The Dream of China, starring Liu Yifei, Chen Xiao, Joe, Ada and Jelly Lin, has been very popular recently, and its popularity continues to rise. Meng Hua Lu was adapted from Guan Hanqing’s zaju script Zhao Paner’s romantic rescue.

The background of the story takes place in the Song Dynasty, and the costumes in the play are extremely excellent and elegant, vividly and skillfully highlighting the personality characteristics of the characters. No matter the actors, themes, costumes and plots are excellent, the actress’s shots in this film are even more exquisite and praised by the audience. Of course, all this is indispensable to the credit of lens language design.

Meng Hua Lu has made great efforts in the design and expression of lens language, showing the scenes and characters vividly. The shooting of the whole film is very skillful, and the lens language and picture are very beautiful, artistic, full of meaning and endless charm, presenting pleasing visual effects and bringing excellent visual experience to the audience.

The lineup of Meng Hua Lu is luxurious. The photography director is Yiqin, a senior photographer from Taiwan, China. Director Yang Yang is a famous female directors in China, a national first-class director, and his works have won various awards. The two men joined forces to integrate the theme of the film and the expression of characters’ emotions into the lens language, so that the quality and standard of Dream of China by going up one flight of stairs presented an excellent work to the audience.

In the beginning, Zhao Paner came slowly with a row of bamboo rafts in the distance, his hands alternately swaying bamboo paddles, the breeze blowing gently, the lake waves rippling, and a peaceful and pleasant scene of Jiangnan water town jumped from the paper, giving people an immersive feeling. "arm in arm to punt, the beautiful lake swings."

The camera will play Liu Yifei, the "fairy sister" of Zhao Paner. It is gentle but smart, elegant but atmospheric. This clip has made many viewers watch it again and again, immersed in enjoying this unique beauty like a fairy.

In the fifth episode of the play, the man and the woman talked about drinking, and the wine strength came up, and the eyes looking at each other also changed. Camera switching, a moment to Zhao Paner, I saw her chin staring, charming eyes, a moment to Gu Qianfan, I saw him staring, eyes tender, cut to two people in the same frame, the two sides stared at each other, rendering a subtle atmosphere, at this time, the psychological activities and relations between the two people, can be said to be self-evident.

When parting, the camera switches back and forth between the two. Zhao Paner stood on the small building, Gu Qianfan sat on the boat, and their eyes were reluctant and thoughtful. Zhao Paner eyes flow, tenderness, never removed from Qian Fan, always looked at the boat.

In the face of Zhao Paner’s eyes, Gu Qianfan gradually ignored the words of his peers and didn’t listen to them. When he turned to visit the small building, Zhao Paner’s eyes were still gentle and watery, as if penetrating his heart. At a loss, he had to avoid looking, but he couldn’t help looking in the direction of the pavilion from time to time, showing nostalgia and concern.

Moonlight gently sprinkled on the lake, lingering and lingering, and Zhao Paner watched the boat go away. "whose boat is flat tonight, where to miss the bright moon building." Silent language, with only two people’s eyes and natural scenery, expresses implicit love, which makes people feel unfinished.

The conversation under the umbrella in episode 6, scene selection and composition are very interesting. The background environment is rainy, and the umbrella held by the man and the woman is used to isolate other people in the same space. The camera focuses on the two people, highlighting the main body, making the background completely in Jiao Wai, which enriches the three-dimensional sense of the picture, meaning that this moment is the time exclusively for the two of them, providing a unique space for the next two people to talk.

The raindrops pattering on the umbrella not only created a cold atmosphere, but also narrowed the distance between them, bringing out the psychological changes of the man and the woman, and making them feel depressed. "Holding hands and looking at tears, I was speechless."

The emotion expressed in this lens language is very rich. The concern, awkwardness, pulling and attachment of two people, each picture conveys different emotions to the audience.

On the moon, the willow shoots, and people meet after dusk. In the evening, the sun is setting in the west, and they flirt. When crossing the bridge, Zhao Paner was holding a paper umbrella, and the man was holding the box, chatting while walking, his eyes staring at each other. Although it is a distant vision, there is no voice of conversation between them, but the distance between them and the direction in which their eyes look fully show their mood and relationship at this time.

This shot is poetic and picturesque, and I can’t get tired of watching it. Only a few seconds of a silhouette shot, full of story, made many viewers pause to enjoy this beautiful and romantic scene, and was also made into wallpaper by screenshots.

Meng Hua Lu, whether it is the lens language or the script lines, is carefully polished. The picture is no longer a ten-stage skinning beauty filter for domestic dramas. The lines are properly worded and flowing, the plot is fascinating and natural, and the actors’ acting skills are up to standard without any serious injuries.

Although the recent online comments on Meng Hua Lu are mixed, it is full of some discordant remarks. But on the whole, the film is exquisite in production, high in quality, picturesque and beautiful in picture, and the lens design is rich in layers and originality, which is very worth seeing!

In 2003, highly pathogenic avian influenza (HPAI) broke out in Southeast Asia. Until recently, HPAI only broke out in Indonesia, Viet Nam, Thailand, Laos, Cambodia and China and other eastern Asian countries. But from April to June, 2005, more than 6,000 migratory birds died of H5N1 in Qinghai Lake, China. In July 2005, H5N1 outbreaks also occurred in Russia and Kazakhstan. In August, 2005, a wild bird died of H5N1 in a lake area in northern Mongolia. In October 2005, poultry or wild birds infected with H5N1 were also detected in European countries such as Turkey, Romania, Greece, Sweden and Britain. The H5N1 avian influenza epidemic broke out in Anhui, Hunan and Liaoning. This worldwide outbreak of avian influenza has caused a large number of poultry to be killed and infected people. As of November 2, 2005, 122 people have been found to be infected with H5N1, of which 62 died [1]. The worldwide outbreak of H5N1 highly pathogenic avian influenza has caused great losses to agriculture and aquaculture, posed a serious threat to human life safety, and attracted worldwide attention. The worldwide outbreak of HPAI can easily remind people of the role of migratory birds in the spread of avian influenza, because migratory birds have the ability of long-distance migration across national boundaries, and they are regarded as a major carrier of avian influenza virus. However, based on the existing facts, it is still difficult to determine the role of migratory birds in the spread of avian influenza.The outbreak of avian influenza in 2005 showed some characteristics different from previous outbreaks. The research work is still going on. Although the role of wild birds in the spread of avian influenza is still controversial, it is urgent to establish a monitoring network for wild birds and conduct a dynamic study on the epidemiology of avian influenza virus.

1 influenza virus characteristics

Avian influenza virus belongs to Orthomyxoviridae. According to nuclear protein (NP) and membrane protein (M1), it can be divided into three types: A, B and C. According to hemagglutinin (HA) and neuraminidase (NA), influenza A virus is further divided into subtype 2. Up to now, 16 HA (H1-H16) and 9 NA (N1-N9) influenza virus subtypes have been found, and H5N1 is one of the virus subtypes 3.

According to the pathogenicity, avian influenza viruses can be divided into HPAI and LPAI (low pathogenicity avian influenza virus). LPAI is often parasitic in the respiratory and digestive systems of birds, and generally does not cause pathological reactions, or only causes mild pathological symptoms. However, HPAI can infect various tissues and cells of the host, causing various organs of the host to fail, leading to death, and its mortality rate is as high as 100%. Up to now, all the HPAI found are H5 and H7 subtype influenza viruses. LPAI can be transformed into HPAI4 through the change of amino acid site in HA0 cleavage region.

Influenza A virus has been isolated from many animals, including humans, pigs, horses, seals and wild birds. The phylogenetic study of influenza A virus found that influenza A virus has host interspecific relationship, and other animal influenza A viruses originated from waterfowl influenza A virus 5.

The wild migratory birds themselves are the natural reservoir of bird flu.

All virus subtypes of 16 kinds of HA and 9 kinds of NA have been found in aquatic bird populations. Stakkknecht and Shane isolated 2,317 strains of virus from 21,318 birds, with a carrying rate of 10.9%, including 14,303 birds of the order Animalia, and 2,173 strains of virus were detected (15.2%). Except for geese and ducks, the carrying rate of influenza virus in other birds was only (2.1%) 6. It is worth noting that influenza A virus seems to have achieved an ideal parasitic adaptation in the host of wild birds. LPAI is parasitic in the digestive or respiratory system of the host. LPAI isolated from most wild birds is nontoxic, and the host has no symptoms or only mild symptoms. The transmission between birds can be directly or indirectly through dust, water, food and other pollutants contaminated by feces. LPAI may be transmitted to poultry through contact between wild birds and poultry, and mutate in poultry population, leading to HPAI. Poultry infected with HPAI can lead to systemic infection. Clinical symptoms include decreased egg production, dyspnea, excessive tears, brain edema, diarrhea and neurological symptoms that eventually lead to death. But so far, there is no more evidence to prove that wild birds are natural reservoir of HPAI. Therefore, there is a theory of HPAI outbreak mechanism that only when LPAI in wild waterfowl spreads to poultry such as chickens or turkeys, and LPAI mutates into HPAI in poultry, will it lead to the outbreak of highly pathogenic avian influenza. Since 1959,There were 19 incidents in which LPAI from wild birds was transmitted to poultry and mutated into HPAI in poultry, which eventually led to the outbreak of the epidemic.

3 Debate about Wild Birds as Spreaders of HPAI

It is precisely because wild birds are the natural reservoir of avian influenza virus, and the migratory route of migratory birds can obviously connect Asian countries with the outbreak points of H5N1 avian influenza in Siberia, Kazakhstan and Europe. Therefore, when HPAI was raging, some people suspected that migratory birds were spreading the bird flu virus. But so far, no clear source of H5N1 HPAI that ravaged Asia in 2005 has been found. It is speculated that before the outbreak of HPAI in domestic chickens in Hong Kong in 1997, LPAI, the predecessor of this kind of HPAI, might parasitize the wild waterfowl population in southern China and spread and evolve, and then contact with poultry in Hong Kong through some channels. LPAI mutated into HPAI and broke out in 2003. The Hong Kong government controlled the outbreak of bird flu by killing 1.5 million poultry. Then, in December 2003, the virus once again ravaged Korean chicken farms. Outbreaks in Japan and Vietnam in January 2004; An epidemic was discovered in Indonesia in February; It soon led to outbreaks in Thailand and China.

But many ornithologists doubt the hypothesis that wild birds infect avian influenza. First, since the late 1990s, the United States Department of Agriculture has detected tens of thousands of migratory birds migrating from Asia to Alaska, and Hong Kong researchers have also sampled thousands of inbound migratory birds, but none of these tens of thousands of wild bird samples have detected H5N1 subtype. Up to now, the research results show that the H5N1 strain that causes high mortality of poultry is also pathogenic to wild birds. Wild birds infected with HPAI will also get sick and die. When the host dies, the spread of the virus stops, and the spread chain of the virus is interrupted. Secondly, the transmission path and outbreak time of avian influenza are not very consistent with the migration path and migration time of migratory birds. Although wild birds are the natural reservoir of avian influenza, it is not entirely accurate to blame wild birds for the outbreak of HPAI. Because in addition to the migration of migratory birds, bird flu may be spread, the backward feeding methods of mixing livestock and poultry with wild birds provide an ideal environment for the mutation and breeding of bird flu virus, and human activities such as frequent poultry trade and wildlife smuggling may play an unimaginable role in the spread of the virus. For example, in January 2004, an outbreak of H5N1 occurred in Lhasa, Xizang, which was finally found to be caused by selling a batch of sick poultry from Lanzhou, Gansu, 1500 kilometers away to Lhasa. An even more surprising incident occurred in Brussels. In October 2004, two crested eagles smuggled into Belgium from Bangkok Bird Market were seized at Brussels Airport.And detected that it has been infected with H5N1 virus. Therefore, many biologists are skeptical about the hypothesis that migratory birds spread avian influenza virus.

While people are arguing about the role of wild birds in the spread of avian influenza, the H5N1 outbreak in 2005 showed several aspects different from previous epidemics. Until the spring of 2005, there had not been any death of wild birds infected with H5N1 virus. However, in April 2005, the H5N1 outbreak in Qinghai Lake killed more than 6,000 migratory birds. At present, researchers are still investigating the causes and possible consequences of the outbreak of H5N1 in Qinghai Lake.

Then in August, 2005, wild birds in Lake Irkher in Mongolia also died of H5N1 infection. There are few poultry farms in Lake Irhull. It is likely that wild birds infected with H5N1 brought the virus to Lake Irhull, and the US Department of Agriculture only detected H5N1 strains in dead birds, but not in other living ducks, gulls, geese and swans. It is not known which kind of birds spread the virus, which may be very difficult, because there is very little research work on avian influenza virus in other birds except waterfowl. While the research work is still in progress, in October 2005, several European countries in Caspian Sea, Black Sea and Mediterranean Sea broke out one after another, which made more and more people believe that wild birds played a role in the spread of avian influenza.

In October 2005, an outbreak of avian influenza occurred in Hunan, Anhui and Liaoning, and the state took decisive measures to control the epidemic. Some experts said that the epidemic focus may come from migratory birds 9.

4. Establish a wild bird influenza virus monitoring network and strengthen

Protection of wild bird resources

While the role of wild birds in the transmission of avian influenza is still controversial, Europe has begun to establish a European-wide investigation and monitoring network for wild birds. Researchers in the Netherlands have collected more than 6,000 bird samples on the migration routes of European migratory birds. The monitoring network is not only to study the role of wild birds in the spread of avian influenza, but also to monitor the changing direction of avian influenza epidemic, study the variation law of avian influenza virus, and provide valuable data for preventing the outbreak of avian influenza.

Because all the influenza strains in the history of human influenza outbreaks are new strains formed by the recombination of avian influenza strains and human influenza strains, it is difficult for human immune system to play a role in the face of this new strain, and it is difficult for vaccines based on unchanged strains to play a role in the new strain, so it is easy to trigger human influenza outbreaks, resulting in significant economic losses and human death. The wild bird influenza epidemic monitoring network can not only be used as an early warning network for human influenza outbreaks, but also monitor the variation direction of viruses, providing reliable data for vaccine development, and developing vaccine strains that may cause influenza outbreaks before influenza outbreaks, thus changing the previous practice that vaccines can only be developed after influenza outbreaks. In addition, this monitoring network can also monitor the changes of antiviral drug resistance of viruses for a long time to ensure the effectiveness of antiviral drugs in the emergency of influenza outbreak. At present, it has been found that avian influenza virus has developed resistance to interferents based on hemagglutinin (such as amantadine); The interferents developed based on neuraminidase mainly include Tamiflu produced by Roche and Rekenza produced by Gkaxo Smith Kkine. Recent studies have found that influenza virus has produced a few resistance to Tamiflu, while Rekenza has not found any record of resistance because of its low dosage. Therefore, governments around the world should pay attention to the problem of drug resistance while stockpiling antiviral drugs. Use the monitoring network to monitor the virus for a long time,The problem of drug failure caused by drug resistance can be found in time.

Therefore, it is of great significance to establish an influenza surveillance network for wild birds. In the face of severe avian influenza epidemic, China should immediately set up its own wild bird monitoring network, study the role of wild birds in the outbreak of avian influenza, find key hosts, study the transformation and variation law between LPAI and HPAI, monitor the direction of virus variation, and provide reference for vaccine development, and monitor the change of virus resistance, so as to provide reference for the development and storage of antiviral drugs.

5 conclusion

The role of wild birds in the spread and outbreak of avian influenza is still controversial. By analyzing the existing evidence, it is still impossible to confirm the role played by wild migratory birds in the spread of avian influenza. After more than one year’s molecular epidemiological investigation of avian influenza, although it has not been confirmed that wild birds are natural reservoir of HPAI, it can be confirmed that wild birds can be infected with HPAI H5N1 virus, not only migratory birds but also resident birds. All kinds of facts remind us that the outbreak and epidemic of HPAI H5N1 in the world may include the repeated transmission link of "wild birds → poultry → wild birds → poultry", and each host transfer and repetition may enhance the toxicity of the virus.

LPAI can mutate cyclically in poultry and wild birds until the HPAI epidemic occurs. HPAI virus is fatal to poultry and wild birds that originated in the first place. Infected wild birds are often dying or dying, which may affect their ability to spread the virus over a long distance. The fact that migratory birds in Qinghai Lake are infected with avian influenza reveals that H5N1 virus can spread among wild birds. However, these viruses are collected from dead or dying individuals, and they are the ultimate hosts. The further monitoring results of migratory birds that survived the bird flu control in Qinghai Lake will prove whether it is possible for migratory birds in Qinghai Lake to spread the virus with migration. At present, before we fully understand the role of migratory bird migration in the process of bird flu transmission, we should not blindly assume that HPAI has nothing to do with migratory bird migration, nor should we ignore the role of migratory bird migration in bird flu transmission. In addition, a very important point is often overlooked by everyone, that is, keeping birds. Previous studies mainly focused on migratory birds, and recently HPAI virus was detected in resident birds. If HPAI H5N1 can be isolated from a large number of healthy birds, it will be the biggest threat for human beings to prevent and control avian influenza.

From the perspective of logistics, environment and biodiversity, it is difficult to control avian influenza infection in wild birds at this stage. Indiscriminately killing wild birds is ineffective in preventing the spread of avian influenza, and it is likely to cause the extinction of wild birds.

In addition to paying attention to the role of wild birds in avian influenza, limiting the contact between poultry and wild birds should be a key part of avian influenza prevention strategy. We should reduce the contact between people, poultry and wild birds as much as possible, improve the level of poultry raising and avoid free-range; Strictly manage the poultry and wildlife trading market; Strengthen quarantine and immunization work; Put an end to illegal unlicensed poultry and wildlife trade.

In order to prevent the spread of HPAI, it is urgent to carry out scientific research on wildlife diseases. Establish a monitoring network for avian influenza in poultry and wild birds. Monitoring, sampling and analyzing the evolution and variation of avian influenza subtype virus in wild birds. Establish and improve the laboratory research ability to quickly detect and analyze the characteristics and types of viruses. Establish a perfect monitoring network of wild bird epidemic focus in order to quickly respond to virus emergencies and provide timely reference for national decision-making. Long-term monitoring and detection of avian influenza epidemic situation. Investigate the wild host distribution of avian influenza virus, study the variation law of the virus, determine the distribution, types and natural history of avian influenza virus in wild birds, and explore the relationship between wild migratory birds and agriculture and aquaculture structure and its role in the transmission of avian influenza virus to poultry and people. Develop and reserve safe vaccines and antiviral drugs against avian influenza virus. Organize veterinarians, wildlife experts, ornithologists, virologists, molecular biologists and other multidisciplinary experts to jointly study the changing law of avian influenza, fully understand the role of wild birds in the spread and spread of avian influenza virus, and prevent the outbreak of avian influenza and human influenza.

　　On April 14th, 2012, in Chengdu, the students who took the Olympic Mathematics Examination walked out of the examination room. (Information photo photography Wu Xiaochuan)

　　Who is the Olympics suitable for?

　　Chen Ping, an expert on the proposition of the National Primary School Olympiad 4 Cup, believes that only 5% of the people are suitable for Olympic math training & mdash; 8%。 Even if the National People’s Congress is attached to the middle school, less than 15% of the students are suitable.

　　Teacher Fan of Southwest Jiaotong University believes that whether primary school students are suitable for learning Olympic Mathematics should not be simply based on math scores.

　　There is something wrong with olympiad

　　Chen Ping believes that the current penetration rate of the Olympic Mathematical Market has far exceeded the reasonable range, which is not beneficial to unsuitable students.

　　In addition, the Olympic Mathematics is only a supplement to the expansion of school learning, and should not be used as an indicator for further studies.

　　Recently, a post about elementary school olympiad was frequently forwarded in the circle of friends. After reading the post, many people shouted "the topic is poisonous", and some netizens vomited, "Is this to train students into a neurotic patient?"

　　For being "hacked" again, many Olympic math teachers even called "lying guns". Chen Ping, director of the National Organizing Committee for Exploring the Mathematics Garden (Spring Cup), clarified to the reporter of Huaxi Dushi Bao that the topics in the post are not Olympic math questions — — This "Olympiad Mathematics in Primary School" question is adapted from some IQ tests in the early years of the United States.

　　In response to Olympiad Education’s query, Chen Ping said frankly that only 5% of the students are suitable for Olympic Mathematics training & mdash; 8%, but at present, the penetration rate of the Olympic Games market has far exceeded the reasonable range, which is not good for unsuitable students.

　　In addition, Teacher Fan, who teaches mathematics at Southwest Jiaotong University, believes that whether primary school students are suitable for learning Olympic Mathematics should not simply examine their math scores, but also their reaction and interest in math problems.

　　Shentie

　　Recently, a post about primary school Olympic math was frequently forwarded in the circle of friends, and parents vomited: this Olympic math problem is too unusual. Look — —

　　How many questions can you do correctly in this "Primary School Olympiad"?

　　1. (Jiangsu Nanjing Grade Four) Observe the following Chinese characters and find the rules to fill in the blanks.

　　Ligan and Tian A, Feng B, Lin C, Huo D, Shan

　　"Is this really a math problem?" The netizen picked up his skull, "‘ Force ’ 2 pens, ‘ Fuck ’ 3 pens, ‘ And ’ 3 pens, amount … … It seems that strokes don’t work. "

　　The announcement of the answer made everyone "cry": choose A, because every word has a cross structure.

　　The next topic continues to "torment" netizens.

　　2. (Jiangsu Yancheng Grade 4) Observe the following Chinese characters and find the rules to fill in the blanks.

　　Xigang Kouri A, A B, Hui C, Chang D, Tong

　　"strokes? There is no hope. Cross? I didn’t do it How many sections are closed? Who can show me the way! "

　　Seeing the answer, netizens can only "surrender": choose C. The first word has a right angle, the second word has two, the third word has four and the fourth word has eight, so the fifth word must have 16 right angles.

　　"Right angle? Isn’t it for graphics? " "Right angle in Chinese characters? What is this God perspective? " Helpless netizens silently saw the next question:

　　3. (Shandong Jinan Grade 3) Find a rule to fill in the blanks.

　　1，10，5，4，7，，9，6

　　"Well, finally have a math problem. Let me see how the option uses exclusion. "

　　Options: A, I B, Love C, Count D, Learn "is a Chinese character? Does the stroke of the word represent the answer? For example, ‘ I ’ It is 7 paintings and the answer is 7, so choose A. "

　　After thinking hard, seeing the answer, netizens can’t calm down: choose D. These numbers are arranged in the order of the first sound, the second sound, the third sound and the fourth sound, and "learning" is the second sound.

　　Seeing the last question, the netizen breathed a sigh of relief, "the authentic math problem is coming."

　　4. (Guangdong, Guangzhou, Grade 6) Observe the following figures and find the rules.

　　1，4，3，11，2，0，7，12，6，，8，30…

　　A.9 B.14 C。 -1 D.32 the answer is a. Why? The analysis is as follows: after the topic is changed into English, it is one, four, three, seven, two, zero, seven, twenty, six, eight, thirty… There should be a four-letter word in brackets, and only nine matches it.

　　"Can’t you have a good mathematical solution?" Some netizens left a message, "I still tore up the first prize certificate of the Olympic Mathematics."

　　After the topic was highlighted, the post showed his point of view, "The primary school olympiad is very unhappy — — Too anti-human! " The poster thinks that it is not advisable for children to be immature and impose too many messy things.

　　However, many Olympic math teachers have "cried grievances" about this, saying that the topic in the post is not an Olympic math topic. This time, the brush screen is purely lying down.

　　seek to prove

　　The Olympic math test questions have to be mathematical questions, and these questions have nothing to do with mathematics except simple numerical relations.

　　The IQ test questions are "olympiad" when they are compiled and turned around.

　　If this is not an Olympic math problem, what is it?

　　On September 12th, the reporter of Huaxi Dushi Bao contacted Chen Ping, director of the National Organizing Committee of Mathematics Garden Exploration (Spring Cup), who is now presiding over or participating in three competition propositions in the 4 major primary school Olympic Games, and at the same time providing attractive IQ test questions for many lT and financial enterprises listed on the main board or in the United States.

　　Chen Ping made it clear that the topics in the post are not Olympic math questions. First of all, the Olympic math test questions have to be mathematical questions, and these questions have nothing to do with mathematics except simple numerical relations. Secondly, the Olympic math test questions require rigor and objectivity, and there is only one correct answer, but these questions have more than one correct answer.

　　Tracing back to the source, Chen Ping believes that these questions with the label of elementary school olympiad first came from some IQ test questions in the early years of the United States, and then they were adapted by a few people and copied from each other inside and outside the circle.

　　"IQ test questions are very different from Olympic math questions." Chen Ping said that the Olympic Mathematics is based on mathematics and emphasizes corresponding thinking. Good Olympic Mathematics questions require higher thinking depth. The IQ test questions test the thinking level of participating users in different aspects through different types of questions and different directions. A similar assessment has been made in the early training sea election divination of the middle school affiliated to Beijing People’s Congress. "But it is always used, and the IQ test is not allowed. Now, the IQ tests of the National People’s University High School and the United States are constantly changing. "

　　answer questions

　　What kind of children are suitable for learning Olympic Mathematics? It must be combined with students’ thinking ability, interest level and will quality.

　　Olympic math expert: being tied up for further study is the key to the problem

　　All along, the Olympic Mathematics has been at the forefront. Some people say that it is a good way to exercise thinking, and some people say that it is a villain who tortures students.

　　Ms. Wen’s sons in the sixth grade all scored more than 115 points in mathematics (with a total score of 120 points). She said that the Olympic Mathematics has promoted her son’s interest in mathematics, and he has more ideas to solve problems after learning. Mr. Yu said that in fact, his children are not interested in the Olympic Mathematics. "But considering that they may become extra points when they go to school, let him try to learn."

　　Regarding the current situation of Olympic Mathematics, Chen Ping responded that Olympic Mathematics training was originally aimed at a specific group of people, and only 5%-mdash; 8% of the population. At present, the penetration rate of the Olympic Mathematics market has far exceeded the reasonable range, which is not beneficial to unsuitable students.

　　What kind of children are suitable for learning Olympic Mathematics? Chen Ping said that it depends on students’ thinking ability, interest level and will quality. If students do not meet the requirements, then teachers can only make them memorize, but this is not conducive to the growth of students. In addition, the serious expansion of Olympic Mathematics will also lead to uneven teachers of Olympic Mathematics. In the 1990s, there were only twenty or thirty qualified Olympic math teachers in Beijing, and now there are thousands of them.

　　Finally, Chen Ping bluntly said that the Olympic Mathematics is only an expansion and supplement to on-campus learning, and should not be used as an indicator for further studies.

　　Math teacher: Good math scores may not work.

　　In the Olympic Mathematics class, you can often see the first-year students. In this regard, Teacher Fan, a traffic math teacher in Southwest China, believes that although his children are good at math, they only enrolled in the off-campus math competition training in the next semester of the fifth grade. If parents can’t coach their children, it is recommended to take part in the third and fourth grades. In the primary stage of primary school, we should cultivate other hobbies.

　　"Parents should also evaluate their children’s learning." Teacher Fan believes that the basic knowledge should be paid attention to in the study of Olympic Mathematics, and many students ignore the study of definition concepts and only use formulas to solve problems, which can not lay a good mathematical foundation and thus lose the significance of learning.

　　Teacher Fan believes that for primary school students, whether it is suitable to learn Olympic Mathematics should not simply look at their math scores, but also look at their reaction and interest in math problems. Although many practical and careful students can get good grades, they are not sensitive enough to mathematics and are not suitable for participating in competitions.

　　Teacher Fan said that there is no original sin in the Olympiad itself. If it is out of children’s own interest, it is definitely beneficial to learn more. However, once the olympiad is linked to utilitarian purposes such as adding points and winning prizes, it becomes a burden and even a nightmare.

　　Huaxi Dushi Bao reporter Mao Yuting

　　Reporter’s notes

　　Who alienated the Olympiad?

　　Competition mathematics has existed for a long time, and the word "Olympiad Mathematics" was born in the 1960s and 1970s. In line with the Olympic spirit, China children have won many honors internationally. Therefore, parents yearn for a "child prodigy" at home, or force or persuade them to send their children to the Olympics class.

　　Or for the sake of honor, some schools also use Olympiad as an admission index by stealth. As a result, the coverage of the Olympic Games market in first-tier cities has reached 70%. In the interview, Chen Ping bluntly said that even in the middle school attached to the National People’s Congress, it was only 10%— 15% students are suitable for Olympic Mathematics training.

　　But what about the students of "National Olympics"? Some people can’t solve the problem, have a fear of difficulties, and even recite the problem in order to achieve the expected effect.

　　Under the "magic" of the baton, both the child and the Olympiad lost their natural features. Olympiad Mathematics, like music and airplane models, can make children’s thinking grow freely. Once it is linked with utilitarian purposes, it is no longer a specialty and interest that inspires children, but a nightmare that tortures people.

　　Is this the fault of Olympiad? Olympic Mathematics should be regarded as a learning hobby rather than a nightmare in the eyes of some parents and students. There is no original sin in the Olympiad itself, but it is wrong to use it as a "tool" for further study. Let the Olympiad grow freely and let the children grow naturally, which is the purpose of the Olympic Games.

Avatar: The Way of Water (hereinafter referred to as Avatar 2) has been released for a week, and with its shocking and extraordinary audio-visual effects, the global box office has reached 609 million US dollars. Foreign box office analysts predict that the global box office will exceed 1 billion US dollars in about 10 days.

These days, with the first batch of "Yangkang" in China returning to normal work and life, the number of people watching movies is increasing. It is expected that the box office of Avatar 2 in China will grow steadily, and the ticket price is also expected to fall.

Avatar 2 is a super 3D visual blockbuster that James Cameron has sharpened his sword for thirteen years, and it is highly anticipated by fans all over the world. On December 16th, the film was officially released in many countries and regions around the world, and earned $134 million at the box office in North America and RMB 397 million at the box office in China. The global first weekend box office was $434.5 million.

Although this box office achievement is lower than expected, it has set a new box office record for James Cameron’s film in the first weekend. Cameron’s works have always been long-distance runners. Before the release of Titanic and Avatar, the box office was not as good as expected in the first weekend, but in the end, the two films successively topped the global box office champion.

As of December 23rd, the global box office of this film reached 609 million dollars. According to Time. com, some foreign box office analysts predict that Avatar 2 will exceed $1 billion at the box office after the Christmas holiday, that is, within 10 days of its release.

Avatar, which was released 13 years ago, was released in North America until the third week, and the global box office only exceeded $1 billion. From this point of view, Avatar 2′ s current global box office performance is not bad.

Cameron’s own response to the first weekend’s box office query is: We won’t know how Avatar 2 performed at the box office until the third weekend. Now that the director has said so, we will wait and see.

In contrast, the box office performance of Avatar 2 in China mainland film market is far from the expected performance: the first weekend box office was 397 million yuan, and as of December 23 (the eighth day of release), it was 556 million yuan, and it will exceed 600 million yuan today.

However, this summer’s domestic blockbuster, Moon Man, earned 997 million yuan at the box office in the first three days of the weekend, with an obvious gap between the two. Moon Man finally got a box office of 3.1 billion yuan. As of December 23rd, Cat’s Eye predicted that Avatar 2 would finally get a box office of 1.003 billion yuan.

Jurassic World 3 was released in China on June 10th this year, with a box office of 355 million yuan in the first weekend and 495 million yuan as of June 17th (the eighth day of release), which were not as good as Avatar 2′ s box office in the same period, but it finally got 1.059 billion yuan in the mainland.

The reason why Avatar 2′ s box office was not as good as expected in the first week of its release in mainland China was mainly affected by the epidemic situation, which can be seen from the rare high refund rate in the first three days of its release in mainland China.

According to the cat’s eye data, the refund rates of Avatar 2 at the screening on December 14th and the zero-point screening on December 15th are all around 20%, and the refund rates in the first three days of release are 14.8%, 12.7% and 10.8% respectively, which is much higher than the industry average of about 5%.

This extremely rare high refund rate fully shows the strong impact of the epidemic on the box office of Avatar 2 on the first weekend. Its release is far below the expected attendance rate of the market, and the impact of the epidemic can not be ignored.

Fortunately, these days, with the first batch of "Yangkang" in China returning to normal work and life, the number of people watching movies is increasing. It is expected that the box office of Avatar 2 in China will grow steadily, and the ticket price is also expected to fall.

Perhaps because of this, as of the morning of December 24th, the box office forecast of Avatar 2 in Cat’s Eye Professional Edition has quietly risen to 1.062 billion yuan.

The biggest attraction of Avatar 2 is, of course, the stunning and extraordinary 3D visual effect, which is the surprise that director Cameron brought to the global audience through Avatar 13 years ago and the consensus established from it.

From this point of view, Avatar 2 will never disappoint! After "Yangkang", this week, I went to the Dolby Cinema Hall of Wanda Studios wanda plaza Store in Tongzhou, Beijing to watch this 193-minute super blockbuster, and enjoyed this unparalleled audio-visual feast in an immersive way.

The blue and deep underwater world, Tukun and other magical marine life are incredibly realistic. An island reef like a paradise, and a beauty on an island reef that looks like a water snake. The magnificent picture that has never been seen before is refreshing …

The epidemic has been going on for three years, and I have never heard of any case of infection in the cinema. For this reason, audiences in Beijing and other places do not need to check the 48-hour nucleic acid negative certificate when they go to the cinema to watch movies.

On the eve of the release of Avatar 2, director Cameron said confidently that the special effects of Na Mei Ren’s moving capture and expression capture were much better than those of Marvel Comics’s Thanos, and promised that the special effects of Avatar 2 were true. This statement is true.

IMDB has been kept above 8 points, rotten tomatoes above 80%, and popcorn index as high as 94%. Douban scored 8.5 points and currently stands at 8.1 points. Both Cat’s Eye and Taobao Film scored 9.2.

The famous film critic Electronic Knight commented: "Although there are some flaws in the plot and characters, which are not as neat and seamless as the first one, there is still no problem in killing almost all commercial blockbusters in the last decade (except two or three films such as Interstellar, the Dark Knight)."

Xieirs, a user of Douban, thinks Avatar 2: "Hanging all Marvel Comics films and 95% Hollywood commercial films in the past decade. The effect of underwater virtual shooting is epoch-making, and the light and shadow are unparalleled. There is something wrong with the script, but it looks good … "

It is no exaggeration to say that Avatar 2 is a movie made for cinemas, and it is only suitable for viewing in cinemas, especially in special cinemas such as IMAX, CINITY, Dolby Cinema, PRIME, LUXE and China Giant Screen, and of course it is also suitable for viewing in ordinary 3D cinemas with good cinemas.

In the first week of the release of Avatar 2, the market share of Wanda Cinema increased significantly. This is not only because its studios have many special cinemas, but also because of the high brightness and good quality of its ordinary 3D cinemas.

Traditionally, the Chinese New Year movie will be dominated by domestic blockbusters, and the key of imported films is generally only one month. Avatar 2 has a great chance of being shown on the eve of the Spring Festival. For those who want to watch this top-notch visual blockbuster in the cinema, don’t miss the remaining 20 days.

"Houses in the whole region can operate at an annual rate of 3.2%" and "after the holiday, the interest rate on loans is as low as 2.9%". After the interest rate cut on existing mortgages, some loan intermediaries "renovated" their routines on social platforms and continued to attract customers with low-interest gimmicks.

Zhuoling (pseudonym), the owner of a new site in a town in Dongguan, Guangdong Province, has recently received similar "lending" business calls. He told reporters that most of these calls claimed to be the channel manager of a bank at the beginning, introducing "internal" or "year-end welfare" loan products, saying that these products have internal approval channels and can also be used to help mortgage loans cut interest rates again.

But in fact, these loan intermediaries are not related to banks, but induce consumers to carry out a series of illegal operations under the layers of internal approval, high and low interest. Recently, banks in Henan, Hubei, Guizhou and other places issued statements to remind consumers of the risks of loan intermediaries, and denied cooperation with intermediaries in loan business.

"Renovation" Routine of Lending Intermediary

Recently, the First Financial Reporter contacted a number of loan intermediaries in Guangdong on the grounds of consulting business, and found that behind the "lending and interest rate reduction" business provided by some intermediaries, mortgage loans were actually converted into business loans, that is, consumers were guided to use bridge funds to settle their mortgages, and then their houses were mortgaged to banks in the name of corporate legal persons and shareholders, and business loans were lent to banks.

These institutions take "loan interest rate reduction" as the main gimmick to attract customers. In an interview in March this year, the above-mentioned loan intermediaries advertised that the annualized interest rate of operating loans after lending was mostly between 3.4% and 3.8%, but in recent interviews, they claimed that the annualized interest rate of operating loans could be applied for below 3%.

"Recently, the market as a whole has cut interest rates, and the operating loan interest rate has been further lowered, which is a good opportunity for lending." An intermediary of a lending institution in Guangzhou told reporters that if the mortgage is 2.3 million yuan and the annualized interest rate is 4.5%, it can be adjusted to 2.9% after the interest rate cut, and it can save 33,000 yuan a year, which can save nearly 900,000 yuan in interest.

She introduced that at present, her institution can contact the bank to plan two types of business loans: 10-year interest first, then principal, and 20-year equal repayment, with interest rates of 2.9%. However, after specific consultation, the reporter found that even if the series of conditions are met, the real interest rate is between 3.1% and 3.3%.

In addition to low interest rates as a gimmick, some loan intermediaries also took advantage of the opportunity to lower the interest rate of existing mortgage loans, trying to mislead customers by packaging the official identity of banks and confusing concepts.

One of them, Yue Qiu (a pseudonym), a loan intermediary who claimed to be the channel loan staff of the state-owned bank, told reporters that they had "internal relations" in the bank and could lower the mortgage interest rate on the current basis. At the same time, there will be a special person to follow up, which can help customers speed up the approval of bank loan applications and follow up the prepayment process when handling the related business of "lending and interest rate reduction", thus controlling the cost of bridge-crossing funds.

"We have banking channels. After you submit an application for prepayment, we can help you to expedite it." According to him, they will also confirm the operating loan amount that can be applied for in the new bank through the information of the real estate license. If customers need it, they can also help to raise the price of real estate assessment for "over-lending", and besides covering the amount of repayment in advance, they can also make some extra funds.

The reporter verified the above statement with the financial manager of a branch of a state-owned bank in South China. The financial manager said that the bank’s prepayment and lending processes usually have specific approval links, so it is difficult to directly interfere. Many promises of these loan intermediaries are basically "fudge". Most of them are only familiar with the operation procedures and loan policies of banks, and use this to guide consumers to conduct illegal operations, and the ultimate risk will still be borne by consumers.

There are many risks.

Why are some loan intermediaries still recommending the "lending" business after the interest rate cut of existing mortgage loans? Many insiders believe that it is mainly related to the existing spread space.

The above-mentioned Guangzhou loan intermediary said that although some customers stopped lending plans after the interest rate reduction of existing mortgage loans, the operating loan interest rate has also been declining recently, and the preferential strength is strong, and there is still a spread between the interest rate and the lowered mortgage interest rate.

Lou Feipeng, a research institute of China Postal Savings Bank, said that most residential mortgage loans in China are long-term loans, and the interest rate is based on 5-year LPR (loan market quoted rate), while operating loans are mainly short-term loans, and the interest rate is based on 1-year LPR. The five-year LPR is higher than the one-year LPR. At the same time, for the purpose of supporting the development of small and micro enterprises, the interest rates of operating loans and consumer loans are lower, further expanding the arbitrage space.

However, it is worth noting that behind the seemingly "arbitrage", there are many hidden costs and risks hidden in the lending business.

Zhuo Ling told reporters that when communicating with a number of intermediaries until the signing of the contract, he found that the actual interest rate reduction was not as cost-effective as expected, and there were many extra costs. On the one hand, the cost comes from "crossing the bridge" funds. According to the process, consumers need to use the bridge funds provided by the intermediary to settle the mortgage, and then go to the bank to apply for operating loans and return the bridge funds.

However, because the loan period is usually more than a week, or even as long as several months, the capital cost of crossing the bridge is not low. According to Zhuo Ling, at present, the daily interest rate of intermediary funds in the market is usually around "five thousand" (that is, five ten thousandths), which means that if you want to replace a 2.3 million yuan mortgage, you need to pay 1,150 yuan interest every day, and the interest for one month may be as high as 30,000 to 40,000 yuan.

On the other hand, these institutions usually charge a high service fee. The reporter contacted a number of intermediaries and found that the service fee is basically more than one point. For example, for a lending order of 1 million yuan, the service fee is at least about 10,000 yuan. In the process of borrowing business loans, if there is no business owner qualification or does not meet the corresponding requirements, "packaging" will require additional fees.

In addition to the high cost, the loan term is shorter after "lending", and the monthly supply pressure may increase instead of decreasing. A Dongguan owner who handled the re-lending business last year told the reporter that he changed the mortgage with an interest rate of 5.8% to a business loan of 3.8% at that time. The original loan was 3 million yuan, and the repayment was made by the equal principal and interest method for 30 years, with a monthly payment of more than 17,000 yuan. After being converted into a 10-year operating loan, it will pay back about 30,000 yuan per month. At the same time, it is also necessary to bear the risk of "lending". Once the bank examines that funds flow into the housing market illegally, it is necessary to fill the loan gap in a short period of time.

"The operation of lending to reduce interest rates is meaningless and risky." Yan Yuejin, research director of Yiju Research Institute, told the First Financial Reporter that such operations of transforming traditional mortgage business into business loans will "package" buyers as business owners. However, there are several problems. First, this kind of "packaging" also requires costs. Second, the operating loan period (mostly) is only 1-10 years, so the pressure of monthly loan repayment actually increases. Third, the post-loan inspection of banks will be stricter.

Regulators and banks have repeatedly warned.

Recently, banks in Henan, Hubei, Guizhou and other places have issued statements to remind consumers of the hidden risks in "lending to reduce interest rates" and handling loans, and at the same time stressed that bank loans have not cooperated with intermediaries.

For example, on October 7th, China Bank Guizhou Branch issued a notice in Guanwei, saying that illegal loan intermediaries would pretend to be "xx Bank" and "xx Bank Loan Center" to publish loan advertising information, or push the loan amount to consumers, claiming that "they have connections within the bank" and "they can apply for loans through internal processes" to trick consumers into handling loans through them. In fact, such intermediaries have nothing to do with banks, but only to trick borrowers into making false propaganda.

Dancheng Rural Credit Cooperative said in the announcement on October 7 that it has never cooperated with any intermediary agency or individual in loan intermediary business, nor has it authorized any third-party company or platform to carry out loan business; In the process of handling the loan business, no fees such as agency fee, service fee and mortgage registration fee are charged, except as stipulated in the contract.

In addition to banks, regulators have recently issued risk warnings. Ningxia Supervision Bureau of the State Financial Supervision and Administration Bureau issued a risk warning on preventing illegal loan intermediaries from infringing on the legitimate rights and interests of financial consumers in early October, which reminded consumers to enhance their awareness of risk prevention, be wary of unfamiliar phone calls or text messages to promote loan business in the name of "low interest and quick" and "approved loan amount", and do not provide sensitive personal information to others at will or authorize others to handle financial business at will.

As early as the end of 2022 and the beginning of 2023, the supervision focused on a round of rectification of loan intermediaries. At the end of 2022, the former China Banking and Insurance Regulatory Commission issued a risk warning that some unscrupulous intermediaries explored "business opportunities" and introduced mortgage loans to consumers. This operation of replacing mortgage with business loan hides risks such as illegal breach of contract, high charge trap, influence on personal credit information, capital chain break and infringement on information security. On February 2 this year, Shenzhen Real Estate Agency Association issued the "Solemn Reminder on Prohibiting Real Estate Agencies and Employees in the City from Participating in the Illegal Use of" Business Loans "; On February 13th, Liaoning Banking Insurance Regulatory Bureau issued "Risk Tips on Early Repayment of Loans or Lending", giving tips on the risks of operating loans and the norms of intermediary institutions.

Yan Yuejin believes that this kind of loan business is illegal in itself, and all localities still need to strengthen publicity, especially to strengthen the inspection of enterprise operation, to prevent all kinds of shell companies from taking such loan funds, and at the same time to increase control over intermediaries.

In 2017, Huawei seems to have a bad year. This Fortune 500 company, which has always enjoyed a high reputation among Chinese people, has been criticized by the public more than once, whether it is the rumored layoff plan for employees over 34 years old or Huawei P10, which has been caught in various negative rumors recently.

If the layoff plan for 34-year-old employees is not empirical and is an accident, then the problem of Huawei P10 is self-inflicted, and in the process of continuous fermentation, some untimely and arrogant remarks made by Huawei consumer BG CEO and chairman of Huawei Terminal Company Yu Chengdong have made the problem more and more serious.

The news about Huawei’s "flash door" is no stranger to everyone. The origin of the news is that some users found that Huawei used three different flash memories on P10, namely UFS2.1, UFS2.0 and EMMC5.1. In the previously released Huawei Mate 9, Huawei once used UFS2.1 as a selling point, which made those users who bought EMMC5.1 flash memories extremely dissatisfied. Not only is it a "flash door", before that, Huawei P10 was greatly annoyed by the lack of oleophobic layer, and this time, the "flash door" is even more like adding fuel to the fire.

Since then, in response to these incidents, Yu Chengdong’s arrogant attitude and so-called "a lot of speculation by friends and businessmen" have not only failed to calm public opinion and explain the problem clearly, but have unexpectedly contributed to the uncontrollable development of the incident.

As for why Yu Chengdong’s remarks have become an accelerant for the increasingly serious incident, we have to say that there is an unwritten rule in the circle of technology products.

In this industry, it seems that the boss of every manufacturer has his own "personal design" corresponding to his own products. To outsiders, this "personal design" of the boss can almost be equated with their products.

For example, Apple and Jobs, who have been mythologized, are both representatives of perfectionism. Lei Jun and his Xiaomi strive to present an engineer temperament to their users; Lao Luo and hammer, with the word "feelings" to fight the world; Yu Chengdong, relying on Huawei’s rapid sales and brand promotion in the past two years, has made amazing remarks frequently and got the nickname of "Yu Dazui".

Yu Chengdong’s outspokenness is actually a rare quality in this industry, especially those brave words about the future development prospects of Huawei’s mobile phones, which always make people believe in him.

However, if you talk too much, you will inevitably make mistakes, especially when Huawei is negatively involved.

Seeing that things still showed no signs of calming down, Yu Chengdong spoke again. Compared with the tough and arrogant attitude before, Mr. Yu seems to have bowed his head this time, seemingly apologizing, but he still adopts the names of "internal letter" and "proposal", and has not given a solution to "flash door" from beginning to end, showing a reluctance and a peace of mind.

Looking at the whole Proposal, we can see what we want in the future everywhere. Without mentioning a word about what happened before, we stated that we would set up a "consumer listening special action group", and during May Day, Yu Chengdong would personally lead a team to retail stores, service shops and stations to communicate with consumers at close range.

But what’s the point of such a "consumer listening task force" if you can’t even listen to the problems that have been raging on the Internet? Such an initiative can only be understood as "I know I’m wrong, but I’m not going to correct it, and I’m wrong if I was wrong before, and there’s nothing you can do about it."

Such a "proposal" is really not as good as none.

Since this proposal was issued, many people have classified it as a "stupid public relations" series, and the criticism against it is still endless. If there is no accident, Huawei may continue to make more responses.

However, can consumers wait for a real apology and a solution to the problem? Who can make Huawei and Yu Chengdong lower their heads?

In fact, the life of Huawei’s consumer business is not easy at present. As the CEO of consumer business, Yu Chengdong is under great pressure.

According to the 2016 annual report data released by Huawei, the most concerned consumer business achieved sales revenue of RMB 179.8 billion in 2016, up 43.6% year-on-year, and the annual smartphone shipments reached 139 million units, up 29% year-on-year. Compared with OPPO and vivo, which are chasing after each other, this kind of data is hard to say bright, and it also fails to meet Huawei’s own expectations.

At the same time, in 2016, Huawei’s net profit was 37.1 billion yuan, a year-on-year increase of only 0.4%. Therefore, on the one hand, the development of Huawei’s smart phone business encountered a bottleneck in the past year; on the other hand, "the profitability is still insufficient and the profit growth is too slow" became Ren Zhengfei’s biggest accusation against Yu Chengdong.

But even so, it cannot be the reason why Huawei is so arrogant to consumers, and such arrogance is likely to kill a domestic backbone brand that has been booming.

I think anyone who pays a little attention to the smart phone industry knows that Huawei’s goal is not only in the domestic market. Before, there was a slogan of "surpassing Apple in three years and surpassing Samsung in five years", but we know that this is a company with global ambitions. If you want to become a world-famous brand, you must have enough brand premium, and these brand premiums come not only from the product itself, but also from the recognition of consumers and the honest management of the enterprise itself.

However, like Huawei, frequent crises caused by consumers’ dissatisfaction with product quality are undoubtedly the most serious loss to the brand. Lessons from the past, such as Samsung Note 7, have been fully recalled, and Samsung S8 has also appeared, but until now, Samsung still can’t completely put aside the shadow of the battery explosion, and it can be expected that this topic will be a sore point for Samsung in the next year or two or even longer, and it will be repeatedly mentioned by users.

There is a well-known Tacitus trap in sociology, which means that when a government department or an organization loses its credibility, no matter telling the truth or lying, doing good or bad things, it will be considered as telling lies or doing bad things. The same is true for the brand building of enterprises. It is not easy to build a brand, but it is easy to destroy a brand. When the brand was destroyed, it was even more difficult to make a comeback.

At present, the negative effects caused by Huawei P10 are far from as serious as those caused by Samsung Note 7 at that time. However, looking back at history, those problems that were considered as major events were often ignored at the beginning, and it was not until they were finally irretrievable that they regretted not being able to contain the problems in the bud at the beginning.

The problems that Huawei is facing now may be such a bud. It is not too difficult to apologize and admit mistakes and provide some practical and reliable solutions. But why Huawei is unwilling to do so and bet on its own brand reputation is incomprehensible.

Is it really impossible for Huawei and Yu Chengdong to keep their heads down? Stubbornness and stubbornness are not the way to solve the problem. Don’t let Yu Chengdong destroy Huawei, a brand with unlimited possibilities.

　　Waterlogging disaster

　　Because the rainstorm is urgent and heavy, poor drainage can easily lead to waterlogging, and the soil pores are filled with water, which causes the root system of terrestrial plants to lack oxygen, inhibits the physiological activities of the root system, and causes crops to suffer and reduce production.

　　In cities and towns, when too much rain exceeds the drainage capacity, water will flow on the road surface, and stagnant water will form in low-lying places, resulting in urban waterlogging, which has a great impact on transportation, industrial production, commercial activities and citizens’ daily life.

　　flood damage

　　Flooding caused by rainstorm inundates crops, making it difficult for crops to metabolize normally and causing various injuries. The deeper the flooding, the longer the flooding time, and the more serious the harm to agriculture, forestry and fisheries.

　　Heavy rain causes rivers to flood, and also causes geological disasters such as flash floods, landslides and mudslides, which not only harms crops, but also destroys farmhouses, industrial and agricultural facilities and roads, and even causes human and animal casualties and serious economic losses.

　　Almost all the floods in the history of our country were caused by heavy rain, such as the flood in the Yangtze River basin in July 1954, the flood in Hebei in August 1963, the flood in Henan in August 1975, the flood in Jianghuai in 1991 and the catastrophic flood in the whole Yangtze River basin in 1998, which all caused serious economic losses.

　　On June 5-6, General Secretary of the Supreme Leader visited Bayannaoer, Inner Mongolia, and presided over a forum. The theme of the meeting is to strengthen the comprehensive prevention and control of desertification and promote the construction of key ecological projects such as "Three North".

　　"We must adhere to the concept of system, solidly promote the integrated protection and systematic management of mountains, rivers, fields, lakes, grass and sand", "We must highlight the key points of management and do our best to fight three landmark battles" … … Starting from the concept of system, the General Secretary of the Supreme Leader made comprehensive arrangements for fighting the "Three North" project.

　　"Insisting on the concept of system" is the epistemology and methodology of combating desertification in the new era, and it is also one of the standpoints and methods that run through the Supreme Leader’s Socialism with Chinese characteristics Thought in the new era.

　　a community of life

　　On the morning of the 6th, General Secretary of the Supreme Leader came to the state-owned Xinhua Forest Farm in Linhe District, Bayannur, Inner Mongolia to learn about the construction of the "Three North" shelter forest system.

　　"Mountains and rivers, forests, fields, lakes, grass and sand", ecology is a unified natural system and an interdependent and closely related organic chain. In the mind of the Supreme Leader General Secretary, "the lifeblood of man lies in the field, the lifeblood of field lies in water, the lifeblood of water lies in mountains, the lifeblood of mountains lies in soil, and the lifeblood of soil lies in forests and grasses. This life community is the material basis for human survival and development".

　　The important exposition of "life community" embodies the scientific method of systematic thinking.

　　In November 2013, General Secretary of the Supreme Leader pointed out that the landscape, forest and lake are a community of life. Later, he added "grass" and "sand" to it.

　　From "landscape forest field and lake" to "landscape forest field and lake grass and sand", the increase in the number of words reflects the process of deepening the understanding of system governance and enriching the connotation.

　　Adhere to the integrated protection and systematic management of mountains, rivers, fields, lakes, grass and sand. The General Secretary stressed at this symposium that "it is necessary to coordinate the ecological protection and restoration of forests, grasslands, wetlands and deserts, strengthen the coordination and management of all elements of sand control, water control and mountain management, and strive to cultivate healthy, stable and fully functional forest, grassland, wetland and desert ecosystems".

　　"Community of Life" means that mountains, rivers, forests, fields, lakes, grass and sand are inseparable ecosystems. "Use control and ecological restoration must follow the laws of nature. If trees are planted only, water is controlled only, and fields are protected only, it is easy to take care of one thing and lose sight of another, which will eventually lead to systematic ecological damage."

　　The general secretary requested that "all elements of natural ecology should be considered as a whole according to the inherent laws of the ecosystem, so as to achieve the goal of enhancing the recycling capacity of the ecosystem and maintaining the ecological balance".

　　The general secretary also reminded that it is necessary to calculate big accounts, long-term accounts, overall accounts and comprehensive accounts. If we lose too much because of small things, we will eventually cause systematic and long-term damage to the ecological environment.

　　National "chess game"

　　The "Three North" project, starting from Xinjiang in the west and Heilongjiang in the east, is a green Great Wall stretching across Wan Li.

　　"Build the green barrier of Wan Li in the northern part of the motherland more firmly", and the "Three North" project plays an important role in the national "chess game" of ecological civilization construction.

　　Fighting a tough battle for the "Three North" project, the Supreme Leader General Secretary stressed at this symposium that "it is necessary to strengthen regional joint defense and governance and break administrative boundaries".

　　He who does not seek the overall situation does not seek a domain. The management of the two mother rivers also runs through the systematic concept of "one chess game" in the whole country.

　　On September 18, 2019, at the symposium on ecological protection and high-quality development in the Yellow River Basin, the General Secretary warned the leading comrades present, "The development along the Yellow River must have a sense of the overall situation, consider it from a national and overall perspective, and firmly establish ‘ A game of chess ’ Thought. "

　　On November 14, 2020, at the symposium on comprehensively promoting the development of the Yangtze River Economic Belt, the General Secretary stressed the need to "promote the interaction and cooperation between the upper, middle and lower reaches and enhance the relevance and coupling of various initiatives".

　　Looking at the system from a holistic perspective and a collaborative perspective provides a scientific thinking method for forward-looking thinking, overall planning and overall promotion of China’s ecological civilization construction.

　　"To seek a new way of governance from the perspective of systems engineering and the overall situation, we can no longer treat the headache and the foot pain, and each tube is tied to each other." On May 18, 2018, the General Secretary pointed out at the National Ecological Environmental Protection Conference.

　　Highlight the key points of governance

　　Wuliangsuhai, located at the top of the "Zigzag Bend" of the Yellow River, is the intersection of multiple ecological functions in northern China and a natural ecological barrier to control the sandstorm source in Beijing and Tianjin. On the afternoon of the 5th, General Secretary of the Supreme Leader came here to inspect, and he emphasized that managing the Wuliangsuhai River Basin well is of great significance for ensuring the ecological security in northern China.

　　The general secretary attaches great importance to the management of Wuliangsuhai River Basin. During the two sessions of the National People’s Congress in 2021, when the General Secretary participated in the deliberation of the Inner Mongolia delegation, he pointed out that "I have given many instructions to Wuliangsuhai". On this inspection site, the General Secretary also called for "careful management, careful care, consistent and long-term efforts to protect this ‘ Pearl beyond the Great Wall ’ " .

　　It is also the proper meaning of the system concept to highlight the key points, drive the overall situation and grasp the relationship between the main contradiction and the secondary contradiction.

　　For example, to fight a tough battle against pollution, the general secretary stressed that "we must fight several landmark major battles and concentrate our efforts on overcoming the outstanding ecological and environmental problems around the people."

　　When it comes to combating desertification, the General Secretary stressed at this symposium that "we should highlight the key points of governance and do our best to fight the three landmark battles".

　　We will do our best to fight the "zigzag" battle of the Yellow River, fight the annihilation battles of Horqin and Hunshandake, and fight the Hexi Corridor — Blockade on the edge of Taklimakan Desert. In every landmark battle, the general secretary clearly indicates the direction and draws the key points.

　　Adhering to the concept of system, grasping the relationship between the overall situation and local, current and long-term, macro and micro, principal contradiction and secondary contradiction, special and general, has led to a broad and profound systematic change in China’s ecological civilization construction.

　　Constantly improve the political "three forces" and accelerate the construction of a new development pattern

　　— — In-depth study of the important speech of the Supreme Leader General Secretary at the provincial and ministerial seminars (Part III)

　　At the opening ceremony of the seminar for leading cadres at the provincial and ministerial levels at the Central Party School (National School of Administration) to study and implement the spirit of the Fifth Plenary Session of the 19th CPC Central Committee, the General Secretary of the Supreme Leader pointed out: "Leading cadres at all levels, especially senior cadres, must be based on the overall situation of the great rejuvenation strategy of the Chinese nation and the unprecedented changes in the world in the past century, with a heart ‘ The great man of the country ’ Constantly improve political judgment, political understanding and political execution, constantly improve political ability, strategic vision and professional level in grasping the new development stage, implementing the new development concept and building a new development pattern, dare to take responsibility and be good at doing things, and implement the decision-making arrangements of the CPC Central Committee. " In the face of profound changes in the world situation and national conditions, the important speech of the General Secretary focuses on understanding the law, grasping the principles, and clarifying the path, which is of great and far-reaching guiding significance for us to unify our thinking, improve our position, broaden our horizons, and further implement the decision-making and deployment of the CPC Central Committee.

　　As a Marxist political party, stressing politics is a fine tradition of our party and a fundamental requirement. From Nanhu Red Boat to Jinggang Xiufeng, from Zunyi Ancient City to Yan ‘an Pagoda, the Communist Party of China (CPC) people have all demonstrated the high political consciousness of Marxist political parties in a series of struggles, developments and practices, and turned their political advantages into inexhaustible power to overcome all the risk challenges on the road ahead and constantly move from victory to new victory. Now, the cause of the Party and the country has reached a new historical position and development stage. Only when Do not forget your initiative mind keeps his mission in mind, systematically studies and thoroughly understands the exposition of the Supreme Leader General Secretary on why to talk about politics, what kind of politics to talk about and how to talk about politics, and constantly improves his own political judgment, political understanding and political execution, can he unite as one, go all out and persevere in achieving the set goals.

　　Good governance, good things. The world today is experiencing a great change that has never happened in a century. We have also made timely adjustments to our development concepts and ideas. The new development pattern has become a major strategic task and needs to be accurately grasped and actively promoted from the overall situation. Whether we can better improve our political stance, strengthen our political stance and strengthen our political responsibility will determine the quality and level of our final answer to the topic of the times. In fact, talking about politics is not only a kind of attitude and position, consciousness and direction, but also a manifestation of ability and accomplishment. Political judgment, political understanding and political execution are about the materialization and refinement of politics at the practical level. Political judgment means that when facing problems, we should have the ability to scientifically grasp the changes of the situation, accurately identify the essence of the phenomenon, clearly distinguish between right and wrong behaviors, and effectively resist risk challenges; Political understanding is to always maintain a high degree of consistency with the CPC Central Committee in work, be clear about the "big country", and define your own responsibilities; Political executive power means that we must always benchmark ourselves against the spirit of the CPC Central Committee and carry out the spirit of the CPC Central Committee to the letter.

　　Correct stand and scientific practice are the important support to achieve practical results and realistic results. In the past year, under the strong leadership of the CPC Central Committee with the Supreme Leader as the core, people of all ethnic groups throughout the country fought bravely and made great strategic achievements in the fight against the COVID-19 epidemic. At the same time, they took the lead in resuming work and production, realizing economic growth from negative to positive, becoming the only major economy in the world to achieve positive economic growth, and handing over an excellent answer that was satisfactory to the people, attracted worldwide attention and could go down in history. It can be said that without the Communist Party of China (CPC) people always keeping the people in mind and taking loyalty to the party, sharing worries for the party and doing their duty for the party as the yardstick in their hearts, generate would not have been able to cultivate new opportunities in the crisis and open up new opportunities in the changing situation.

　　Our party is about to celebrate its centenary birthday. In accordance with the requirements of the Supreme Leader General Secretary, we should further strengthen the "four consciousnesses", strengthen the "four self-confidences" and achieve the "two maintenances", turn our political advantage into a driving force, and forge ahead courageously in the direction of continuing to deepen the supply-side structural reform, comprehensively optimizing and upgrading the industrial structure, paving the way for building a new development pattern, and ensuring that the major decision-making arrangements of the CPC Central Committee on development during the 14 th Five-Year Plan period are implemented.
