Every reporter Ma Weimin sent it from Beijing.

After WeChat blocked the Alipay red envelope sharing link on February 3, and the micro-store merchants could not use the Alipay portal on the WeChat public platform, the information embargo between Ali and Tencent was upgraded again.

Yesterday (February 4th), many users found that they couldn’t share the link to WeChat from Netease Cloud Music App, and Xiami Music and Tiantian were also blocked. National business daily reporter noted that both Xiami Music and Tiantianyingying are "Ali": Xiami Music was merged into Ali Music Division in 2012, and Tiantianyingying was acquired by Ali in 2013. Therefore, the ban was pointed to Ali.

At present, Xiami Music and Tiantian Yingmei have not responded. However, Netease Cloud Music, which is "lying on the gun", seems to express "understanding": "Sorry to the users of Netease Cloud Music. Because WeChat is theirs, they need to make a choice for themselves, and said, "Don’t blame WeChat, this is what they should do."

Music becomes the object of support/

Yesterday, many users found that the link to wechat could not be shared from Netease Cloud Music App. The page prompt message was "Because the currently shared application is suspected of containing content that infringes on the legitimate rights and interests of others, it cannot be shared with WeChat." A user told the national business daily reporter, "I was fine yesterday, but I suddenly can’t share it today. I feel very surprised."

The reporter downloaded several other music apps. After operation, it was found that at present, except Netease Cloud Music, Everyday Listening and Xiami Music, other music apps, such as Baidu Music, Cool Dog Music and Cool Me Music, can be shared to WeChat friends circle normally. Obviously, this shielding is not a technical failure.

According to public information, Tiantianyingmei and Xiami Music are "Ali-related" companies. In fact, as the two major Internet giants in China, the investment and layout of Tencent and Ali involve almost every field, and music has become a new position in this ban war.

An Internet analyst who asked not to be named said that Tencent’s strategy is to rely on each product to fight for the survival of the fittest in the early stage, and in the later stage, especially in key areas, it is necessary to rely on WeChat.

Liu Chiping, president of Tencent, previously said in a public speech, "Comparing the top 20 DAU (daily active users) apps in China, 3.5 of the top 5 are Tencent’s and 7.5 of the top 10 are Tencent’s, but there are still many applications, such as video, e-commerce and music. Can we accelerate the mobilization of products in the future? This is what we hope to do vigorously in the second half of the year."

He said that Tencent is now comprehensively strengthening copyright and content construction in the fields of games, animation, games, videos and music. In 2014, WeChat has tried to combine with game e-commerce, and it is only a matter of time before digital music is opened in the future.

For a long time, Tencent has not made much achievements in the field of digital music. Compared with Ali’s investment layout, the pace is slightly smaller. However, from the perspective of the whole music market, digital music is actually very promising. Although pirated music has been rampant in previous years, with the more standardized system, users’ habit of using genuine music has been constantly improved, and music is a daily necessity for ordinary users. In any case, this is also a market that will not be easily given up.

"Music is a huge market just needed, and it has the potential of entertainment traffic entrance. It is a very good supplement and extension for WeChat. After WeChat killed Xiami Music, Tiantianying and Netease Cloud Music, it is estimated that QQ music has made great moves recently." The above analysts said.

An industry insider commented, "After WeChat killed Xiami Music, Everyday Music and Netease Cloud Music, the music sharing in the circle of friends was reduced by a large part, and QQ music was basically growing in the greenhouse.

Before this ban on music apps, WeChat just blocked the Alipay link. An industry insider who asked not to be named told the national business daily that with the Spring Festival approaching, the red envelope war between Ali and Tencent is on the verge, and both sides have made every effort to try it this year. Although the red envelope was first developed by Alipay, WeChat has stronger social attributes than Alipay, and products like red envelopes are easier to circulate in the chain of friends and groups. Last year’s Spring Festival red envelope detonated the whole country, which is an example, so WeChat is very afraid of competitors coming in for a share, even if it is.

In fact, after the shielding upgrade between Ali and Tencent, the two sides are also thinking about recruiting children. On the night when the Alipay red envelope was blocked by WeChat, Alipay launched the "password red envelope" function. If the user clicks Share to WeChat friends circle when sending a red envelope, a string of 6-digit passwords will automatically appear, and there is a button to save the picture and share it to friends circle at the bottom of the page. After the screenshot of the user is sent to friends circle, WeChat friends can participate in the activity of grabbing the red envelope as long as they enter the password in Alipay.

In other words, after the link interface was blocked by WeChat, Alipay chose to continue to share the red envelope in the circle of friends in the form of pictures with information, and due to the difficulty and accuracy of identifying the contents of the pictures, WeChat could not continue to block and block the pictures with Alipay password red envelopes.

An official Alipay spokesperson told the national business daily that the function was developed because Alipay took a fancy to the huge user group and activity of WeChat. She doesn’t agree that it is too much trouble to grab a red envelope under this function. "You just write down the password and then open Alipay to input it. The process is not much slower than clicking on the link to jump."

Regarding the data of the red envelope amount currently shared by Alipay on WeChat, she said that it is not convenient to disclose it at present. "The data will not be released before the Spring Festival, and an overall data will be released after the year."

In an interview, Luo Yihang, the founder of Pingwest Pinwan, described the blocking between BAT as "the new Berlin Wall". He said, "After the continuous merger and integration in 2012-2013, Internet companies in China presented an unprecedented pattern of two poles and at most three poles. This pattern is precisely the outbreak period of mobile Internet tools since the 3Q War in 2010, and large and small companies are working hard together ‘ Open platform ’ And ‘ Open API’ The result. Now, major companies are basically in a clear camp. If there is a slight wind and grass or the environment is not conducive to them, they will immediately cut off the API (data interface) and start to block the shielding. "

Many problems with the ankle are related to wearing shoes. What should we pay attention to when choosing shoes？

　　Health is an inevitable requirement to promote people’s all-round development, and it is also the common pursuit of the broad masses of the people. At present, with the continuous improvement of people’s health awareness, more and more people realize the importance of sports and actively participate in various sports. However, in the process of exercise, many people have done some damage to their bodies due to lack of knowledge and blind pursuit of exercise. This edition invites experts to explain the injuries that are easily overlooked in life.

　　As the saying goes, "A journey of a thousand miles begins with a single step", and ankle health is the foundation of human standing and sports. However, about a quarter of the people in the world are suffering from ankle diseases to varying degrees. However, due to the hidden symptoms of foot diseases, it is easy to be ignored and delay treatment, thus affecting the quality of life.

　　1. Most ankle diseases are acquired.

　　Bipedal is called the second heart of human body, which is very important to human body.

　　Although the ankle is only a small part of our whole body in terms of volume, and the area of joint contact is much smaller than that of knee joint or hip joint, the ankle bears the weight of our whole body, which will inevitably lead to higher local pressure of joints than other joints, and it is more prone to injury.

　　Foot and ankle is an extremely complex structure, including foot and ankle, and foot is divided into three parts: forefoot, middle foot and hind foot. A small ankle part, the bones alone involve tibia, fibula, and tarsal bones 7, metatarsal bones 5 and toe bones 14, a total of 28. It’s more complicated in terms of joints. Besides the ankle joints (tibiofibular joint, tibiofibular joint and talofibular joint) that we all know, there are tarsal joints such as talocalcaneal joint, talocalcaneal joint, calcaneal roll, cuneiform joint, cuneiform roll and cuneiform roll, tarsometatarsal joint, metatarsal joint, metatarsophalangeal joint and interphalangeal joint. From the research field, it includes ankle trauma, podiatry and orthopedics. It should be emphasized that apart from congenital factors, such as congenital clubfoot and flatfoot, most ankle diseases are acquired, such as ankle ligament injury and heel pain.

　　Due to the extremely complex structure of the ankle, many kinds of diseases in each part, and the strength of our whole body in daily life, these factors make our ankle more prone to problems, and the ankle problem is more difficult to treat. Excessive exercise and trauma can cause various ankle diseases, especially ankle sprain, which accounts for 40% of sports injuries. It can be seen that ankle disease is a big problem, and what is most closely related to people, but most easily overlooked, is how to wear shoes.

　　2. Many problems with ankles are related to wearing shoes.

　　Speaking of it, people have been wearing shoes since they learned to walk. Can’t they choose shoes? In fact, most people may not know that many problems with ankles are related to wearing shoes.

　　Bad shoes not only easily cause ligament damage, but also easily lead to many diseases in the ankle. A typical example is that many women who love beauty often wear high heels to cause foot pain. Different heel heights will lead to different forces on the forefoot when walking. The higher the heel, the greater the pressure on the forefoot and the worse the stability when walking, which will cause forefoot pain. At the same time, most of the high-heeled shoes are pointed leather shoes, and when they are worn, they squeeze into the big toe, which is easy to cause the big toe to valgus, which in turn causes the lateral arch of the forefoot of the second to fifth toes to sink, further causing forefoot pain. Overloading the forefoot for a long time will also cause some foot diseases or appearance changes, such as metatarsalgia and Morton’s disease, which are related to wearing high heels for a long time. In addition, the heel of high-heeled shoes is generally thin, which will reduce the stability of the back of the ankle when worn, so it is easy to cause ankle sprain. Therefore, in life, if female friends like to wear high heels very much, it is suggested to choose a high-heeled shoe with low heels and a slightly wider forefoot design. It would be better if we can strengthen the muscle strength of the calf, which will help to increase the stability of walking in high heels.

　　3. What should I pay attention to when choosing shoes?

　　● You can’t have only one pair of sports shoes. What kind of sports shoes should you wear?

　　Although we all know that we should wear sports shoes when exercising. However, it needs to be reminded that no sports shoes can be suitable for all sports. For example, basketball shoes for playing basketball require a thicker sole, a flatter overall, and a higher upper at the back to prevent sprains and slips. Football shoes running on the grass require more flexible ankle movements and lower uppers. The ground where tennis is played is usually hard, which requires shoes to have anti-slip cushioning effect. Jogging, on the other hand, requires slightly lighter jogging shoes with shock-absorbing air cushions. People who exercise regularly must prepare shoes for the corresponding sports.

　　● It is necessary to cut the shoes properly, not to cut the shoes properly.

　　Everyone looks different, and the 28 bones of the ankle are naturally different. It can be said that billions of us can’t find the same feet. To a large extent, the arch of the foot is high and low, and the feet are wide, narrow and fat, all of which need special attention when choosing shoes. For example, people with flat feet have poor cushioning when walking with load, and their feet will hurt when walking too much, so try to choose shoes with raised arch pads. Some people have wide toes, or have eversion, so they should choose loose toes, otherwise it will cause wear between toes, and long-term walking will cause pain. In addition, people with heavy weight should choose elastic shoes when choosing shoes to reduce the impact of walking on the soles of their feet.

　　● Older people choose shoes not as soft as possible.

　　With the increase of age, the fascia and ligament of the ankle will also age, and the bones and joints will also undergo degenerative changes. Compared with young people, the ankles of the elderly are more vulnerable to injury, and the speed of recovery after injury will be much slower than that of young people. Therefore, the elderly should pay more attention to the choice of shoes. A common misconception is that the elderly like to wear soft-soled cloth shoes, and feel that the softer the better. In fact, too soft soles can’t give enough support to the soles of the feet, and at the same time, too soft shoes can’t provide good elastic cushioning, which will increase the damage to the soles of the feet. Old people should choose shoes with sufficient cushioning and good elasticity. The part of the insole that directly contacts the foot surface is also required to be relatively soft and fully fit to the sole of the foot. In addition, if the blood circulation of the soles of the feet of the elderly is poor, they should choose looser shoes. The requirement is not only that there is no squeezing and grinding of the feet when trying on, but also that there is no grinding of the feet when the feet are slightly swollen.

　　● Good-looking and expensive shoes are not necessarily suitable shoes.

　　In modern society, shoes are not only a tool to protect the body from cold, but also an aesthetic requirement and even a symbol of identity. Some shoes are worth several thousand yuan or even ten thousand yuan. However, it needs to be reminded that no matter how beautiful shoes are, you can’t have them if they are not suitable for your feet. Just as many women will find that wearing high heels can cause foot pain, sometimes, expensive shoes are not necessarily suitable shoes. For example, for patients with lateral ankle ligament injury, it is recommended to wear some high-top shoes. This is because a higher upper can provide stability to the ankle joint and reduce the occurrence of sprained ankle. For patients with hallux valgus, when choosing shoes, we should try to reduce the pressure on the forefoot and try to avoid wearing high heels. Similarly, women who often sprain their ankles should wear less high heels, especially those with extremely high heels. Because when wearing high heels, our ankles are in a "plantar flexion" position, which is relatively loose, and thin high heels are not easy to stabilize, which will increase the chance of spraining our ankles.

　　● Don’t wait for the soles to wear out before changing shoes.

　　Although we advocate hard work and simplicity, from the point of view of protecting ankles, don’t wait for the soles to wear out before changing shoes. From the above, I believe everyone already knows that everyone’s feet are different. A pair of suitable shoes needs to have a high fit with your feet. When the sole of a pair of shoes is worn thin, the shape of the shoes changes accordingly. At this time, these shoes are no longer suitable for you and need to be replaced. In life, we often find that a pair of shoes are always worn in a certain part. For example, sometimes, the inside of the heel is worn thin, and other places are fine. In this case, many people are reluctant to change their shoes. But in fact, in layman’s terms, it is this worn-out sole that replaces our feet to bear the damage caused by walking. If it is not replaced in time, it will be our feet that will be damaged next.

　　● Foot pain must not be tolerated, and timely medical treatment is the key.

　　Ankle is a complex structure, and everything can’t be done just by choosing the right shoes. Once there is pain in the foot, you should see an ankle specialist in time. What needs to be understood is that many diseases of the ankle need surgical treatment, and there are still many diseases of the ankle that need standardized rehabilitation training, so I hope everyone will not be careless, so as not to delay the treatment and bring serious consequences.

Japanese media sneak shots of China overseas base netizens angered that ＂8 meters thick walls can’t stop you.＂

　　CCTV News:Recently, the Japanese side has made frequent "small moves" against China, and it seems that a series of ridiculous things have happened, which can’t be described by the word "drama essence".

　　On December 5th, the Japanese Inter-Party Parliamentarians’ Union "Let’s Visit the Yasukuni Shrine Parliamentarians’ Meeting" collectively visited the Yasukuni Shrine in Jiuduanbei, Tokyo. The domestic media called this behavior "collective worship of ghosts"!

　　What is even more striking is that Ishigaki City, Okinawa Prefecture, Japan also intends to change the name of the Diaoyu Islands to "Ishigaki City Dengye City Senkaku", which has been proposed at the regular meeting of the City Council. The Japanese Foreign Ministry responded strongly: "China urges China to face up to history and reality, stop making troubles on this issue and avoid damaging the momentum of improving relations between the two countries."

　　Many netizens in China expressed their helplessness to these "small tricks" in Japan, and commented one after another: "It’s really like a child to fool around again"; Turning black and white upside down, it seems that the Japanese right wing is going to be the enemy of the world.

　　Stealing the Djibouti security base, saying that the wall is 8 meters thick. Netizen: "That didn’t stop you."

　　Apart from these "willful" actions, the most speechless thing is that the Japanese media really "care" about China’s military development.

　　On December 3rd, Japan’s NHK TV station focused on China’s logistics support base in Djibouti, and paid attention to it for two consecutive days with the topic of "rare and precious shots". (Video screenshot)

　　As can be seen from the report video of NHK, most of the shots were taken a few kilometers away from our support base in Djibouti. Because it was too far away, we had to use a high-powered camera lens for this purpose. But surprisingly, their reporter didn’t get off the bus for an interview, but hid in a moving car to report, even without rolling down the window.

　　The news screen is wobbly, and I feel a little dizzy after watching it for a long time, and the pixels are also very spicy. What kind of interview "style" this is is very puzzling. Some people will say, can’t you take a closer look? Answer: Of course not! Because this is not their own backyard, but the military station of other countries. To put it simply, this is a "sneak shot"! ! !

　　When it comes to sneak shots, our first reaction is generally paparazzi and wretched man … … It is really difficult to associate this word with a national media. However, this is a general situation. Civilized manners limit our imagination. In two cases, Japan has broken through our cognitive level of state-to-state relations … …

　　NHK made a detailed report on China’s base in Djibouti by combining bold sneak shots with "reasonable imagination". They said that the base is surrounded by a high wall with a thickness of 8 meters, and the solid design reminds people of the famous Great Wall of Wan Li; You can see soldiers on duty at the sentry post.

　　In this regard, China netizens are very helpless: "8 meters thick can’t stop you!"

　　Others are worried about the common sense of the Japanese media: "This math is taught by a physical education teacher. How high is it if it is 8 meters thick?"

　　Some netizens said, "What if the Great Wall of Wan Li is built? Did you use your bricks to build the wall? Still connected to your home wifi. "

　　In fact, the Japanese have always been suspicious of China’s overseas military forces and have ulterior motives. Not only did they spy on our security base, but in August this year, they even interfered with China’s escort ships docked in Djibouti. In fact, however, China’s construction of overseas support bases in Djibouti is only to better ensure China’s troops to carry out international peacekeeping, escort in the Gulf of Aden and Somali waters, humanitarian relief and other tasks. This will play a positive role in effectively fulfilling China’s international obligations and maintaining international and regional peace and stability.

　　A spokesman for the Ministry of National Defense responded that "we don’t care" because we were angered by our residents for taking candid photos.

　　Looking far away, Japanese spying on China has a long history.

　　Long before the Sino-Japanese War of 1894-1895, the Japanese government had woven a tight spy network to provide accurate information basis for decision makers to formulate specific principles, policies and tactics of aggression against China. After the "September 18th" incident, the Japanese army launched a full-scale war of aggression against China, and Japanese spies even wreaked havoc in China.　　

　　However, the shadow of defeat has not prompted this country to reflect. Today, nearly 100 years later, facing the rising and powerful China, their mentality is more complicated.

　　At the end of 2016, Liaoning, the first aircraft carrier of China Navy, conducted its first offshore drill. After leaving the western Pacific Ocean, it sailed to the South China Sea along the eastern waters of Taiwan Province. The Japanese side was not idle, and quickly released its so-called "Liaoning carrier formation trend" and took related pictures.

　　On December 29, 2016, in response to the question of Japanese warships tracking and monitoring the Liaoning ship, Yang Yujun, then spokesperson of the Ministry of National Defense, said: "Everyone has a love for beauty. The Liaoning ship is both mighty and beautiful, and some people are interested in it, whether it is from a distance or voyeurism, as long as it does not violate relevant laws and does not hinder the safety and freedom of navigation, we don’t care."

　　Spending manpower, material resources and attention to "sneak shots", but getting a sentence "We don’t care", ask how big the psychological shadow area of Japan is … …

　　The Japanese side paid too much attention to China’s "nonsense" sneak shots, which even aroused the resentment of its own residents.

　　In October 2016, the Japanese current affairs magazine SAPIO published an article saying that "China Navy is secretly building an aircraft carrier on Changxing Island in the lower reaches of the Yangtze River". The report also described the reporter’s detailed experience of sneaking into the vicinity of the base, and even photographed a shadow similar to the hull, "but it is impossible to judge whether it is part of the aircraft carrier."

　　But in fact, China officials are not secretive about domestic aircraft carriers as described by Japanese media. As long as they search online with their fingers, they can find photos of the latest development of domestic aircraft carriers through formal channels.

　　Japanese netizens also spit out the reporter, "If it’s confidential, why don’t you get arrested" and "It’s funny to take what you heard in a taxi as news" … …

　　In less than three years, 12 Japanese spy experts were arrested and said that "sneak shots" entered a period of high fever.

　　As experts said when the Sino-Russian military exercise was over-interpreted by the Japanese media in 2014, if the mentality is unhealthy, "thieves look at everyone like police." In recent years, the pace of China’s enriching the country and strengthening the army has been accelerating, and Japanese peeping and sneak shots of our country have also entered a period of high fever.

　　According to Japanese media reports, from May 2015 to September 2017 alone, 12 Japanese were detained on suspicion of spying in China.

　　Wang Guangtao, an associate researcher at the Center for Japanese Studies at Fudan University, said in an interview with the media that "all people are spies", "recruiting spies with heavy money" and "focusing on the navy and military ports" are several important features of Japan’s espionage activities against China. Apart from maritime activities, science and technology and the development of first-tier cities are also the focus of their attention. Because of this, Japanese netizens in China jokingly called him "China’s royal photographer". Whenever there is a "sneak shot" of China news, netizens always reply in time that "the royal photographer has made a new move".

　　However, jokes are jokes. After the adoption of the Anti-Spy Law in 2014, China has not been soft in cracking down on spies. Experts suggest that both the government, the media and the people have an obligation to further guard against Japanese espionage.

　　If you encounter anything unusual, you must remember to go up and ask, "Hey, buddy, what are you shooting?" (Text/Fan Fan)

　　What’s the weather like when the large-scale summer harvest begins?

　　According to previous reports, this year, the harvest period of winter wheat in Jianghan, most of Jianghuai and western Huanghuai is concentrated in late May, and winter wheat in southern North China and eastern Huanghuai will mature in early June.

　　According to the monitoring of the Central Meteorological Observatory, since mid-May, the rainfall process in winter wheat and rape producing areas such as southern North China, Huanghuai and the middle and lower reaches of the Yangtze River has been frequent, and the accumulated precipitation has generally exceeded 50 mm, with 100 ~ 300 mm in southern Henan, western and southeastern Hubei, most of Anhui and central and southern Jiangsu, which is 80% to 2 times more than normal. During the period, strong convective weather such as 7 ~ 9 thunderstorms and local hail occurred in central and southern Hebei, Shandong, Henan, Anhui and Jiangsu.

　　Heavy rainfall and strong convective weather have adversely affected the filling maturity of rape and winter wheat in some areas, waterlogging occurred in low-lying farmland, and local winter wheat lodging occurred. The summer harvest in Hubei, southern Anhui and southern Jiangsu was temporarily blocked.

　　In the next ten days, winter wheat in Jiangsu, Anhui, Henan, Shandong, Hubei and other places will enter the stage of concentrated harvest, and a large area of summer harvest will start. What is the weather situation in these areas?

　　According to the forecast of the Central Meteorological Observatory, it will be sunny and sunny in the above areas from May 29th to June 7th, and the meteorological conditions are generally favorable for harvesting summer crops. Meteorologists suggest that the above-mentioned localities seize the favorable opportunity to harvest mature wheat in time, and the harvested areas should pay attention to drying and ventilation storage to prevent germination and mildew.

How to eat a healthy breakfast for children？ Experts say it should contain at least three kinds of food.

　　Zhang Wenhong, director of the Infectious Diseases Department of Huashan Hospital affiliated to Fudan University, recently said that "porridge is not allowed in the morning" caused a heated discussion. Zhang Wenhong’s main points are: pay attention to the diet structure, suggest taking high nutrition, high protein and adequate vitamins, avoid junk food, choose digestible food according to the condition, and eat fish residue (meat) when drinking fish soup.

　　Then, from the perspective of nutrition, is the dietary advice given by Zhang Wenhong scientific and reasonable? What should a healthy breakfast for school children look like? Let’s pick out a few issues that everyone cares about to discuss.

　　Can porridge and pickles be eaten after all?

　　What is porridge? Porridge is a thick paste-like staple food form made by boiling rice, millet, corn and other grains. Judging from its nutrient composition, nearly 90% is water, nearly 10% is gelatinized starch, that is, carbohydrates, in addition to a small amount of protein, dietary fiber and vitamins.

　　The nutritional advantage of porridge is that it is easy to digest and absorb, and it is suitable for people with poor digestive function, such as gastrointestinal discomfort, diarrhea, cold and fever, or people in recovery after surgery. These people are often accompanied by loss of appetite, and sometimes they need to be accompanied by pickles to stimulate their appetite. But porridge also has shortcomings, that is, the density of energy and nutrients is low. 90% of the porridge is water, so drinking porridge is basically enough. With pickles that can be eaten, at most, it is enough sodium, but protein, fat, vitamins and minerals are far from enough.

　　Therefore, whether porridge and pickles can be eaten depends on the specific situation. If children have normal digestive function and good appetite, but let them drink porridge instead of solid staple food for a long time, it may lead to insufficient intake of energy and protein. This unbalanced nutritional state will reduce the body’s resistance to diseases, which is the main reason why Zhang Wenhong emphasized that "porridge is not allowed in the morning". If the child is sick, whether it is a cold, fever, diarrhea or in the recovery period after surgery, he often can’t eat his daily meals. Compared with not eating, drinking some porridge can also supplement some nutrition.

　　The reason why some people think that "drinking porridge is nutritious" may be that it confuses the situation of "disease recovery" and "disease prevention", and thinks that food that is conducive to disease recovery is also conducive to disease prevention. Accurately speaking, it is appropriate to drink porridge in the short term of illness recovery, and digestible food will promote rehabilitation; In the prevention of diseases, we should pay attention to the energy and nutrient density of food, and reasonably match the diet to obtain balanced and sufficient nutrition, so that children can maintain normal disease resistance.

　　Because the cooking process is similar, the nutritional characteristics of meat soup are similar to those of porridge, except that porridge mainly provides digestible and absorbed carbohydrates, while meat soup mainly provides digestible and absorbed nitrogen-containing nutrients, such as amino acids, short peptides and nucleotides. Zhang Wenhong emphasized that fish soup should be eaten, because protein is more insoluble in water than starch. Even if it is cooked for a long time, protein still mainly exists in solid meat. Therefore, parents should encourage their children to eat the meat in the soup while drinking the broth.

　　What’s good about milk and eggs for breakfast?

　　The nutrient density mentioned many times before is a concept used by nutrition to evaluate the nutritional value of food. Nutrient density = the content of a nutrient in food/the energy of the food is 1000kcal (kilocalories), that is, the degree to which the content of a nutrient in food can meet the supply of human nutrients compared with its energy.

　　For example, milk and cola, which are also liquid foods, contain almost the same energy per unit weight, but the protein density of milk is 56g/1000kcal, and the protein density of cola is 0g/1000kcal. Therefore, milk can be regarded as a highly nutritious food, while cola is a high-energy food with single nutrition and belongs to "junk food". Although there is no concept of junk food academically, we usually refer to foods with high energy, high fat, high sugar, high salt and other low nutrient density that are not conducive to long-term intake as junk food.

　　For school children, it is necessary to get proper energy and adequate nutrition through breakfast, such as protein, vitamins, minerals, essential fatty acids and dietary fiber. If you choose milk, eggs, meat, coarse and fine staple food, vegetables and fruits, it means you choose high-nutrient food. On the other hand, if you choose cakes, biscuits, instant noodles, milk drinks, pickles, sausages and other heavy-flavored or convenient foods with high processing degree, it not only means high calorie and low nutrition, but also may consume too many substances harmful to health such as nitrite and trans fatty acids.

　　Eating foods with low nutrient density for a long time will not only make children gain weight, but also lead to insufficient intake of nutrients such as protein, vitamins, minerals and dietary fiber. In the non-epidemic period, this may affect the normal development of children’s body and intelligence; During the epidemic period, considering the increased risk of infection and poor nutritional status of children who attend classes intensively, the body’s resistance to diseases may be reduced. Therefore, Zhang Wenhong repeatedly stressed that it is no problem for parents to arrange nutritious food for their children.

　　Protein is one of the essential nutrients for human daily metabolism and children’s growth and development. As Zhang Wenhong said, the important weapon antibody of the immune system is protein. He suggested eating milk and eggs for breakfast, mainly because these two kinds of protein foods have three advantages: first, they have outstanding nutritional value, both belong to high-quality protein, and their bioavailability is high; Second, the operation is simple, and a cup of fresh milk or yogurt and a boiled egg are prepared for children for breakfast, saving time and effort; Third, the cost performance is high, and milk and eggs are cheap. As for the sandwich he mentioned, it is a kind of mixed food containing protein, vegetables and cereals. Although it is imported, it is not much different from China’s pancake fruit, egg-filled cake, burrito and Chinese hamburger in essence. However, most Chinese breakfasts need to be cooked on the spot and eaten while they are hot. The convenience of sandwiches is that they can be kept in cold storage in advance and heated in the microwave oven at breakfast.

　　Nutrition guidance

　　A healthy breakfast contains at least three kinds of food.

　　According to the Dietary Guidelines for School-age Children, a nutritious breakfast should include at least three or more kinds of food. Cereals and potatoes: cereals and potatoes, such as steamed bread, rolls, bread, rice, rice noodles, etc. Meat and eggs: fish, poultry and other foods, such as eggs, pork, beef, chicken and so on; Milk beans: milk and its products, beans and their products, such as milk, yogurt, soybean milk, bean curd, etc. Fruits and vegetables: fresh fruits and vegetables, such as spinach, tomatoes, cucumbers, broccoli, apples, pears, bananas, etc.

　　Specifically, the clear arrangement is: 1 cup of milk of about 300ml, 1 boiled egg; Try to choose solid food as the staple food, and mix it with coarse grains, such as coarse grain steamed bread, whole wheat bread, corn cake, steamed sweet potato and yam. Fruits and vegetables can be tomatoes the size of a fist or other vegetables of the same weight.

　　If breakfast is a mixture of protein, carbohydrate and fat, such as steamed stuffed bun, sandwich, beef noodles and rice noodles, the quantity of vegetables, eggs and milk can be flexibly adjusted according to the above breakfast mode. (Author: nutritionist, China-Japan Friendship Hospital)

Guangdong strengthens the prevention and control of liquidity risk of provident fund, and sets 85% of individual housing loan rate of housing provident fund as the critical point of early warning.

　　On the 28th, the reporter learned from the Guiding Opinions on Early Warning and Management of Liquidity Risk of Housing Provident Fund Funds in Guangdong Province issued by the Provincial Department of Housing and Urban-Rural Development that Guangdong will establish an early warning and management system for liquidity risk of housing provident fund funds.

　　According to the requirements of opinions, through the early warning indicators of individual housing loan rate and net capital flow of housing provident fund, we will comprehensively analyze the capital flow of housing provident fund in time and predict the development trend of supply and demand of housing provident fund loans, and implement early warning in the city as a unit. At the same time, the implementation of early warning classification management. According to the operation of funds and referring to the relevant provisions of the state, 85% of the individual housing loan rate of housing provident fund is set as the critical point of early warning, and it is divided into three early warning levels according to the early warning level: the first warning is that the individual housing loan rate of housing provident fund is between 85% and 90%, and the net flow of funds is negative for three consecutive months; The second warning is that the personal housing loan rate of housing provident fund is between 90% and 95%, and the net flow of funds continues to be negative; The third-level warning is that the personal housing loan rate of housing provident fund is above 95%, and the net flow of funds continues to be negative. When the two early warning indicators of individual housing loan rate and net capital flow meet the conditions at the same time, the corresponding early warning level is triggered.

　　The opinion calls for early warning and management of capital liquidity risk. The Provincial Department of Housing and Urban-Rural Development has established a monthly housing provident fund system through the relevant data of the housing provident fund statistical information system and other relevant data, carried out analysis on the operation of relevant business indicators, monitored the liquidity risk of housing provident fund funds in various cities, and issued early warning risk tips to urban housing provident fund management committees and housing provident fund management centers when necessary.

Expert： The United States is trying to reorganize the Arab version of NATO and wants to ＂kill with a knife＂ to contain Iran.

　　CCTV News:America is out of the group again! On the 3rd, just after the International Court of Justice ruled that Iran had won the lawsuit against the United States, the United States withdrew from the US-Iran friendship treaty. For the rapidly deteriorating relationship between the United States and Iran, withdrawing from the group is only the beginning.

　　In May this year, the United States announced its withdrawal from the comprehensive agreement on the Iranian nuclear issue and restarted sanctions against Iraq. In July, Iran filed a complaint against the United States to the United Nations International Court of Justice, based on the Treaty of Friendship, Economic Relations and Consular Rights signed by the two countries in 1955.

　　On October 3, the International Court of Justice issued a communique saying that it was initially determined that the International Court of Justice had "jurisdiction" over the case and demanded that the United States immediately stop sanctions against Iranian humanitarian goods and goods and services related to civil aviation safety.

　　Iranian Foreign Minister Zarif welcomed the decision in a social media post on the 3rd, calling it "another failure to sanction the addicted United States" and "a victory of legal order".

　　If the ruling of the International Court of Justice is implemented, it will greatly alleviate Iran’s economic difficulties. Because following a series of sanctions against non-energy fields in August this year, the United States will restart sanctions against Iran’s energy industry, oil trading, central bank trading and other fields on November 5, and the situation is urgent.

　　However, after the ruling was announced by the International Court of Justice, Pompeo immediately said that the US-Iran friendship treaty was terminated, and pointed out that Iran’s past "malicious behavior" made it "absurd" to file a lawsuit in the International Court of Justice.

　　According to a report on the website of "Russian TV Today" on the 4th, the 10-year US military aid plan for Israel will come into effect on the 8th and will be implemented in the new fiscal year. Israeli Prime Minister Benjamin Netanyahu welcomes this.

　　On September 14th, the United States and Israel formally signed a new memorandum of understanding, which finalized what was called "the largest single bilateral military assistance in American history".

　　According to this new agreement, from the fiscal year of 2019 to 2028, Israel will receive about 3.8 billion U.S. dollars in aid each year, including 3.3 billion U.S. dollars in foreign military financing and 500 million U.S. dollars in missile defense cooperation program, provided that it must purchase American weapons. The State Council bluntly said that the plan aims to protect Israel from "all potential regional rivals", but the most important thing is to avoid the influence of "terrorist organizations sponsored by the Iranian regime".

　　Li Shaoxian, dean of the Institute of Arab Countries in China, Ningxia University, said that recently, the United States has been trying its best to reorganize the so-called Arab version of NATO, and one of its important purposes is to "kill people by the sword" to contain Iran.

Experts discuss ＂Fireworks Family＂ Xu Fan Liang Jing Sun Qian interprets the core of the role.


1905 movie network news A seminar on TV series "Fireworks Family" was held in Beijing a few days ago. The competent departments, experts and scholars, broadcasting platforms, representatives of the main creators, starring actors, actors and actresses attended the event. The guests at the meeting discussed the spiritual theme of family growth, the cultural communication value of caring for family reality, and the creative concept, development and changes of family dramas with realistic themes.　


"Fireworks Family" takes the getting along, running-in and common growth of three generations of Meng family as the narrative basis, focuses on different intergenerational parent-child communication modes and typical Chinese mother-daughter relationship, and shows the influence of different family appearances on individuals.


Yang Xiaopei, founder and CEO of Xixi Film, artistic director and chief producer of Fireworks House, said when interpreting the creation process of the drama series: "We all experience these trivial things, but how can we still have hope in these trivial lives? This is a core strength and value that I want to express most in the creation of Fireworks House."


After the broadcast of "Fireworks Family", the distinctive characters of the main characters and the plot of dramatic conflict have caused extensive discussions on the Internet. Xu Fan, the actor of Meng Mingwei in the play, shared that the cooperation between the actors in the whole shooting process was very tacit, just like a harmonious big family giving to each other. "There was a scene where my daughter and mother advised Mingwei to divorce. When I looked into my eyes, I felt absorbed and felt the mutual strength between the actors."


Liang Jing, who plays Meng Yuqing, feels the influence of this woman. In her view, the characters have both a sense of fragility and an absolutely powerful inner world, and at the same time, she knows how to get along with her family. Qian Sun, the actor of Tao Shu-na, also expressed her feelings: "Nana infected the audience with her optimism and courage. Many people said that she was me. I used to feel this way when shooting, but later I found that I was more positive and sunny at that time. This is the energy that Nana gave me."


The guests and scholars at the meeting also put forward their research and thinking on Fireworks House. Hujie, Secretary-General of Youth Working Committee of China TV Drama Production Industry Association, said: "From the narrative type, Fireworks Family has opened up a new paradigm of realistic family drama". In his view, while presenting the family relationship in a panoramic way, the play tells the plight of each individual in the family in a delicate and unique way, which is true, grounded and has the texture of real life flow.


Lv Fan, director of the Audio & Video Office of Peking University Media Center and deputy director of Peking University TV Research Center, thinks that Fireworks Family has achieved three things in terms of aesthetic characteristics: it has returned to the realistic tradition of China family drama, realistically represented the essence of female group images and innovated the connotation expression of the word "fireworks".


Professor Tsinghua University, vice-chairman of the Chinese Literary Critics Association, thinks that "Fireworks Family" is a drama that has been widely concerned by the society and brought about a wide range of social topics. It is a new expansion of family ethics drama. The three generations of female images have their own characteristics, and it is also a breakthrough in the new image of new women. Through a new understanding of the new society, the basic theme of upward goodness has been conveyed. "


Liu Qiong, deputy director of the Literature and Art Department of People’s Daily, said in his speech: "This drama has a particularly distinctive female perspective and female thinking, and it interprets and presents the life state with women as the protagonist. It is of exemplary value in large theme types."


Decode the ＂end-to-end＂ concept that everyone is talking about, and easily play with the new trend of automotive technology.

Since the launch of the end-to-end intelligent driving system "FSD V12 beta" in the United States in August 2023, end-to-end has become the hottest topic in the automobile industry. With the follow-up of Huawei, Tucki, Weilai, Ideality and other enterprises, almost every domestic manufacturer will spend a lot of space in the press conference to publicize how powerful their end-to-end is. Regardless of marketing methods, what does "end-to-end" mean? What does it mean for intelligent driving? Today we will explain this question to you!

Before the end-to-end intelligent driving system was mass-produced, every intelligent driving system adopted a modular scheme. Simply put, modular intelligent driving is an assembly line, which mainly includes four processes: perception, prediction, planning and control. First of all, the task of the sensing part is to process the data of sensors such as radar and camera of the vehicle, and then analyze the specific position and road trajectory of the objects around the vehicle, and distinguish whether they are pedestrians, bicycles, cars or trucks.

Then, the perception module will transmit the above information to the prediction module, and the prediction module will analyze the next movement state of the surrounding traffic participants according to the above information, such as whether the surrounding vehicles will turn, go straight or stop next. After further analysis, the prediction module will provide one or more driving paths and vehicle speeds that the vehicle can refer to next.

Then the prediction module sends the road driving scheme of the vehicle to the planning module, and the planning module will decide what the vehicle should do next according to the information such as the vehicle’s own state and navigation. After the planning module confirms the driving path and speed, it will transmit the command to the control module, and then the control module will calculate and operate the steering wheel, brake and throttle of the vehicle. A seemingly simple intelligent driving function is realized through the above steps.

From the above introduction, it is not difficult to see that modular intelligent driving decomposes simple driving behavior into multiple steps, and the logic of each step is in perfect harmony. In the eyes of car companies and suppliers, modular intelligent driving itself is a very good solution, because different teams can be responsible for the corresponding modules and give full play to the advantages of division of labor and cooperation, thus rapidly changing intelligent driving from concept to mass production.

Secondly, modular intelligent driving has a set of system framework with clear functions and responsibilities, so when the intelligent driving system finds bugs in use, car companies and suppliers can immediately find the specific reasons for the bugs and quickly fix them through OTA. For example, if the vehicle brakes wrongly when driving at high speed, then through data analysis, the vehicle enterprise can know whether the fault is due to the wrong data of the sensing module or the wrong judgment given by the forecasting and planning module.

Although modular intelligent driving is convenient for mass production and BUG repair, it needs to learn a lot of traffic rules and driving experience if it wants to control vehicles like people, and all this depends on engineers to define the rules in advance, that is, to turn traffic rules and driving experience into lines of software code. But can engineers write code to cover all the driving scenes in reality? Of course it’s impossible! On this issue, there is a classic case in the industry. If you drive a vehicle on a narrow road full of cars on both sides, a balloon suddenly floats on one side of the road, then the general logic will think that there may be children jumping out on one side of the road, so the vehicle should brake immediately. However, the same scene is placed on the high speed. If the intelligent driving system still controls the vehicle by braking immediately, it is likely to turn into a rear-end collision. In other words, if engineers don’t define the rules in advance for this kind of driving scene, such as the system doesn’t brake after the balloon is detected at high speed, then the intelligent driving system will have safety risks when it encounters similar scenes.

According to Xpeng Motors, a relatively stable mass production intelligent driving system has about 100,000 rules. And if the intelligent driving system is to be close to the same level as people, it needs to manually write about 1 billion rules. For software engineering development, this is almost impossible. Because of this, we can see that the traditional intelligent driving system will make more or less mistakes in daily use, so that drivers have to intervene.

For the above reasons, car companies that focus on autonomous driving have been trying to solve the problem that traditional intelligent driving needs preset rules, so there is an end-to-end approach. The so-called end-to-end, in fact, is to make all the traditional sub-modules of perception-prediction-planning-control neural network, that is, to replace the traditional algorithms and manually written rules with advanced algorithm models.

Therefore, the end-to-end workflow is quite different from the traditional modular workflow. The traditional modular work sequence is perception-prediction-planning-control in turn, while the end-to-end sequence is sensor data (radar, camera)-neural network-driving parameters (steering wheel, throttle, brake), that is to say, the traditional perception, prediction, planning and control modules are all completed by neural network.

As can be seen from the workflow, the core technology in end-to-end is neural network, and the technology most closely related to neural network is AI. In the past two years, AI has shown great performance in the fields of voice, text, pictures and video, and everyone should have realized it. When the neural network is applied to the car, it means that people can constantly train the intelligent driving system, so that it can learn to adapt to more complex driving environment.

Therefore, at the functional level, the biggest change from end to end is that the system has the ability of autonomous learning, which is a function that traditional modular intelligent driving does not have.In this way, when dealing with all kinds of unexpected real driving scenes, end-to-end can calculate the appropriate rules through neural network, without having to manually write the rules in advance, which also provides a solution for intelligent driving to deal with endless driving scenes in reality.For example, the Tesla FSD V11 version, which didn’t have end-to-end function before, has written more than 300,000 lines of code, while the end-to-end FSD V12 version has directly reduced more than 300,000 lines of code to 2,000 lines, but the performance of FSD V12 is closer to human drivers than V11.

fromIn theory, end-to-end is indeed a very ideal technology, but in practice, end-to-end is not so reliable. This is because people’s understanding of neural networks is still not clear enough at this stage, so people also call neural networks "black boxes". As shown in the above figure, in the white box state, we are very aware of the logical causal relationship between system input/output, but when the input information passes through the black box, people can’t explain why the input information becomes the output information.

For example, when there is an obvious logical error in the intelligent driving system, the vehicle manufacturer can quickly find out which module the problem is, and then manually write a new rule. But in the end-to-end system, car companies do not know which parameter or structure in the complex neural network has problems.

For this reason, the end-to-end intelligent driving system based on neural network can sometimes give reasonable rules in very complicated scenes, but sometimes it will make very low-level mistakes, such as not being able to distinguish traffic lights, so some people describe it as "the upper limit is very high and the lower limit is very low". Considering that there are some risks in the end-to-end application, the end-to-end intelligent driving system introduced by Huawei and Tucki does not rely entirely on autonomous learning, and their end-to-end systems still have many manually written rules to cover the intelligent driving system.

From the perspective of technology development trend, end-to-end is definitely the direction of high-level intelligent driving in the future. However, because people’s understanding of neural networks is not thorough enough, the end-to-end performance of various companies at this stage still has a certain gap with the ideal level. In addition, compared with the existing modular intelligent driving system, whether the end-to-end neural network algorithm model is smart or not depends heavily on massive real data for training. Only after massive data training, the neural network can be transformed from a small model to a usable large model, which means that high-order intelligent driving requires huge computing power and data input in the development stage, thus invisibly raising the threshold of intelligent driving. Because of this, some car owners will feedback that their cars are not as good as they used to be after upgrading to end-to-end intelligent driving. This is the painful period of big model training. Considering that there are great differences in end-to-end training among different brands in reality, this means that the performance gap of different brands of intelligent driving systems may be gradually widened in the future.

Can the end-to-end model solve the last mile problem of autonomous driving？

In smart car technology, high-level autonomous driving is a difficult problem that major manufacturers and most Internet giants are trying to overcome. Whoever can take the lead in promoting the landing of advanced autonomous driving technology will be able to take the lead in automobile sales. In the high-order autonomous driving technology, the end-to-end model is the most discussed by all parties.

Compared with the previous model, end-to-end seems to have become the only way for advanced autonomous driving. So what is the end-to-end model? What is the development trend of end-to-end model in China? These problems are worthy of people’s attention.

What is an end-to-end model?

Speaking of the end-to-end model, it is natural to be inseparable from the ChatGPT of this year’s fire. ChatGPT itself is an end-to-end model, that is, by inputting words, customers can get the answers they want.

Whether it’s PPT or video, ChatGPT and other big models may spit it out. In this process, the most critical is the AI model. It can gain insight into users’ needs and produce the content they need.

In the field of autonomous driving, the most famous end-to-end model is Tesla’s FSD V12. The input of this model is all kinds of image data obtained by the camera; The output end is the vehicle control instructions, including steering, acceleration and braking. In the middle, it is a big model that Tesla is proud of.

In the scene of end-to-end model, when the vehicle recognizes some traffic signs or encounters various situations, it will automatically judge according to the past learning situation, instead of looking for a solution to this problem in the code according to various preset preconditions like the traditional model.

What are the advantages of the end-to-end model?

In contrast, in the past, the traditional autopilot model was based on the working conditions set by engineers in advance. The choice of driving behaviors, including lane changing, parking and even overtaking, has been set in advance. This will bring two problems:

Autopilot models are becoming more and more complex. Since each module usually only performs one driving behavior, the automatic driving algorithm needs to include the driving behavior of human drivers as much as possible. Therefore, the code of traditional autonomous driving technology usually has hundreds of thousands of lines of code. This will bring higher and higher requirements for the computing power of smart driving chips. Tesla’s FSD V12 has only 2000 lines of code; While FSD V11 has an astonishing 300,000 lines of code.

Unable to solve the long tail condition. No matter how full the preliminary test and certification are, no autopilot algorithm can say that all the long tail conditions are included. Then once you meet a new long tail working condition, it is very likely that traffic accidents will occur and even life injury accidents will occur.

The best case is that the project operated by GM’s Cruise in California encountered various working conditions that had not been encountered in the previous experimental stage at the beginning of its launch, which led to casualties, forcing the California Highway Bureau to suspend the license of Cruise for a time.

Where is the end-to-end difficulty?

To achieve an end-to-end model, there are two main limiting factors: massive data and large computing power. Only with the blessing of these two factors can the end-to-end model land. In order to make the end-to-end model closer to human drivers, its large model often needs to contain hundreds of millions of parameters. Only with more parameters can the driving characteristics and habits of human drivers be better simulated, and the performance of the model will be better. In these two areas, Tesla has a clear first-Mover advantage.

Not long ago, Tesla just got the certification of domestic data security and privacy protection, and was allowed to enter the government department compound. The reason why Tesla didn’t get the relevant recognition before was that the cameras in each car were collecting all kinds of data in real time and uploading them to the server for training the FSD algorithm.

Looking around the world, Tesla’s newly sold models every year are constantly providing data for the FSD V12 algorithm for the latter to continue to optimize learning.

It is worth mentioning that Tesla’s car also has a "shadow mode". It will compare the deviation between the driving behavior of the owner and the driving behavior determined by the automatic driving system, upload the relevant data together, and also optimize the algorithm.

At the same time, in order to be able to calculate the massive data collected, Tesla also needs a supercomputer center. The core of supercomputing center is the large computing power chip. For this reason, Tesla not only bought a large number of NVIDIA H100 chips, but even developed Dojo chips. The unit price of the former is as high as $35,000, while the investment in research and development costs of the latter is hundreds of millions.

For any enterprise, this is not a small expense. Domestic car companies have basically not been able to develop their own large computing chips. NVIDIA H100 chip has already become a product on the export control list of the United States, and it is difficult for domestic car companies to obtain it.

So is it possible to achieve the end-to-end model with massive data and large computing power? The answer is also no.

From the above description, we can find that the end-to-end model is actually a "black box". If there is an error in the model operation, it is actually difficult for researchers to find out what part of the model is wrong and directly adjust the model.

Theoretically, only through more training, or increasing more parameters and trying to adjust some model parameters can we try to solve the problem. Therefore, whether the autopilot model based on end-to-end technology can finally meet the needs of autopilot technology at the safety level is still very uncertain.

Even so, compared with the traditional autopilot model, the advantages of the end-to-end model are very obvious. Especially when solving the long tail condition, the end-to-end model can give play to the incomparable advantages of the traditional autonomous driving technology model. At present, some new car companies, such as Huawei, Tucki, Weilai and Ideality, have started to introduce the end-to-end model in the domestic market.

Aside from Huawei, which has abundant capital, it is a big challenge for new car companies with limited capital accumulation to balance the input and output returns of end-to-end technology. Not to mention, it is not an easy task to buy large computing chips in China at present.

With the high probability of the end of the year, Tesla FSD V12 will enter the domestic market. What changes will take place in the domestic market structure of autonomous driving technology at that time, which deserves people’s attention.
