with Hu Zuliu, the $50 million invested by Ma Yun is too small, accounting for only a fraction of the total investment of $460 million.

　　In fact, it can be seen from the fact that no real catering enterprise is willing to take over the business of KFC and McDonald’s in China that these two brands are more tools for the industry, which may also indicate that their future development in China will not be too exciting. Even some people in the industry believe that China KFC and McDonald’s, which have been abandoned by their parent companies, may embark on a development path in China that is divorced from stores in other countries in the world.

　　I don’t know if it is the first move to merge into Ali. The Beijing Youth Daily reporter learned that KFC will officially enter Tmall on September 6. In the future, consumers can buy electronic coupons for KFC food in Tmall stores and then exchange them for corresponding foods in physical stores.

　　Financial observation

　　Kfcs are "old"?

　　Although in many countries, KFC and McDonald’s are still regarded as the representatives of American fast food industry and even the symbols of American consumer culture, in fact, in the United States, more and more people have begun to diversify their choices, especially the opportunities for the younger generation of Americans to enter KFC are decreasing.

　　In the first half of the year, the only cross-industry economic indicator of customer satisfaction in the United States, the American Customer Satisfaction Index, released the 2016 Restaurant Satisfaction Survey Report. It shows that the average satisfaction score of fast food restaurants in the United States this year is 79, but the scores of KFC and Pizza Hut under Yum! are below the average. McDonald’s ranked at the bottom of many participating fast food chain stores with a score of 69 points, and McDonald’s ranked at the bottom last year.

　　As for the poor performance of KFC and McDonald’s, some American businessmen believe that although this does not mean that the food quality of KFC and McDonald’s has declined, they are "really old" in the eyes of American consumers and can no longer be the most typical representative of American fast food culture.

　　In fact, in the China market, KFC and McDonald’s are also facing the same problem. With a new generation of young people becoming the main force of fast food consumption, McDonald’s and KFC are no longer their absolute first choice to experience foreign fast food, and a large number of other brands of fast food subdivide the China market. More crucially, no matter how the varieties cater to the taste of China population, the standard fried chicken, French fries, hamburgers and coke that KFC and McDonald’s take care of have become the global representatives of "junk food". More and more young families in China have kept their children away from such fast food restaurants, at least in first-and second-tier cities.

　　For KFC and McDonald’s in China, the aura of standardization and trustworthiness that they were most proud of in the past has also been shattered with repeated food safety incidents. No matter Sudan red or fast-growing chicken, and then to the Shanghai Fuxi incident, these foreign fast foods have not been able to stay out of it.

Original SME SME technology story

Teenager, are you eager for strength? Want to be a hypnotist? Now all you need is a chicken, and hypnosis can be done quickly.

First, hold the chicken tightly so that its head is down and its beak is on the ground, and then draw a trace on the ground with chalk or fingers. Wait until the chicken is quiet and then let go of your hand, and you will get a new "stupefied chicken"

A "hypnotized" chicken

Of course, this is not true hypnosis, it uses the fear instinct of animals in the face of threats. Your fierce operation made it mistakenly think that a predator was close at hand, so it fell into a state of suspended animation (Thanatosis).

Hamiton Bertie Gibson, a British psychologist, mentioned in his book that the ultimate record of the longest time a chicken was hypnotized was 3 hours and 47 minutes.

In 1646, the German scholar Athanasius Kircher observed a chicken that went into suspended animation because of fear.

There are many animals that play dead in nature, and it also has a proper term called "tonic immobility".

This is a defensive strategy, which widely exists in mammals, birds, reptiles, fish and insects, and the "death method" is even more varied.

The 5-year-old girl in the CCTV program "Challenge Impossible" has "hypnotized" (scared) dogs, lizards, chickens, frogs and spiders, and was madly spit out.

It is precisely because suspended animation is so common that a number of so-called animal "hypnotists" have been made. They made a simple animal instinct magical and full of mystery.

There is a big brother who started a chicken farm, and even sold the local chicken at twice the price of the local market by the marketing method of "hypnotizing chicken". And those who buy chickens are really uneducated.

When confronted with a potential threat, two signals will immediately appear in an animal’s mind-"fight" or "flight", also called Fight-or-flight response. This is like the degree to which the brain has written, and you will choose between them, so that the body will respond quickly to better protect itself.

But in fact, in the case of "fighting" but not "escaping", our bodies can still fall into the third state-freeze.

Fight, flight and freeze displayed by Lego villains

When being touched at close range or feeling attacked, the rigidity of the prey may be triggered. But this state is not a decision made after careful consideration, but an involuntary defense mechanism.

They are really stiff and unable to move as if they had been acupoints. However, his brain is still spinning rapidly, and he is also alert to the changes in the surrounding environment.

On the surface, this rabbit enjoys the shower, but in fact, it has entered a state of suspended animation because of fear. Rabbits are prone to stress reactions and blind bathing is not recommended.

In fact, in the face of great pressure and threats, human beings will also have similar tonic static reactions. Have you ever tried, because you are too nervous, standing on the podium with your head blank and you can’t say a word?

In addition, when human beings are infringed, they often have temporary paralysis. Some researchers have talked with 300 women who have been sexually assaulted and found that 70% of them experienced obvious rigidity and stillness when they were attacked. They will be paralyzed, unable to scream, unable to resist, and their bodies will be completely out of control. Similarly, soldiers who have been on the battlefield have also had similar experiences.

It’s just that there are many mysteries about animal suspended animation. Because the matter of animals pretending to be dead is quite strange and full of doubts.

An animal faking its death is like taking its own life as a gamble. The success or failure of this gamble depends entirely on the foraging mode of hunters.

Fake dead frog

First of all, it is difficult to know whether the hunter will lose interest in the dead individual by pretending to be dead. If suspended animation can’t make hunters lose interest, then the poor guy who wants to get away with it by suspended animation will miss the best chance to escape. On the contrary, it makes the hunting work easier for hunters, and if they are not careful, they will directly change from "suspended animation" to "real death".

Moreover, the state of suspended animation can not reduce the sensory ability of predators to locate or identify prey, and it can not enhance the resistance of prey when attacked. Many times, this kind of rigidity and stillness will remain for a while, and the risk of being eaten seems to be even greater.

Fake dead bird

However, judging from the results of evolution, the strategy of feigning death is still useful with a high probability, and the overall advantages outweigh the disadvantages. If some predators delay eating, are not interested in dead things, and even find it difficult to distinguish still things, then the prey may escape.

In fact, obedience can really hurt yourself less. The state of rigidity and stillness can inhibit the further attack of predators and reduce the action of hunters to subdue their prey.

For another example, many top hunters will be more interested in the prey that is fleeing around, such as your cat, and the favorite is the cat-teasing stick full of soul. If the cat comes after a group of mice, and if all the other mice are running away, then the little mouse who is scared and unable to move is more likely to survive.

Similarly, most cases of feigning death belong to the "last desperate attempt", and it is an effective strategy to wait for hunters to relax their vigilance and find opportunities to escape. And fake death. Maybe it can really make some animals get to the end.

In nature, the best acting is the North American opossum (Didelphis Virginia), which deserves an Oscar in the animal kingdom.

It’s really not dead.

The North American opossum is the only marsupial living in North America. On the American continent about 70 million years ago, marsupial companions of opossums survived.

Only later, due to the rise of carnivores and other reasons, these marsupials with little resistance became extinct and went to the end. Only the opossum shoulders the fate of the whole marsupial, and survives tenaciously on the American continent, dealing with top hunters such as red fox, wolf, jaguar and short-tailed cat.

But it is in this case that the number of opossums in North America is still increasing. Among them, knowing how to play dead is a great knowledge and advantage for their survival.

The possum playing dead in Ice Age

Although the population of opossum in North America is huge, they are properly located at the "low end of the food chain", and almost any animal larger than it is a natural enemy. Therefore, opossums can only lie in the daytime and go out at night, and live by preying on insects, snails, birds, and occasionally eat some plants. In addition, the North American opossum moving on the ground without the shelter of trees is also clumsy and has poor defense ability.

When chased by the enemy to the end of the road, they will fall to the ground with a thud and enter a state of suspended animation-eyes closed, mouth slightly open, uvula spit out, belly swelled, tail drooping and winding in a circle, motionless.

When the dog comes, he can only pretend to be a dead opossum.

In order to be more realistic, the North American opossum will tremble slightly when it falls down, and its breathing and heart rate will slow down and its body temperature will drop while shivering. In addition, the glands near their anus will secrete a foul yellow-green mucus, which tastes like a highly corrupt corpse. If I don’t know, I really think it has been dead for three days and nights, and the body stinks. And this can often deter hunters and make it difficult to swallow.

It is precisely because of the grandiose acting skills of the North American opossum that people have specially invented a word "play possum" to describe the behavior of some people who pretend to be deaf and deaf.

Playing dead pig nose snake

Similar to the possum’s way of playing dead, there is also a pig-nosed snake. When encountering a hunter, the pig-nosed snake will bluff first, spread its neck ribs and make a horrible hiss, just like being possessed by a cobra.

But when bluffing doesn’t work, they will decisively enter the suspended animation mode, with their bellies turned up, their mouths opened to spit out the letter, and even oozing blood drops. The pig-nosed snake, like the opossum, also carries its own chemical weapons, which will give off an extremely unpleasant smell and very dissuade it.

Therefore, animals’ suspended animation is not simply lying on the ground, but they will also make themselves more difficult to swallow through various strategies.

What is even more surprising is that some animals in nature have learned to use the "rigidity and stillness" of other animals to hunt.

Whether in the wild, in captivity or in the laboratory, humans have long discovered that sharks, the top hunters, can also fake their deaths.

Turning the shark over and stimulating the skin around its nose may trigger the shark’s suspended animation for up to 15 minutes. Using shark’s suspended animation can also make researchers reduce the shark’s struggle and reduce the probability of injury to both sides when subduing sharks.

However, some people think that this rigidity and stillness of sharks is not due to fear, but related to reproduction. Studies have shown that after obtaining the mating right of the female, the male will also turn over the female body to cause rigidity and stillness, thus making the whole mating process smoother and easier.

But in any case, killer whales with IQ of off the charts seem to have seen through everything, and have learned to kill sharks by faking their deaths.

When encountering a shark, killer whales don’t rush to fight, but rush over and knock it over, biting the shark with their mouths so that it can enter a state of rigidity and stillness.

In 1997, someone photographed this precious picture of killer whales "outwitting" great white sharks off the coast of California, USA. Sharks in this state easily become the lunch of killer whales. Another example of killer whales "hypnotizing" their prey took place in New Zealand, and the victim was a stingray.

Fight scene in 1997

It can be seen that playing dead is really not omnipotent, and the "final interpretation right" is still in the hands of hunters. Finally, by the way, it is really useless to "pretend to be dead" when you meet a bear in the wild. If you meet a bear who has been hungry or sick, pretending to be dead is equivalent to sending a lunch box directly.

Special feature of 1905 film network It tells the story that four high school students with different personalities accidentally crossed into the game world and turned into game characters. In the dangerous tropical jungle of Yumanji, several people became Dr. Yong Shi, Maozi Fenba, Professor oberon and Ruby with Iron Fist respectively. Faced with the attack of jungle beasts and the pursuit of evil forces, the four must work together to overcome many crises and win the game in order to get a chance to return to reality.

This week’s movie channel "A Good Movie with a Date" column, let’s follow the footsteps of several brave people and experience the jungle adventure together in "The Game of the Brave: The Battle of the Jungle"!

Classic IP innovation restart

Before The Game of the Brave: The Battle of the Jungle, there were actually two movies of The Game of the Brave. The first one that we are most familiar with was released in 1995. At that time, as one of the ten imported blockbusters in 1996, the film was released in China and became the collective memory of a generation.

Twenty-two years later, the story of "The Brave Game: The Battle of the Jungle" continued the end of the first film, so why did this series of movies have such strong vitality?

In 1981, Chris Van Olsberg, an American children’s literature writer, finished drawing this book. At first, the book contained only 32 pages and 14 illustrations, but it won the title of Oscar in the picture book industry the following year for its imaginative ideas. — Kadik Award.

With the foundation of the story, The Brave Game was successful because a very suitable hero was selected at that time.

The Brave Game starring robin williams reminds fans of Yumanji. In 2014, Williams, known as a comedy master, chose to leave this world because of depression, and we can never see his return in this series. However, Game of the Brave: Battle of the Jungle chose a very suitable candidate to take over Williams.

The formation of megaliths

Childhood Qiang Sen was ugly and even a little thin, and he couldn’t see the big guy in the future at all. That’s because Qiang Sen’s family was very poor for a long time, and his father who fought in the American professional wrestling league couldn’t bring a stable income to this family. At the age of 16, Qiang Sen was so poor that he was only $7 from his apartment to the street. At that time, his life turned around, and he became Dwayne Douglas Johnson today with two choices.

The first choice comes from: wrestling　

After entering high school, Qiang Sen gradually showed his athletic talent. He hoped that his son would follow in his father’s footsteps and engage in wrestling. At first, his father firmly opposed it. He didn’t want his son to live a precarious life like him in the future, but Qiang Sen was very determined. He insisted on getting up at 4 am every day for training. In the end, he not only gained recognition, but also won eight American professional wrestling league championships under his father’s training.

The second choice comes from: movies.

Qiang Sen’s strong acting talent and body language have attracted a lot of media attention, as well as from film companies. So in 2001, at the age of 29, he chose to appear in the first film of his life and became a film actor.

The return of the mummy movie clip

In recent years, when he gradually became the highest-paid actor in the world, he chose to name his film company "7 dollars". He said, "It is really surprising to become the highest-paid actor. I don’t have a high degree from Harvard University, but with my failure, I have made continuous progress, and I will never forget those experiences."

In 2016, Qiang Sen and his $7 film company participated in the first project, The Brave Game: The Battle of the Jungle. He not only starred in the film, but also assumed the role of producer. Therefore, we can see in the film that under his arrangement, the crew went deep into the Hawaiian rainforest to shoot and successfully created the Yumanji world full of beasts.

Special feature of 1905 film network　China art cinema has experienced a long development, from breaking the curse of box office failure of award-winning literary films in 2014 to shining brilliantly at this year’s Golden Rooster Award in China, literary films are welcoming new development opportunities. Today, Film Critics Today invited Shadan, a film critic who has been planning and screening in art cinema for a long time, to discuss with us the charm of art cinema.

According to incomplete statistics, 20-to 29-year-olds account for 60% of the total audience. More young people like literary films, and there are more controversies and labels surrounding it. Next, we will enter the quick question and answer session to see if you have the same misunderstanding about literary films.

Compared with other types of films, literary films have different missions and values. Professor Yin Hong of Tsinghua University once said: "Literary films focus on conveying the creator’s concern for human nature, society and history." Literary films are a very important part of the film industry, which plays a very important role in the cultivation of directors and audiences. In the early works of China’s fifth-generation directors, there are many films called literary film models, such as Harmony, which won many international awards that year. Thanks to the cultivation and cultivation at that time, today’s two movie master came into being. Art cinema’s creation nourishes young directors. Many young directors started with filming little art cinema, and they will become the main force of China films in the future. art cinema is a very important starting point in their lives.

At the same time, the existence of art cinema also ensures the diversity of big-screen movies. It is impossible for cinemas to have only popcorn blockbusters, but there should also be art cinema. Art cinema, as a very important cultural form, can provide many ideological sources for the audience and enhance their artistic aesthetic ability.

Art cinema should not be associated with box office failure. This year’s Golden Rooster Award-winning film "Mom! Is a very typical art cinema, and the box office performance is not bad. Shadan said: "In fact, we should not link this literary film with this box office failure. There is actually a big problem in this, that is to say, who are you going to film for? We also suggest that many young creators not only shoot some of their own stories, but also embrace the audience very enthusiastically and tell your story in a way that resonates with the public. "

In today’s Internet age, talented creators will not be buried, and there will be a large number of film selectors, curators and film critics to support them. art cinema, which is often shown in China Film Archive, is popular with audiences. Although these directors are shooting low-cost films, they have formed a very good reputation and brand among the audience.

@ Moderator Xiaoli:Then can you recall some wonderful clips, even those that may be controversial?

@ Shadan:For example, this movie is a very controversial movie, and its box office is very high, but many people (think) that its high level is achieved through the concept of "one kiss for the New Year" in commercial publicity and marketing. In fact, it is not a simple story about love, but a visual system made of a very complicated audio-visual language. The first scene of the movie is a very meaningful scene. A delicate hand actually carries a watch in his hand, telling you that at this moment, this man fell in love with me after being caught in my hand, and he will never forget me for the rest of his life. In fact, he has presented this very mysterious tone in this movie to everyone. In fact, there are more real meanings in movies than we imagined, so I think this is also a very important charm of art cinema, which is that you can keep pondering and watching, and every time you watch it, you will find something very fresh.

"If the racket falls, if it stops, then we will fall."

"Maybe it can fly."

In recent years, more and more successful cases have proved to us that as long as the film itself is good enough, it can always stand out. At last year’s Art Film Promotion Forum, Li Jie, president of Taobao Film, shared data: At present, Beijing and Shanghai occupy 70% of the box office in art cinema, China, and the proportion of Chengdu, Hangzhou, Shenzhen and Guangzhou is gradually increasing. This also shows that art cinema’s prospects and space are enormous.

@ Shadan:Many film festivals in Beijing and Shanghai are always hard to get a ticket, among which the ticket buyers are basically young people, and most of them are women. Women account for more than 65% of the ticket-grabbing links in the whole film festival. These audiences are all potential audiences of literary films. I am also thinking that if we can continuously establish this point-and-line national art film promotion network, we can find a lot of accurate audiences and cultivate them.

I believe this promotion mode will also promote our film creators to create more and better films. I also hope that this promotion mode should be promoted not only in Beijing and Shanghai, but also in more important cities across the country, so that the fire in art cinema can start a prairie fire and we look forward to a new spring in art cinema, China.

A hundred long tables

Thousands of old Chengdu hotpot are composed together.

Changlongzhuang hotpot park

Citizens and tourists enjoy a hot pot feast here.

……

Mid-Autumn National Day holiday this year

"Thousands of people in a thousand pots-Long banquet of hot pot in the park"

First presented in Xibo North Square!

"There is a leisurely and comfortable courtyard dam hot pot, a spicy taste of Chengdu, and a lively atmosphere of a long banquet." Mr. Liu, a citizen, commented on the beef at the hot pot long banquet.

It is understood that this hot pot banquet takes the form of a single person and a single pot, with a total of more than 1,000 mouths, which can be used by more than 10,000 diners to experience authentic flavor on the spot.

There are five parts: tasting area, operation area, food area, shared dining area and performance area. Among them, the food area not only focuses on displaying fresh food, but also allows tourists to pick up food by themselves.

How to rinse the hot pot with the best taste? The chef of beef omasum hot pot in Qingbaijiang Slaughterhouse showed the tourists the technique of "seven ups and eight downs". "To taste the best taste, first iron the beef omasum, and the beef omasum will not leave the chopsticks for more than 8 seconds." The chef of Chongqing hot pot is ready for the diners who pursue spicy degree. "Three kinds of peppers are used in the bottom material, and the taste level is richer."

In terms of the cost performance of hot pot that the public cares about, it is understood that the Black Dragon Beach Deep Water Fish Hot Pot has launched a 38 yuan/person set meal, which includes the bottom of the pot, oil dish, diced yellow pepper, etc. The single set meal in 50 yuan of Qingbaijiang Slaughterhouse contains thousands of layers of shredded beef omasum, flaming beef, piranha and other classic dishes for hotpot. According to reports, this activity will present the hot pot dragon feast for the majority of diners and citizens in accordance with the activity strategy of excellent quality, people-friendly price, gathering popularity and creating vitality.

Hot pot has the characteristics of extensive participation, diverse styles and good interactive atmosphere. The chef of Dalhan grassland mutton hot pot enthusiastically introduced the way to eat mutton with special sesame sauce. "Instant mutton with radish and white tofu is the original flavor of Inner Mongolia prairie." He believes that instant-boiled mutton hot pot is loved by diners in Chengdu, which is also the embodiment of the city’s inclusiveness.

Not only local residents, but also tourists who come to Xibocheng to rinse hot pot and overseas friends. "Thai students who come to experience the taste of Chengdu like this braised tiger skin chicken feet best, and they also say that they want to bring delicious food back to their hometown." The proprietress of pot-stewed hot pot said.

Chengdu is a world-renowned international food capital. If you want to find a kind of most representative food, it is undoubtedly a hot and spicy hot pot. This city-wide food carnival of "thousands of people and thousands of pots" provides a brand-new hot pot food experience and holiday punching destination for diners and citizens, and further polishes the signboard of the international food capital while offering gifts for the National Day.

This long hot pot banquet coincides with the 20th Chengdu International Food Festival and is open to the general public from 11: 00 to 22: 00 every day from September 28th to October 6th.

It is understood that the food festival links the major food activities in the city and forms a global consumption linkage system. Focusing on the theme of "the city of food is full of weather", we will hold professional exhibitions of food, round tables of the city of food, and the 20th anniversary of Chengdu’s "Rongyao" food, presenting Chengdu’s food style in a multi-level and multi-dimensional way, and displaying the image of Chengdu with modern and colorful Chinese style. Simultaneously with the hot pot banquet, there is also the "Xunwei Tianfu" food market, which provides special snacks such as electric barbecue, fried skewers, bell dumplings and stinky tofu, as well as live performances in Mahua FunAge and unplugged music.

　　　　Hepatitis B is one of the infectious diseases with the highest incidence rate in China, and its mortality rate ranks among the top three reported infectious diseases in China. There are about 120 million hepatitis B virus carriers in China. The annual direct medical expenses for liver diseases in China are as high as more than 100 billion yuan. The incidence of hepatitis B in our province is also on the rise, and the incidence of hepatitis B is higher than the national average. The epidemic of hepatitis B is seriously endangering public health. Hepatitis B can be prevented, but the public doesn’t know enough about it. Therefore, it has become the unshirkable responsibility of the whole society to popularize the knowledge of hepatitis B prevention and improve their self-care awareness and self-protection ability.

　　　　How big is the source of hepatitis B infection in China?

　　　　On September 3, the reporter learned from the Provincial Center for Disease Control and Prevention (hereinafter referred to as the "Provincial Center for Disease Control and Prevention") that China has a large population and is a high-prevalence area of hepatitis B (hereinafter referred to as "hepatitis B"), and about 120 million people are carriers of hepatitis B virus. Among the hepatitis B virus carriers, about 20 million to 30 million people are chronic hepatitis B patients. Every year, about 300,000 people die from liver diseases related to hepatitis B virus infection, such as severe hepatitis, cirrhosis and hepatocellular carcinoma. In recent years, the incidence of hepatitis B in our province has also shown a gradual upward trend, and the incidence of hepatitis B is higher than the national average. From January to July this year alone, the incidence of hepatitis B ranked first in the number of legally reported infectious diseases in our province. From January to July this year, the incidence of hepatitis B in the province was 1248 cases, 785 cases, 1423 cases, 1225 cases, 1205 cases, 1237 cases and 1393 cases respectively.

　　　　According to experts from the Provincial Center for Disease Control and Prevention, the source of infection of hepatitis B virus mainly comes from acute and chronic hepatitis B patients and hepatitis B virus carriers. Hepatitis B virus mainly propagates in human liver cells. Hepatitis B virus is also propagated in other organs and tissues of human body, such as endothelial cells, kidneys, white blood cells, pancreas, muscles and germ cells (referring to sperm) on the inner surface of small blood vessels, and a small amount of hepatitis B virus is found in muscles (smooth muscles) on intestines. Therefore, hepatitis B patients and hepatitis B virus carriers can’t supply blood, and their organs are not suitable for donation after death, because their organs all carry hepatitis B virus.

　　　　The expert went on to say that the main ways of hepatitis B transmission include blood transmission, mother-to-child transmission and sexual transmission. Once hepatitis B virus enters the damaged skin mucosa, it can cause new infection. Mothers who are carriers of hepatitis B virus or patients with acute or chronic hepatitis B can spread to their own children in the fetal period, perinatal period and infancy. Experts estimate that 30%-40% of hepatitis B virus carriers in China originate from the spread of such mothers. This infection is very dangerous and serious. Because 90% of infected people can become hepatitis B virus carriers. The relationship between hepatitis B virus and liver cancer is very close, especially familial liver cancer is mostly related to hepatitis B virus infection. The mother is a carrier of hepatitis B virus, and most of her children are infected in childhood and become carriers of hepatitis B virus. It takes about 30-50 years for hepatitis B virus carriers to develop into liver cancer. Once infants and young children are infected with hepatitis B virus, they will become the main population with liver cancer in the future. Therefore, the first dose of hepatitis B vaccine must be given to the baby within 24 hours after birth in order to effectively block the infection of hepatitis B virus.

　　　　What are the clinical symptoms of hepatitis B?

　　　　According to experts from the provincial CDC, the average incubation period of hepatitis B is 6 weeks, but it may be as long as 6 months. Children are often asymptomatic after infection. But compared with adults, most children can become carriers of hepatitis B virus. Symptomatic hepatitis B patients will feel weak, have stomach upset and other flu-like symptoms, and also have dark urine color or grayish white feces, common jaundice (yellow skin or yellow sclera), and the symptoms can last for weeks or months. Most adults can fully recover from acute hepatitis B virus infection, but many children will become hepatitis B virus carriers. Patients with acute hepatitis B have lifelong immunity to the disease after rehabilitation (without becoming chronic carriers). If there are unexplained symptoms such as burnout, fatigue, loss of appetite, liver pain, hepatomegaly, tapping pain in liver area, jaundice, dark urine color, etc., liver disease examination and hepatitis B serological test should be done.

　　　　How to prevent hepatitis B

　　　　According to experts from the provincial CDC, two measures can be taken to prevent hepatitis B? Don’t use blood and blood products that haven’t been tested for hepatitis B in life and collective environment as much as possible, don’t go to black dens to donate blood, don’t have homosexual behavior and whoring behavior, don’t use unclean syringes, acupuncture needles, dental drills and endoscopes and other interventional medical instruments, and don’t share razors, ear needles, tattoo needles, toothbrushes and other instruments. In addition, it is to inoculate hepatitis B vaccine to improve its own immune antibody level.

　　　　Hepatitis B vaccine is suitable for all people.

　　　　Who is suitable for hepatitis B vaccination? According to experts from the provincial CDC, hepatitis B vaccine is also the only vaccine that can prevent liver cancer. Vaccination of hepatitis B vaccine is the core strategy to prevent hepatitis B. In addition to neonatal immunization, preschool children, adults and high-risk groups of hepatitis B should be vaccinated with hepatitis B vaccine.

　　　　He said that the first group of people is newborns, which is the most important group to receive hepatitis B vaccine immunization. Because if you are infected by hepatitis B virus during this period, 90% of you can become asymptomatic infected and hepatitis B virus carriers, and the consequences are very serious. 30% of liver cancer related to hepatitis B virus infection comes from hepatitis B virus infection in newborns, and a large proportion of them develop into chronic hepatitis. Therefore, neonatal immunization is the most important thing to prevent hepatitis B. Since 2003, our government has provided free hepatitis B vaccine for newborns, and stipulated that all newborns must receive hepatitis B vaccine immunization, which is the right of children and the obligation of parents.

　　　　The second group of people are children under 6 years old. Infants infected with hepatitis B are easy to become carriers of hepatitis B virus. The younger the infection age, the greater the probability of persistent infection. After such children are infected with hepatitis B virus, 30%-70% of them can also become carriers of hepatitis B virus, and they will easily develop into chronic hepatitis, cirrhosis and liver cancer in adulthood.

　　　　The third group of people are doctors, especially doctors in surgery, obstetrics and gynecology, dentistry and otolaryngology, laboratory workers engaged in serum testing and all nurses. Anyone who has not been infected with hepatitis B virus should be vaccinated. Besides protecting yourself, it can also protect the safety of patients. In addition, if there are hepatitis B patients or hepatitis B virus carriers at home, their family members should be vaccinated against hepatitis B to avoid infection.

　　　　The fourth group of people are those who are engaged in heavy physical labor and are easy to cause labor injuries.

　　　　The fifth group of people is people with low immune function. For example, after tumor surgery, people who take immunosuppressive drugs for a long time, renal dialysis patients, and blood patients who often need blood transfusion and blood products are in poor health and have low resistance. Once they are infected with hepatitis B virus, the consequences are very serious, so they should be vaccinated with high doses of hepatitis B vaccine.

　　　　The sixth group of people are the army, college students of certain majors, etc. However, there are also some people who can’t get hepatitis B vaccine and don’t need it. If a person with a fever can’t be vaccinated, wait until his fever has gone down. Secondly, people with allergies, that is, people who are allergic to many things should use hepatitis B vaccine with caution. There are already protective antibodies in the body, and people with high levels do not need to be immunized again. However, if the antibody level is very low, it is still a suitable target for vaccine immunization.

　　　　Three needles, protect the child’s life!

　　　　On September 3rd, the reporter learned that according to the actual situation in our province, the Provincial Health Department, in cooperation with the China Hepatitis Prevention and Treatment Foundation, will give free hepatitis B vaccine to 500,000 school-age children in Haidong, Haixi and Yushu from September this year to May next year, so that more than 95% of school-age children in primary schools in the province can get free hepatitis B vaccination, thus making Qinghai one of the provinces that have completed hepatitis B vaccination for school-age children nationwide. Therefore, experts from relevant departments in our province especially remind the public that hepatitis B can evolve into chronic hepatitis, cirrhosis and liver cancer, and hepatitis B vaccine can indirectly prevent liver cancer. Therefore, after three shots of hepatitis B vaccine are given in newborns and childhood, chronic hepatitis, liver cirrhosis and liver cancer can be prevented. After the child is born, he should be given three injections according to the procedure of 0, 1 and 6 months stipulated by the national immunization plan, that is, the first injection should be given within 24 hours after birth, the second injection should be given at one month and the third injection should be given at six months. Adults and children can be vaccinated according to the procedures of 0, 1 and 6 months, which can protect you and your child’s life. (Author: Wang Xiaohong)

　　The State Council Joint Prevention and Control Mechanism held a press conference on the afternoon of December 20th, inviting experts from immunization program, virology, respiratory and infectious diseases, children’s health and other fields to attend, introducing the medical services for key populations. Pay attention together!

—— About the treatment of illness—

　　Is it necessary for people to use COVID-19’s specific drugs, and can they take them by themselves?

　　Several antiviral drugs were recommended in the ninth edition of the diagnosis and treatment plan, including monoclonal antibodies, nematvir, and azvudine added later. The early use of these antiviral drugs may reduce the occurrence of severe diseases, shorten the course of disease and shorten the time of virus detoxification.At present, these three antiviral drugs are still emphasized to be used in medical institutions and under the guidance of doctors. In particular, monoclonal antibodies need to be administered intravenously and used during hospitalization, which is not suitable for use in outpatient clinics or at home.Naimatevir is a small molecule antiviral drug, which can effectively reduce the risk of severe illness, and the indications are mild and common.When using, we should pay special attention to the interaction between drugs. Some drugs, such as simvastatin and amiodarone, which are being used by the elderly with basic diseases, can’t use drugs such as nimatvir.Therefore, it is emphasized that this drug should also be used under the guidance of a doctor. Azvudine is also a small molecule antiviral drug, which is used to treat AIDS. It is found that it can shorten the course of disease, reduce the virus level and improve symptoms during the treatment in COVID-19, so it is also approved for marketing and can be used in COVID-19. Similarly,This drug also has some precautions, including that pregnant women can’t use it.,Use with caution if there is severe or moderate liver and kidney damage.Therefore, it is emphasized that it should be used under the guidance of a doctor.

　　What are the taboos in the use of common drugs after infection?

　　Generally, after being infected with Covid-19, people use more drugs called symptomatic drugs, that is, they have fever and general pain, and use some antipyretic and analgesic drugs. If you have sore throat, cough and expectoration, and gastrointestinal symptoms, use some corresponding symptomatic drugs. Some are prescribed by doctors, and some may be purchased by themselves.We must be optimistic about the instructions, dosage, frequency of use and other precautions.Some medicine,For example, acetaminophen is a commonly used antipyretic and analgesic, and its contraindication is that patients with severe liver and renal insufficiency should be banned.. For example, there are some people,People with recurrent digestive tract ulcers and bleeding, pregnant or lactating women or people who are allergic to certain antipyretic and analgesic drugs should also be cautious.. When you are advised to use these drugs again,Don’t drink alcohol or alcoholic beverages.. I hope that when you use these symptomatic drugs,Try to use simpler medicine.Because different drugs may sometimes interact with each other, which may increase the potential adverse side effects. There are also patients who have this tendency. In order to control the symptoms quickly, it is not recommended to double the dosage of the drug.Because doubling the dosage of the drug may not be effective, but it increases the burden on the liver and increases the side effects.Some Chinese patent medicines or soup medicines can also improve symptoms and have a certain rehabilitation effect. You can also choose them.

　　It is not recommended to cover the sweat to reduce the fever of the baby.

　　In fact, acetaminophen is the only antipyretic drug that children from 2 months to 6 months can choose. Children under 2 months cannot take antipyretics orally.Therefore, it has always been suggested that babies under 2 months, including newborns, must be sent to the hospital in time if they have a fever, so that medical staff can help the children.

　　It is not recommended to give a baby a fever by covering his sweat.The reason is that the development of baby’s thermoregulation center is not perfect, and skin heat dissipation is a very important way to reduce fever. If these children are covered with too many clothes or covers, they will have no way to dissipate heat through the skin. In the case of heat, their body temperature may be higher and higher, even reaching more than 40 degrees, which is not uncommon in clinic.And some children may have severe heat syndrome.Serious complications such as respiratory failure, dehydration, nervous system injury and even life-threatening may occur. Therefore, when these children have a fever, in addition to the help of medical staff,We should try our best to create a relatively cool and ventilated environment for children and reduce clothing appropriately to improve their comfort..

　　What should parents do if the child has febrile convulsion?

　　Febrile convulsion is a very common emergency in pediatric emergency. Respiratory infection caused by virus is the most common cause of febrile convulsion in our children.The age of children mainly involved is between 6 months and 5 years old, which usually occurs in the first 24 hours of fever, especially in the period of rapid temperature rise, and febrile convulsions are most likely to occur.Under normal circumstances, the child’s body temperature may reach above 38.5 degrees. Children with febrile convulsions usually show stiff limbs or shaking, clenched teeth, tilted eyes or upturned eyes, which may be accompanied by cyanosis of the lips. At this time, there may be no response to external stimuli. In the event of febrile convulsion, parents are advised to do the following.

　　First,Lay the child flat on a flat bed, table or floor.Don’t have sharp things around you, mainly to prevent the child from falling and secondary injury during the seizure.

　　Second,You can unbutton your child’s collar and keep his respiratory tract unobstructed..

　　Third, you can tilt your child’s head to one side. If possible,Keep the child lying on the right side,In case the child vomits, aspiration will lead to suffocation.

　　In the whole process, remind parents that there are several things not to do. First of all,Don’t put anything in your mouth when the child has a seizure., including spoon handles, chopsticks, fingers of adults, etc., because this may cause damage to children or adults themselves. Second, during the seizure,Don’t feed your child anything, including medicine and water.. Third, during the seizure,Don’t try to bind the child’s limbs.Don’t let his limbs twitch, because this may cause secondary injuries to his limbs. Fourth, so far,There is no evidence that pinching people can shorten the seizure time of children.On the contrary, parents may be particularly nervous and exert too much force during the seizure, thus causing soft tissue damage in this part of the child, so parents are not advised to pinch their children.

　　When the child has convulsions,To reduce unnecessary stimulation.. In general,The duration of children’s febrile convulsion is 3 to 5 minutes, and it can stop by itself. When the convulsion stops, the child can be sent to the hospital as soon as possible.However, if the child has had a state of convulsion in the past, or this episode has been more than 5 minutes, then in this process, the possibility of the child’s convulsion stopping on its own will be relatively small. Parents are advised to send the child to the hospital as soon as possible.

　　For the vast majority of children, febrile convulsions will not affect the development of the nervous system and will not leave behind sequelae of the nervous system, so parents need not worry too much.At present, there is no evidence that taking antipyretics in advance has a preventive effect on children with a history of febrile convulsions. At the same time, because the child’s body temperature rises very quickly, there is basically no way to prevent the occurrence of febrile convulsions.

　　Patients with chronic obstructive pulmonary disease should go to the hospital for further diagnosis and treatment after they are infected with COVID-19.

　　Chronic obstructive pulmonary disease (COPD) is a common chronic respiratory disease in China. The common symptoms of patients are cough and expectoration, sometimes accompanied by dyspnea, and often upper respiratory tract infection leads to the aggravation of the original symptoms. So when should I go to the hospital for further treatment? The first rule isContinue to have a fever, take conventional antipyretic and analgesic drugs, and the body temperature will not drop for more than two days.; The second isThe patient has listlessness, lethargy, listlessness and even unconsciousness, or some signs, such as cyanosis of the lips and edema of the lower limbs;The third isThe patient developed dyspnea, shortness of breath, wheezing,If the breathing frequency exceeds 30 beats/min, this is a sign of shortness of breath; Fourth, if there is a home percutaneous oxygen saturation monitor,Monitoring indicates that the patient’s oxygen saturation is ≤93%.It also suggests that there may be hypoxia; Fifth, after using some emergency drugs, such as bronchodilators, the symptoms of patients are not relieved or further aggravated; Sixth, patients with other symptoms, such as severe gastrointestinal symptoms, inability to eat, weakness, inability to walk, etc., all need to go to the hospital for further treatment.

　　How should patients with respiratory diseases be treated at home once they are infected with COVID-19?

　　If patients with chronic respiratory diseases have COVID-19, first of all, don’t panic, have a normal rest, drink plenty of water, eat balanced and digestible foods such as vegetables and fruits, and so on. Second, do some symptomatic treatment, such as fever, body aches, sore throat, cough, expectoration, etc., that is, take analgesics or drugs to treat sore throat, cough and phlegm. After all, patients with respiratory diseases are people with basic diseases, so they need to monitor their symptoms at home, especially cough, expectoration, shortness of breath and dyspnea. Third, some respiratory symptoms sometimes get worse during infection, even if it is common flu, common cold or virus infection. At this time, some symptomatic drugs should be used first.For example, if the symptoms of dyspnea and dyspnea get worse at once, first use some short-acting bronchodilators for emergency treatment. You can spray 1-2 inhalations at a time, and then inhale 1-2 inhalations every 20 minutes, with no more than 6-8 inhalations in the first hour.. If the symptoms gradually improve or stabilize through this symptomatic treatment, you can continue to observe the symptoms at home. If the symptoms change further, you can go to the doctor again. Fourth,Routine medication must be adhered to.. Fifth,To monitor oxygen saturation at home in time,Know whether the condition has changed in time.

About vaccination—

　　What do you think of the saying that "it is better for young people to be vaccinated than to be infected with Omicron"?

　　Although the pathogenicity of Omicron strain which is popular at present is weakened compared with other variants which were popular in the past. However, after being infected with Omicron mutant, there is still the risk of serious illness and death.This risk of serious illness and death will be reflected at all ages.It’s just that the risk of serious illness and death of the elderly, which we emphasized in the past, will be higher in the whole population. In addition, the proportion of people with basic diseases will be higher.

　　At present, many studies have shown that,Compared with those who have completed the whole course or strengthened immunization with Covid-19 vaccine, the risk of hospitalization or severe illness and death of those who have not been vaccinated is quite different, including young people and adults. If this risk exists to a certain extent, it can be reduced by vaccination. Therefore, it is suggested that those who have not been vaccinated should be vaccinated, and those who have not completed the enhanced vaccination should complete the enhanced vaccination as soon as possible.Whether it is the elderly, adults or young people, the risk is reduced to a relatively low level..

　　Can people who have recently recovered from infection be vaccinated with COVID-19 vaccine?

　　If Covid-19 has been confirmed recently,Covid-19 vaccination is not recommended in the near future.. At present, the immune protection produced by simple infection is not as strong as the mixed immune protection produced by infection and vaccination, so if vaccination is needed in the later stage, it is recommended to vaccinate. How long is this interval? According to the current technical guidelines for vaccination in Covid-19,If Covid-19 is diagnosed, the time between infection and Covid-19 vaccination should be more than 6 months.Of course, our immunization strategy will be continuously improved and adjusted with the understanding of diseases, vaccines and the need for disease control.

　　Can cancer patients be vaccinated with COVID-19 vaccine?

　　As for cancer patients, due to illness and chemotherapy, the immunity of some people will be low, which will increase the risk of serious illness and death. So, in this case,These patients need to be vaccinated with Covid-19 vaccine to be protected, and they are also among the priority groups for vaccination..

　　The clinical manifestations of cancer are actually varied, and the treatment process is also very complicated.Whether cancer patients who are in the onset or in the treatment stage can be vaccinated depends on the judgment of relevant professionals.. Because of the low immune function, the immune protection reaction of cancer patients after vaccination with COVID-19 vaccine may not be as strong as that of healthy people. In the "Work Plan for Strengthening Vaccination in Covid-19 for the Elderly", it is also specifically mentioned that "all localities should scientifically evaluate contraindications, and the specific reasons for those who do have contraindications should be clarified one by one", which is also applicable to the current evaluation of contraindications for cancer patients.

　　It’s been a long time since the whole immunization was completed. Is it still useful to carry out intensive immunization now?

　　After vaccination in Covid-19, there is a protective effect, one is to produce antibodies, the other is to produce cellular immunity and immune memory. After vaccination, the antibody level will decrease with the passage of time. In addition, with the variation of the virus, the immune escape is also enhanced, which further weakens the role of antibodies. But,Cellular immunity, especially in preventing severe illness and death, plays a lasting role..

　　Studies have shown that,Vaccination with booster needles can arouse the immune memory cells of the body on the one hand, and improve the antibody level on the other hand, further consolidating the preventive effect on severe illness and death.. Therefore, it is emphasized that those who have not completed the booster immunization should complete the booster immunization as soon as possible in accordance with the provisions of the immunization program as long as they meet the vaccination conditions.

About strain variation—

　　If a new mutant appears, there is still the risk of reinfection.

　　Now we are infected with BF.7 and BA.5.2,If a new mutant appears, there is still the risk of reinfection.. At present, from the data,The risk of reinfection or reinfection of Omicron strain is higher than that of the original strain, including higher than Delta and the original strain.. Judging from the time when the secondary infection appears, there is usually an interval, and it will not be said that it will be reinfected soon after infection.The probability of reinfection of the same strain is extremely low. Even if infected, there will be no obvious symptoms, which are generally mild.. Secondary infection mainly refers to the breakthrough infection of mutant, and the time interval of breakthrough infection is closely related to clinical manifestations. The shorter the interval, the lighter the symptoms, and the more severe the symptoms after the interval, which is directly related to the antibody immunity in the body. A study in Sweden also found that,After being infected with Omicron strain, the symptoms of secondary infection or tertiary infection with different strains in Omicron are very mild, and they are basically asymptomatic infected people or mild cases..

　　Of course, we should also pay attention to some elderly people. For example, we have done a study on American veterans. Among the elderly veterans, after the second infection, some patients do get worse or even die.Therefore, despite the infection, after the emergence of a new virus epidemic strain, personal protection should be done, especially for the elderly and those with basic diseases.In addition, it is very clear that vaccination in Covid-19 can effectively reduce the risk of severe illness and death. A study in Italy found that vaccination can reduce the incidence of secondary infection and reduce the probability of hospitalization after infection. So,The elderly and those with basic diseases should also emphasize vaccination..

　　What is the pathogenicity of BQ.1 and XBB strains, and will it trigger a new round of epidemic in China?

　　BQ.1 and XBB are new branches of variation in Omicron. Internationally, it has been gradually shown in some European and American countries that they are dominant strains.The main manifestation is the increase of transmission ability and immune escape ability, but its pathogenicity is not obviously different from other series of variants in Omicron.The severe illness rate and mortality rate have not increased significantly in these countries where BQ.1 and XBB are prevalent.In recent three months, BF.7, BQ.1 and XBB have been detected in China.A total of more than 130 subfamilies from Omicron were imported into China, and these 50 subfamilies caused related local cases or outbreaks.The whole BQ.1 and XBB have not yet formed a dominant communication in China (at present, BA.5.2 and BF.7 are still the main ones).However, its propagation advantages will gradually increase, and it may form a common cycle with BA.5.2 and BF.7, as well as other sub-branches with more than 50 inputs.

　　The prevention of BQ.1 and XBB is actually the same as other Omicron mutants, that is, to monitor whether its pathogenicity has changed or not, and whether its genome has further variation. If its clinical characteristics have changed, we will link it with the genome characteristics for judgment.However, there is no report that BQ.1 and XBB cause serious illness and death at home and abroad..

　　It is less likely that a highly contagious and highly pathogenic strain will appear.

　　From the appearance of Omicron in November 2021 to December 18, 2022,There are 709 sub-branches in the world, which have evolved from the five branches of BA.1 to BA.5., including recombinant strains, there are 72 strains produced by recombination between these subfamilies, and XBB is one of these 72 strains. Therefore, the variation of Omicron will continue. As long as it circulates in the crowd, it will replicate, and replication will mutate. The genetic variation of the virus itself may lead to the change of some antigenic epitopes and increase its immune escape ability. So the variation trend in Omicron is,Those with strong immune escape ability are dominant.. Immune escape makes people susceptible to this strain, even if its spreading power is not enhanced, its spreading advantage will still increase.

　　Will it increase its spreading power and lethality? This possibility is relatively small.The cases of hospitalization, death and severe illness caused by Omicron were significantly lower than those caused by early Delta strain and other VOC variants. Therefore, no significant increase in severity and death was observed throughout more than 700 branches.Therefore, on the whole, it is less likely that the pathogenicity will increase significantly. It is even less likely that it will have a more infectious and lethal strain. Nowadays, people have obtained a certain degree of immunity through vaccines or natural infections, which has good protection for people. Even if the virus mutates again, the risk of transmission will increase unless some subversive recombination leads to complete immune escape, but this possibility is relatively small.Therefore, on the whole, it is unlikely that there will be strains with high infectivity and high pathogenicity.

　　What are the monitoring methods for epidemic mutant strains in China at present?

　　After the optimization of the national COVID-19 epidemic prevention and control strategy, China CDC Institute of Virology formulated the Work Plan for Monitoring Covid-19 Mutant in Chinese Population according to the co-circulation of several Covid-19 subtypes in China. Scheme requirementsChoose three cities in each province and one sentinel hospital in each city. Each sentinel hospital takes samples of 15 emergency cases, 10 severe cases and all deaths every week for genome sequencing and analysis, and uploads the sequencing data to CDC Virology Institute in China within one week, and we establish the national Covid-19 genome database.. Through the implementation of this scheme, the epidemic dynamics of Covid-19 Omicron series mutants in China and the composition ratio of each subtype can be dynamically monitored in real time, and new mutants with potential biological characteristics change, including clinical manifestations, transmission power, pathogenicity and so on. It provides scientific basis for vaccine development and diagnostic reagent evaluation (including nucleic acid and antigen, etc.).

-other-

　　How to treat the saying that "Erwin Engst is good early"?

　　Although Omicron is highly contagious, most of it is self-limited after infection, and its pathogenicity or severity is relatively low, butIntentional infection is not advocated or recommended.. Also emphasize that,The elderly, those with basic diseases, especially those who have not been vaccinated, must be well protected from infection in the first round of epidemic peak.. At this epidemic peak, there may be problems of uneven distribution of medical resources or a run, which will lead to the failure of timely and effective treatment for critically ill patients. We still hope that these elderly people will be well protected, including those in nursing homes and those who are bedridden with basic diseases. Everyone should pay special attention to avoid infection. At the same time, those who have not been vaccinated will continue to be vaccinated.

　　At the stage of the first round of rapid epidemic growth, with the passage of time, the number of infected people will increase, and the rapid upward trend will slow down, which is a universal law. But,After a period of time, with the extensive development of large-scale social activities, including Spring Festival travel rush or various social activities, there may be a new round of epidemic. The wave appearance of this epidemic may eventually form a certain group immune barrier, and the incidence rate will drop significantly..

　　What are the criteria for judging COVID-19’s death at present?

　　Different from the epidemic situation in Wuhan in early 2020, most patients died of respiratory failure in COVID-19 at that time. Now, after Omicron virus infection, the proportion of pneumonia in upper respiratory tract and lower respiratory tract is relatively low, and some patients have pneumonia, but the cases leading to respiratory failure are rare. As seen from clinical practice,At present, the main cause of death after Omicron virus infection is basic disease, and respiratory failure caused by Covid-19 infection is rare..

　　In order to reflect the deaths caused by the COVID-19 epidemic scientifically, objectively and realistically, National Health Commission recently organized experts to demonstrate and issued a notice, clearly classifying the related deaths scientifically. Mainly in two aspects,Pneumonia and respiratory failure caused by Covid-19 are the primary diagnosis of death, which is classified as death caused by Covid-19 infection.; Death caused by other diseases and basic diseases, such as cardiovascular and cerebrovascular diseases and myocardial infarction, is not classified as death caused by COVID-19. In order to better standardize the judgment of death caused by COVID-19 epidemic, it is required to adopt the way of consultation and death case discussion to finally judge whether the patient died of COVID-19 or other basic diseases.

　　In the view of Chinese People’s Political Consultative Conference Commissioner Wang Meihua, it is difficult for teenagers to resist the temptation of online games, because the highlight of online game design is that people are addicted to it, and attraction is its goal.

　　Future Network, Beijing, March 12 (Reporter He Zhuohui, Liao Jin) On the one hand, the overall revenue of online games reached 218.96 billion yuan, which is equivalent to the good news of the global box office, and on the other hand, the tragedy of the sudden death of a 12-year-old boy addicted to online games. Behind the rapid development and prosperity of online games, is it at the expense of the physical and mental health of teenagers? During the two sessions of the National People’s Congress, teenagers became addicted to online games, which triggered a heated discussion among NPC deputies and CPPCC members. Some members even angrily denounced: "Online games should be killed with a stick!"

　　"Online games are psychotropic drugs." Hu Wanning, member of Chinese People’s Political Consultative Conference and president of Tangshan People’s Hospital, said that online games should be controlled like drugs.

　　Hu Wanning was "deeply touched" by the problem of online games because he saw some children addicted to online games and almost didn’t graduate from college.

　　He believes that teenagers don’t benefit much from the game itself, and it is very likely that they will spend the best time of their youth in the game and be depressed. Hu Wanning is worried that online games are highly addictive. "If left unchecked, our younger generation will be really unimaginable.". The harm is not limited to young individuals. Hu Wanning also pointed out that "even some online games may be infiltrated into China by some countries with anti-China purposes."

　　In the view of Chinese People’s Political Consultative Conference Commissioner Wang Meihua, it is difficult for teenagers to resist the temptation of online games, because the highlight of online game design is that people are addicted to it, and attraction is its goal.

　　However, Ma Huateng, deputy to the National People’s Congress and CEO of Tencent, has different views. He pointed out that online games should not be demonized blindly, but the positive value of games can be further exerted. With the recent popularity of ‘ Jump ’ For example, he said that many elderly people reported that they felt good and prevented brain dementia, and thought the game was "quite fun and simple".

　　Also engaged in network technology, Ding Lei, member of Chinese People’s Political Consultative Conference and chairman and CEO of Netease Company, further analyzed and pointed out that children playing online games are lonely, and they lack better TV dramas and audio books suitable for children. At the same time, there is also a lack of other social activities. He does not exclude teenagers from playing online games, but also said that he would personally choose online games for his daughter to try out.

　　Not long ago, Netease announced its unaudited financial results for the fourth quarter ended December 31, 2017. The data shows that Netease’s net income in 2017 was 54.102 billion yuan, of which the net income from online game services was 36.282 billion yuan, an increase of 29.7% compared with 2016.

　　Both Netease and Tencent are profit-makers in the game industry, emphasizing the positive side of online games. Wang Jianguo, a member of Chinese People’s Political Consultative Conference and director of CCTV’s recording channel, thinks that their statements are hypocritical. "They emphasize the positive side of [online games]. For merchants, it is a bit hypocritical for you to emphasize only the positive side. " Wang Jianguo said.

　　In life, Wang Jianguo saw a living example of the harm of online games. "I have a friend, the couple are schoolmasters, one is from Tsinghua and the other is from Peking University, but their children can’t get into key middle schools, and their academic performance has been poor." Wang Jianguo explained the reason: children are addicted to one of the most popular mobile online games.

　　Although Ma Huateng mentioned in the interview that the Youth Growth Guarding Platform launched by tencent games has been running for one year, many parents are using it now, and the effect is obvious. In addition, in last year’s hit game "the glory of the king", Tencent also launched a health system, which allowed children under 12 to play only one hour a day and not play games after 9 pm.

　　Li Yanhong, a member of Chinese People’s Political Consultative Conference and founder of Baidu, also said that it is necessary to control the length of online games played by teenagers through software programs. However, Wang Jianguo believes that besides strict restrictions on the time of games, the content of online games, including the excitement of making teenagers addicted and fascinated, should also be studied one by one.

　　Li Yanhong said that at the same time, legislation should be followed up, and more legislative actions are needed in relevant legal provisions, especially in protecting the physical and mental health of young people. For online games, special expert committees are needed to define the advantages and disadvantages.

　　One side shouted strict control, and the other side cleared the name for online games. Whether online games are evil or not, should they be killed with a stick? Which is better, blocking or dredging?

　　"It is better to guide properly by blocking." Hu Wei, member of Chinese People’s Political Consultative Conference and deputy chairman of the Shanghai Municipal Committee of the Democratic Progressive Party, believes that online games are not necessarily bad for all children. Parents have the greatest responsibility to keep their children from indulging and being led by the nose by online games.

　　Parents need to attach importance to family education, give their children a lot of companionship, have more communication with their children, know what their children lack and need to make up, and guide their children appropriately through communication and interaction, so that they can distinguish when to play, when not to play, when to study and when to do homework.

　　Ou Yanling, member of Chinese People’s Political Consultative Conference and deputy director of the Standing Committee of the People’s Congress of Luocheng Mulao Autonomous County, also thinks that it is not appropriate to "kill the game with a stick". Because with the improvement of people’s living standards, there is more demand for culture or entertainment.

　　"We can’t deny that games let you spend your leisure time, or get some satisfaction in other aspects, but game producers should also enhance their sense of social responsibility and improve their awareness of cultural communication and moral communication. Produce more games that are beneficial to everyone’s physical and mental health in a very responsible attitude. " She pointed out that some online games are full of violence and negative energy information that teenagers should not be exposed to, and some national heroes and traditional celebrities in China are used as a kind of joke to fill the games, which should be eliminated from online games and prohibited.
