Film Review Hunger 3: The long happy ending is finally over!


1905 movie network news This film completely announced the end of this series to the public. At the end of the film, the eldest cousin jennifer lawrence not only lived sweetly with Pita, but also gave birth to two lovely babies, and happily began to recall the past as a mother. Obviously, the series wants to say goodbye to the fans who have supported them for several years with a happy ending, but unfortunately, no matter how much the last film has feelings of farewell and departure, it can’t cover up the old problems that the series is dragging on, lengthy and moaning.

 

The Hunger Games is a series of film works. From the beginning of the first film, the story progress of each episode is not too much, and there are a lot of story foreshadowing and antecedents. If this operation method is understandable at the beginning of the series, then the verbosity and procrastination of the second episode of single spark can start a prairie fire is not so acceptable. But what’s even more ridiculous is that the third part of the original novel is stiffly split into two episodes and shown separately. The naked money-circling behavior is unforgivable, and the boredom and boredom make this behavior look even more shameless. Therefore, many people’s expectations for The Hunger Games 3: Mockingbirds (Part 2) are ironic, just because it can finally be seen to be over.

 

Because the struggle between good and evil in the whole story has to be solved perfectly in the final chapter, there are bound to be a lot of scenes of revenge and fighting, which makes the story of Hunger Games 3: Mockingbird (Part 2) look less boring as a whole. Occasionally, a few small climaxes are not bad, no matter in rhythm control or visual creation, at least many viewers are nervous, and in these bridges, the character of the big cousin is fully shaped. But in fact, the excitement of The Hunger Games 3: Mockingbirds (Part 2) is limited to these fragmentary places. Even the reversal of the plot at the end of the film is not surprising to the audience. After all, while portraying a villain Si Nuo, the film reveals Julian Moore’s villain characteristics too obviously, paving the way for so much, and no one can see the director’s little career.

 

This love of bedding has not changed at all in The Hunger Games 3: Mockingbird (Part 2). The film length of more than 130 minutes, the last hour, is probably a story, an ambush pen, and even the final confrontation between opposing forces, that is, a simple explosion. It is also rare that the plot turns sharply and awkwardly. Even the most off-screen couple in history, Big Cousin and Pita, their relationship has been ambiguous, and the two kisses of Big Cousin have caused two bursts of laughter in the cinema. It is really difficult for Big Cousin, who walks between two men in the whole film, to make her make a choice. Of course, this ambiguity finally went to the right direction in the second half of the story. Kate Nice finally chose to trust Pita, but Pita, who didn’t have any eggs in the film, finally overcame her demons and finally walked with her at the end of the film. What the director wants to highlight is the true affection between two "game players" who have been born and died, but in the long entanglement, this feeling seems so weak.

 

The main scene of The Hunger Games 3: The Mockingbird (Part 2) has always focused on Kate Nice. For this screen myth with youth, beauty and rebellious spirit, the film really wants to put too much on her. From an ordinary girl to a generation of spiritual leaders, her path is tortuous and difficult. Faced with the death and injury of innocent people, the death of relatives, the departure of friends, the pain of beloved, etc., Kate Nice resolutely embarked on a road of no turning back in the name of revenge. Heroism in Hollywood is really an eternal topic. The film creates a heroic atmosphere with all kinds of ceremonial details, while Kate Nice has become the embodiment of freedom and justice because of the current situation, wearing a tight black leather coat and a black domineering longbow, and the visual image of a female warrior jumps from the paper.

 

However, this heroic feeling obviously ignores the complexity of her as a woman and a person. In The Hunger Games 3: The Mockingbird (Part 2), no matter how many hardships and difficulties Kate Nice encounters, the film emphasizes her courage and persistence. Under the big close-up and the hard expression of her big cousin, this character is too thin. This thinness can not be achieved by giving her love, affection and other relations and problems.

 

Of course, The Hunger Games 3: The Mockingbird (Part 2) is not just a story about revenge and the struggle between good and evil. Just like the original, this series is all about a dystopian theme. The new world and people’s desires, all kinds of political metaphors and reflections are full of it. The director seems to have a huge ambition to build a new world with a unique cognitive system, but he has never escaped from the previous cage and commercial shackles. For the description of class, oppression and resistance, the general public is generally described as insensitive, leaving Kate Nice and some of her comrades-in-arms sober-headed, and the great difference in the portrayal of heroes and non-heroes is also one of the reasons why this film is more and more like a small game.

 

It is true that the Hunger Games series is a part of the popular youth movie series in Hollywood, and the heroine herself is quite popular in the United States because of her excellent acting skills and good personality, but no matter how lively, the Hunger Games series films are not particularly good works. Then, although the trilogy of the original novel has been filmed, the capitalists have not put their words to death, and it is not impossible for the sequel to prequel in the future.

Rare and Wrong Edition Collected by the Elderly: RMB Market Valuation in 50 yuan: 500,000 (Figure)

  Rare wrong edition! 50 yuan RMB Watermark Inversion


  After 15 years of collection by an old man in Lanzhou, this newspaper publicly displayed it for the first time. Experts said that its market valuation was 500,000 yuan.


  The old man Zhu Canxiang of Lanzhou has a distinctive RMB in his hand. This 1990 version of 50 yuan RMB looks normal, but after careful identification, it will be found that the watermark of Chairman Mao on the front of the RMB is upside down. After identification by many bank staff, it is indeed a genuine RMB, but it is also a rare wrong version of RMB.


  50 yuan RMB watermark is printed upside down.


  In the early morning of December 3rd, the old man Zhu Canxiang, who lives in Heping New Village, Lanzhou City, came to our newspaper and showed the reporter a RMB numbered GS8790902 with a face value of 50 yuan that he had treasured for 15 years.


  Although the 1990 version of RMB is rare in the market, it is not a rare thing to meet it. However, this piece of RMB in 50 yuan has kept Zhu Canxiang as a treasure for 15 years, and there must be something special about it. However, Zhu Canxiang, an old man, is not in a hurry to tell reporters the "mystery".


  After careful identification by the reporter, it was found that this 1990 edition of 50 yuan RMB numbered GS8790902, like other versions with the same face value, has the heads of workers, peasants and intellectuals on the front and the Hukou Waterfall of the Yellow River on the back, but the difference is that the head of Chairman Mao is inverted like a watermark, and its position is higher than that of normal coins. The watermark of this coin is so different from the normal coin. Is it a counterfeit coin? However, Zhu Canxiang told reporters that no matter which bank he checks this banknote, the same result will appear: it is a real coin.


  Verify that it is the wrong version of RMB.


  In order to confirm the authenticity of this coin, the reporter and Zhu Canxiang first came to the business hall of Gansu Branch of Industrial and Commercial Bank of China that morning. After shaking out of thin air and flicking the face, the bank staff repeatedly put the coin into the money detector for verification, and confirmed to us that this coin is genuine. Subsequently, the reporter and Zhu Canxiang came to China Construction Bank, China Merchants Bank, commercial banks and other banks to verify this banknote. The results are the same, and the money is real!


  In this regard, the bank staff told the reporter that this may be the wrong version of RMB. Since the coins have to go through seven strict checkpoints before leaving the factory, the probability of making mistakes is between one in a million and one in a million. Most of them are missing printing, white folding, corner folding, displacement, offset printing, dislocation, watermark inversion, watermark deviation, and so on. However, there are very few wrong version coins like this 50 yuan watermark inversion held by Zhu Canxiang.


  A wrong coin has been treasured for 15 years


  Where did this wrong coin come from? The old man Zhu Canxiang told reporters that this had to start from 1992.


  At that time, Zhu Canxiang was still working in the Red Star Carton Printing Factory in Lanzhou City. At that time, the salary was directly discovered by the unit. Zhu Canxiang was very careful at ordinary times. After paying his salary, Zhu Canxiang verified the authenticity of these coins one by one. As a result, it was found that the 50 yuan RMB watermark numbered GS8790902 was inverted, but the texture and blind spots were normal. It is really hard to say whether it is true or not. I wanted to take it to the bank for verification, but because 50 yuan was not a small number in those days, I was afraid that the bank would confiscate it if it verified that it was counterfeit. So I asked an acquaintance who works in a bank to verify it. As a result, the other party told him that it was real money. At that time, he was dubious, and he went to several banks to verify it, all of which were the same result: this is a real coin.


  The old man Zhu Canxiang said that since then, he has consulted relevant information and found that this is the so-called "wrong version of the coin", but because this kind of wrong version of the coin is rare, it is particularly precious. "Things are rare, and this kind of coin will definitely appreciate." Zhu Canxiang said that not long ago, he went to the Lanzhou ancient coin market and asked some collectors. The market price of the 1990 edition of 50 yuan’s watermark-inverted misprinted coins was estimated to be 500,000 yuan.


  Experts remind you to identify the wrong version and go to the bank.


  It is understood that in recent years, the collection value of RMB sets is getting higher and higher, but for many ordinary collectors, it is not easy to collect a whole set of brand-new RMB with excellent quality. Therefore, many collectors turn to collect wrong coins in order to obtain higher returns.


  At present, the price of the wrong edition coins sold in the market is more than 300 thousand yuan, and the price of the inverted watermark coins is more than 500 thousand yuan. In this regard, experts from the Provincial Collectors Association said that due to the extremely rigorous review procedures of RMB issuance, the probability of wrong coins is not high, and from experience, there are not many real wrong coins on the market.


  According to reports, the wrong coins that have appeared at present generally have watermark inversion, missing printing, white folding, corner folding and displacement. "Although it is normal that the wrong version of the currency is worth more than 100,000 yuan, it is not practical to price it too high. There are also a few lawless elements who use laser processing and other means to forge’ wrong coins’. " To this end, experts remind collectors that it is best to identify the wrong coins in a bank with professional identification standards to prevent being deceived.

  Some wrong versions of RMB in China


  In October 2002, Mr. Ma, who lives in Yinchuan Power Transmission and Transformation Family Hospital, accidentally got a 1990 version of RMB 100 with the number PL33902170. The watermark on it was inverted, but it passed the money detector and was identified as a wrong version of RMB.


  In October, 2007, Mr. Liu, a citizen of Guiyang, collected the wrong version of RMB issued in 100 yuan in 1980. Mr. Liu’s wrong version of the RMB number is CU20361732, and the watermark of Chairman Mao is inverted.


  In September, 2007, Ms. Li, a top student in Yantan, Lanzhou, received a blue 100-yuan RMB in 1990 when collecting money. The security line and watermark pattern of this RMB were upside down. After identification, it is the wrong version of RMB.


  In September 2007, Ms. Cheng from Liaoning received a 1990 version of 50 yuan money, and the pattern on the back shifted up and down, which was extremely uncoordinated. Coincidentally, her neighbor, Sister Liu, also received a coin with a layout value of 100 yuan in 1990, which left a "1" missing and became "00" yuan. After identification, they are all wrong versions of RMB.


  In July, 2007, Mr. Du from Xinxiang, Henan Province showed a wrong edition of RMB with the number XG48242185 in his collection. Watermarks overlapped under the anti-counterfeiting lamp and changed into "10,000" RMB notes. After identification, this 100 yuan RMB is genuine.

Netease cloud music version 5.0 is heavily launched, and the new video page is what you want to see.

Recently, Netease Cloud Music Version 5.0 was fully released on Android and iPhone, providing music users with the latest products and services. In this big version update, Netease Cloud Music not only upgraded the video page, but also expanded the application scope of personalized recommendation algorithm in products to meet the diverse music needs of users.

Brand-new video page, see what you want to see

In version 5.0, Netease Cloud Music added a video tab to the navigation bar, and launched a brand-new video page as the secondary page of the product. The video page set of previous MV and short video content has become an independent page in version 4.2, and in this version update, Netease Cloud Music has comprehensively upgraded the video page architecture.

The most obvious thing is that there are classified pages under the video page, which are divided into more than ten categories according to the video content, such as music, MV, pop music, cover, second element, music scene, playing and singing. Like video homepage recommendation, these classified pages generate personalized recommended video streams according to users’ preferences, and the content can be updated every time the page is refreshed, which is convenient for users to enjoy video content in different categories. In addition, the video page also adds a search function, through keyword search, you can quickly find the video you want to watch.

(Video page)

Since its launch, Netease Cloud Music has been adhering to the innovative product spirit, putting users first, constantly updating and improving products by analyzing user needs, and providing users with the ultimate music experience. And this 5.0 version update, the new video page on the line, also conforms to the needs of users.

      There are various forms of music presentation, and video is an important music carrier. Moreover, in the form of Live concert and live performance, video can show the power of music from two aspects: sound and picture, which is more stereoscopic and comprehensive. On the other hand, the introduction of video function also provides musicians with more ways to spread. The threshold of video recording is low. By releasing videos, musicians can not only show their works, attract attention, but also effectively enhance interaction. After song lists, comments, radio stations and columns, it has become a common mode of communication for many musicians, especially original musicians.

(Milk coffee often spreads music works by releasing videos.)

Therefore, in March 2017, the short video function was launched in Netease Cloud Music 4.0, and Netease Cloud Music became the earliest music APP with video function. After the video function was launched, according to the background data of Netease Cloud Music, the user’s stay time on the video page and the video playback rate have been improved several times, which reflects the user’s love for video content. And original musicians such as Milk Coffee and Xie Chunhua often post videos on musicians’ homepages to actively communicate with users. With the upgrade of the video page in version 5.0, the video function has further played the role of "music socialization", closely connecting musicians and users, and has become an important way to announce original music. 

The application scope of personalized recommendation algorithm is expanded.

     Netease Cloud Music’s personalized recommendation algorithm has always been known for its accuracy, and its personalized recommendation function has been widely used in many functions of products, and even called by many users as "knowing yourself better than a man/girlfriend". In the 5.0 version, Netease Cloud Music added a theme keyword content recommendation module and a "guess what you like" module, both of which introduced personalized recommendation algorithms.

(Subject Keyword Content Recommendation Module)

The theme keyword content recommendation module mainly recommends the content of the same theme according to the user’s music preference. Music categories as big as ancient style and secondary element, as small as singers or musicians such as Jay Chou, may become the theme of recommended content. The "guess what you like" module mixes a variety of music preferences of users, and then appears in this module through algorithm recommendation. For example, a person who likes both folk songs and European and American music may see the contents related to folk songs and European and American music in the "Guess what you like" module.

("Guess what you like" module)

In addition, the new video page of Netease Cloud Music also introduces personalized recommendation algorithm. The expansion of the application scope of personalized recommendation algorithm in Netease Cloud Music means that the whole product will be more personalized for users, and the recommendation of music content by thousands of people will make it more convenient to discover and share favorite music. For musicians, it can make music works heard by more potential users, and then promote the creation of original works.

(Add "Don’t miss the wonderful" module at the top of the friends page)

       In the latest version, Netease Cloud Music will also upgrade the sign-in page to a music sign, and you can get beautiful pictures, songs or music reviews every day when you sign in. In addition, at the top of the friends page, Netease Cloud Music has added a "Don’t miss the wonderful" module. From now on, you are no longer afraid to miss the dynamic updates of friends you care about.

In high acid environment, this kind of bacteria is still "alive and kicking". How to treat it?

Original Hu Yang Changxiao Healthy

▼ The author of this article ▼

Recently, a friend recommended a toothpaste to me, saying that it can inhibit and prevent Helicobacter pylori. The price is slightly more expensive than ordinary toothpaste, so I bought a little with a try. In fact, I also know that it is unrealistic to prevent or treat Helicobacter pylori by toothpaste.

The human stomach is an acidic environment with a PH value of 0.9-3. In such a high-acid environment, there will be a kind of bacteria alive and kicking in it. This kind of bacteria is Helicobacter pylori, which belongs to a kind of micro-aerobic gram-negative bacteria. The infection rate of Helicobacter pylori in the global natural population exceeds 50%, and the detection rate of Helicobacter pylori in the stomach is 30%-80% in different ethnic groups in different regions of China.

Helicobacter pylori can destroy the mucous layer in the stomach, expose the gastric mucosa to gastric acid and be damaged by gastric acid. Helicobacter pylori will also release some toxins and enzymes to damage gastric mucosal epithelial cells and cause chronic gastritis.

Helicobacter pylori infection is the main pathogenic factor of gastritis, peptic ulcer, MALT lymphoma and gastric tumor (intestinal gastric cancer). Studies show that 15% to 20% of people infected with Helicobacter pylori will develop peptic ulcer in their lifetime, and 1 ~ 2% of them may develop gastric cancer.

Today, I will focus on five main problems about Helicobacter pylori.

01

How to detect Helicobacter pylori?

There are three methods to detect Helicobacter pylori, including blood test for antibody, gastroscopy sampling and C breath test. There are false positives and false negatives in blood test for Helicobacter pylori antibody. Antibody-positive only means that you have been infected with Helicobacter pylori, but not the current infection status, so antibody detection is not accurate.

However, gastroscopy may also affect the test results if the materials are too small and biased. Among all detection methods, C13 or C14 urea breath test is the "gold standard", which is the most accurate and convenient. However, it should be noted that proton pump inhibitors should be used for 2 weeks, and bismuth and antibacterial drugs should not be tested for 4 weeks.

02

Does helicobacter pylori positive have to be sterilized?

According to the latest report of the Sixth National Consensus on Treatment of Helicobacter Pylori Infection (Non-eradication Treatment Part) released in May 2022 (hereinafter referred to as the National Consensus), only two groups of people are strongly recommended for sterilization, peptic ulcer and gastric mucosa-associated lymphoid tissue lymphoma.

The recommended sterilization population includes: chronic active gastritis, gastric hyperplastic polyp, HP infection with dyspeptic symptoms, post-ESD, family history of gastric cancer, long-term use of NSAID, long-term use of proton pump inhibitors, unexplained iron deficiency anemia, primary immune thrombocytopenia, vitamin B12 deficiency and other diseases.

Anti-Helicobacter pylori treatment is not needed for the elderly over 80 years old, patients with serious chronic diseases and children under 14 years old without peptic ulcer and dyspepsia. At present, there are different opinions on whether it is necessary to eradicate HP in patients with obesity, inflammatory bowel disease and asthma.

03

Will it be infected again after anti-Helicobacter pylori?

After the eradication of Helicobacter pylori infection, the actual recurrence rate is not high, and the annual recurrence rate is only 4%-5%. The five-year recurrence rate is about 10%. In fact, many people have not really achieved eradication because of drug resistance and other reasons, which is not a recurrence.

04

What is the latest treatment plan for Helicobacter pylori?

In the National Sixth Consensus in 2022, the dual regimen of high-dose antibiotics combined with proton pump inhibitors was written into the guideline for the first time as the preferred recommendation for the first and second treatment. Specifically: high-dose amoxicillin (750mg once, 4 times a day)+voronoxacin (20mg twice a day) for 14 days. Provided that penicillin is not allergic.

05

Is the toothpaste for treating Helicobacter pylori sold on the Internet really effective?

The so-called toothpaste for the treatment of Helicobacter pylori in the market can not eradicate Helicobacter pylori, but only has a certain effect on bacteria in the oral cavity. Toothpaste is not an antibiotic, and it cannot be absorbed into the blood and gastrointestinal tract. It lacks the most basic pharmacological basis for eradicating Helicobacter pylori and is not supported by relevant evidence-based medical evidence.

Ai Yuejin, a 59-year-old professor at Nankai University, died and was the founder of Nankai military discipline.

Ai Yuejin data map

On April 22nd, The Paper (www.thepaper.cn) was informed by Ai Yuejin students and the Propaganda Department of Nankai University Party Committee that Ai Yuejin, a professor and doctoral supervisor of Marxist College of Nankai University and the founder of military discipline of Nankai University, died in Tianjin at 22: 18 on April 21st, 2016 at the age of 59.

In addition, Ai Yuejin also served as the deputy director of the Military Teaching Steering Committee of Tianjin Higher Education Institutions, the vice president of Tianjin Sinology Research Association, and the director of Tianjin National Defense Education Association.

According to publicly reported information, Ai Yuejin, born in 1958, after graduating from Nankai University, stayed in school to work in the Youth League Committee, and then set up a military teaching and research section. In 2006, Ai Yuejin successfully applied for the only master’s degree in military science in non-military colleges in China, and was the founder and academic leader of Nankai University.

In addition to military thought, Ai Yuejin’s main research fields include international situation and hot issues, eloquence, etiquette, success, leadership, quality development and professional ethics, etc. He has served as a judge of the National College Debate of CCTV and the Beijing Finals of the International University Debate Competition.

Since January, 2016, the original major of "Military Science and Military Thought" in Nankai University has been changed to the major of "Study of Marxism in China" in Nankai Institute of Marxism Education, and Ai Yuejin continues to be the tutor of master and doctoral students. The research direction of this major is Mao Zedong’s military thought, and it enrolls 4 master’s students and several doctoral students every year.

In an interview with Ai Yuejin in 2009, The Daily News questioned that "some people think that some of your (Ai Yuejin’s) views are somewhat random, and some of your arguments are not reliable, even copied from tabloids".

In response, Ai Yuejin said, "I have read some materials, made choices, used them for me, and can justify myself. This is normal in academic circles. Of course, I will try my best to be objective, but everyone has his own ideas, and no one can interfere in this. I am just a teacher or a speaker, not a preacher, not a saint. What I say does not have to be recognized and accepted by all people, and that is impossible. "

Later, Ai Yuejin also stressed, "I don’t want to be a panacea, and the goal of the sage is too high, but as far as my personal philosophy and personality are concerned,’ drilling only one door’ is not my philosophy, so I have to continue to work hard."

New progress has been made in domestic large aircraft! On December 26th, the world’s first C919 started its verification flight.

On December 26th, the world’s first large domestic C919 aircraft will start its 100-hour verification flight. After the successful completion of the verification flight, the first C919 is expected to meet the requirements of the Civil Aviation Administration as early as the spring of 2023 and put into commercial passenger operation.

As a new generation of large aircraft independently developed by China, what tests has C919 experienced? When can I take it?

Project establishment → First flight → pay

The "big plane dream" is gradually realized

In 2007, a major special project for large aircraft was formally established. After many years, step by step, the "big plane dream" is gradually realized.

It is expected to break the market monopoly pattern.

For a long time, the global civil large passenger aircraft market has been monopolized by Boeing and Airbus. With the delivery of C919, the monopoly pattern of the global civil large passenger aircraft market is expected to be broken.

Wu Guanghui, chief designer of C919, said, "It is estimated that in the next two decades, the number of aircraft in China will double, and the number of aircraft in the world will probably double. In this incremental case, it can fully accommodate our third and fourth markets. The market is win-win cooperation, and our customers need more choices. "

△ On November 8, 2022, in Zhuhai, Guangdong, C919 appeared at Zhuhai Air Show and performed an air show.

On November 8th, C919 made its first flight show at the 14th China International Aviation and Aerospace Exhibition. This wonderful appearance also ushered in an order for 300 aircraft. As of December 12th, C919 has won 1176 orders from 28 customers at home and abroad.

Explore the road of independent innovation

Large aircraft is the symbol of high-end manufacturing industry, and the industrial chain involves nearly 300,000 industrial personnel from more than 1,000 domestic enterprises, universities and research institutes.

The research and development of C919 has achieved 163 key technological breakthroughs. With the use of many new technologies and materials, C919 is expected to lead the rise of domestic high-end manufacturing industry after commercial delivery.

△ Aircraft landing gear requires extremely high material strength and toughness, leading the industrial development of ultra-high strength steel.

In terms of shape design, unlike the six windshields of traditional aircraft, the C919 only uses four windshields and adopts curved surface design. This can provide a broader vision for the pilot, and smoother nose lines can help the aircraft reduce air resistance and make the aircraft more fuel efficient.

Moreover, the C919 is equipped with the supercritical airfoil independently developed for the first time in China, which can effectively reduce the flight resistance compared with the traditional airfoil.

The key core technology "can’t come, can’t get it, can’t buy it". The successful development of C919 has explored the development path of China design, system integration, global bidding and upgrading localization. Independent innovation makes us more confident!

15 years to overcome difficulties and achieve national success.

Behind the blue sky of C919, the R&D team has experienced many tests.

Race against time! They implement the "611" and "724" working modes.

Since 2008, Wu Guanghui, the chief designer of C919, has led the team to race against time from scratch. He took the lead in implementing the working modes of "611" and "724": "611" means working 6 days a week and 11 hours a day; "724" refers to working 7 days a week and 24 hours a day during the critical period of tackling key problems.

Working hard day after day, the staff provided a solid guarantee for the independent innovation and research of China’s large aircraft and the safe flight of the C919.

The young team independently tackled the C919 and had the "China brain".

During his 14 years as chief designer of C919, Wu Guanghui led the team to overcome more than 100 key technical problems, among which flight control law is one of the most difficult projects.

The flight control law is equivalent to the "brain" of the aircraft, which fundamentally determines the degree of control of the flight process and helps pilots to operate the aircraft.

Zheng Xiaohui, head of the control law research team, said that in the early stage of research and development, the team was composed of young members with an average age of only 30 years old. They resisted the pressure and faced the difficulties.

Ten years later, the control law has finally changed from technical indicators and three-dimensional drawings to a complete system, and the C919 has the "China brain".

After five years of flight test, C919 was qualified for delivery.

Type certificate, production license and single-machine airworthiness certificate are required for the delivery of an aircraft. At present, C919 has obtained three certificates issued by the Civil Aviation Administration of China.

C919 has been tested and tested for five years from its first flight to delivery.

It needs to explore the risks of the new aircraft during the flight test, find out the performance limit of the aircraft under special conditions or conditions, and determine the boundary "red line" for safe flight.

For example, pilots need to fly in high-risk subjects such as stall and minimum ground speed. If they are not careful, the consequences will be unimaginable. This test flight verification is also called "dancing on the tip of a knife".

Take advantage of the wind and flap your wings in the blue sky.

Looking forward to the domestic large aircraft C919

Verify that the flight trip was a complete success!

How far is a cup of milk tea with passion fruit "online celebrity" from "Industry Red"

  Passion fruit has become a new option to promote industrial poverty alleviation in many places because of its quick effect and good market. However, people in the industry reminded that passion fruit seems to be easy to grow and manage, and some misunderstandings still need to be clarified. Both growers and social capital will pay "tuition fees" for blindly following the trend and short-sighted behavior. Nowadays, passion fruit is in an "outbreak period", but it is not normal that the demand exceeds the supply. It is necessary to extend the industrial chain by developing deep processing and balance the supply and demand relationship of the whole industry. With the processing guarantee, the planting risk can be effectively reduced, and the fruits planted by farmers will at least not rot in the fields.

  Xinhua Daily Telegraph reporter Tu Hongchang and Cao Yiming

  Before returning home to start a business in 2015, 47-year-old Qiu Chunsheng was an agricultural layman who had never even heard of paraquat. Today, he has rented more than 50 acres of passion fruit in Wukeng Village, Tufang Town, Changting County, western Fujian.

  Speaking of the ups and downs of this "fashionable" fruit in the past three years, Qiu Chunsheng used a metaphor: "Doing agriculture is like driving a car. Novices are very excited and drive faster and faster. Only when they suffer losses will they slow down and calm down."

  In Tufang Town, which is known as "the hometown of betel nut and taro", it is a fresh experiment for Qiu Chun to grow passion fruit. In 2016, the market was good. The field price of a pound of fruit was as high as 15 yuan, and Qiu Chunsheng, who had planted 10 acres, made a small profit. In 2017, Laoqiu expanded the planting area, and led several poor households to find a 250,000 yuan discount loan for poverty alleviation from the bank. I didn’t expect that the early frost that started in October "deducted" more than 200,000 kilograms of fruit in the field. After losing all his money, he was once advised to "run away".

  Qiu Chunsheng named his farm brand "Hakka Lang". Adhering to the Hakka’s hard-working, hard-working and unyielding character, Laoqiu reluctantly sold a house accumulated from working outside for more than 10 years to repay the loan, and continued to plant passion fruit this year. At present, it is the season of fruit picking, but what bothers Lao Qiu is that after three years of continuous planting, passion fruit appears "taboo phenomenon", not only the fruit output is less than in previous years, but also the size is much worse.

  Qiu Chunsheng has been to Taiwan Province, Guangxi and other places for more than three years to plant passion fruit in his hometown, but he said that he is still a "primary school student" in the groping stage. Speaking of the increasingly hot passion fruit planting trend in recent years, he said meaningfully: "No matter how beautiful the orchard is and how many people visit it, it is eye-catching. Earning real money and silver is the last word."

  Passion fruit has become a "online celebrity" like crayfish.

  Passion fruit first became popular in tea shops in Fujian, Guangdong and other places. Young people have a high acceptance of this unusual sweet and sour juice. Later, the saying that passion fruit can relieve alcohol, greasy and even lose weight became popular.

  Passion fruit, also known as passion fruit, belongs to passion fruit family, originated in South America, and is a perennial evergreen climbing woody vine. It belongs to tropical and subtropical fruit, likes light and adapts to sunny and warm climate. Planting in the same year can be harvested in the same year, and the general fruit picking period is more than half a year.

  In the memory of Shi Qing, the chief expert of Fujian fruit industry technology system, passion fruit is not a new fruit variety. As early as the 1990s, passion fruit was introduced from Taiwan Province in Zhangzhou, southern Fujian, and it was on a small scale. However, due to the prevalence of stem rot and insufficient market development, this industry gradually fell silent. Until these two or three years, passion fruit quickly warmed up again, and the planting area of each producing area soared.

  "Passion fruit first became popular in tea shops in Fujian, Guangdong and other places. Young people have a high acceptance of this unusual sweet and sour juice. Later, it became popular that passion fruit can relieve alcoholism, greasy and even lose weight, and passion fruit became like crayfish ‘ Online celebrity ’ Products. " Han Jie, planning director of Hongdao Jingbang, said.

  Hongdao Jingbang is a brand planning company focusing on large-scale agriculture and healthy food. According to the investigation and analysis in Han Jie, there are two important backgrounds for the prosperity of passion fruit industry: one is the rise of two provincial-level characteristic industries with Guangxi and Fujian as the core, and the latent publicity of passion fruit by retail industries such as tea shops has gradually completed the cognitive education of domestic consumers on passion fruit categories.

  The second is the thrust of consumption upgrading. Passion fruit’s unique sweet and sour taste and current convenient e-commerce channels have promoted Tmall’s monthly sales of 180,000 pens; Passion fruit traded through e-commerce and WeChat platform in Fujian is close to 80% of the sales volume in the whole province, which shows that passion fruit has high consumer demand, high repurchase rate and a consumption base is taking shape.

  Wu Ji, head of the Passion Fruit Production Cooperative in Puli, Nantou County, Taiwan Province, said that the history of passion fruit cultivation in Taiwan Province is more than 80 years, and the production area is concentrated in Puli Town, Nantou County, accounting for about 80% of the total planting area of 9,000 mu in Taiwan Province. The island’s fresh fruit sales are booming all the year round, and it has become the most stable fruit species in the local planting industry so far.

  Optimistic about the land space and market potential of the mainland, Wu Ji currently has passion fruit seedling bases in Xiamen and Nanping, Fujian. He told Xinhua Daily Telegraph that when he came to the mainland five years ago, many people knew nothing about passion fruit, but now their seedlings are often in short supply.

  Passion fruit has become a new option to promote industrial poverty alleviation in many places because of its quick effect and good market. Lu Xiaoping, director of the Office of Guangxi Zhuang Autonomous Region Fruit Production Technical Guidance Station, said that passion fruit was planted in Guangxi in the 1990s on a very small scale. In recent years, with the development of precision poverty alleviation work in various parts of Guangxi, passion fruit has become a poverty alleviation industry introduced in many areas. By the end of 2017, the planting area of passion fruit in Guangxi was 29. 990,000 mu, the output reached 24. 630,000 tons, with an output value of about 1.2 billion yuan.

  In Beiliu City, Yulin, Guangxi, the hometown of passion fruit, the per capita income of poor households who planted passion fruit increased by 2,100 yuan to 3,360 yuan in 2017, and 19% of poor households in the city achieved the goal of poverty alleviation by planting passion fruit or taking shares in passion fruit industry.

  In recent years, Fujian has also listed passion fruit as a new characteristic agricultural industry. In 2017, the planting area of passion fruit in Fujian exceeded 150,000 mu, the output was 180,000 tons, and the output value exceeded 3 billion yuan, both of which were more than twice that of 2016. This year, the planting area in various places is still increasing.

  Shi Qing said that Fujian has good hydrothermal conditions, large temperature difference between day and night, and many hilly landforms, which is very suitable for producing high-quality passion fruit. Compared with other places, the characteristics of Fujian passion fruit can be summarized as "four highs and one specialty", that is, high aroma, high face value, high nutritional value, high edible rate and unique flavor. In September 2017, Fujian Passion Fruit was certified as a national geographical indication of agricultural products, covering the whole province of Fujian.

  In order to expand the popularity of passion fruit in Fujian, Fujian has held special promotion activities for two consecutive years. The main leaders of the provincial party Committee and the provincial government "endorsed" Fujian Passion Fruit, and "Fushan Fushui produces a blessing fruit" became a buzzword. At the same time, Fujian launched publicity through new online media such as WeChat WeChat official account and Today’s Headlines, which promoted the popularity of passion fruit online topics. During the meeting of BRICS leaders in Xiamen in 2017, Fujian passion fruit was also put on the table of leaders of various countries.

  Walking on the country road in Wuping County, Longyan City, western Fujian Province, you can see the slogan "Keep fewer pigs and variety of fruits, and plant passion fruit if you want" from time to time. This once-polluted pig breeding town regards passion fruit as a new way for farmers to change jobs and production. With a large reduction in pig breeding, the local passion fruit planting area has grown from more than 600 mu in 2016 to more than 3,000 mu in 2017, and this year it has exceeded 10,000 mu.

  If the yield per mu is more than 1,500 Jin, get full marks, 5 points will be deducted from 1,001 Jin to 1,500 Jin, 10 points will be deducted from 501 Jin to 1,000 Jin, and those below 500 Jin won’t score … … In a passion fruit planting base planned as a poverty alleviation project in minzhu town, Wuping County, Xinhua Daily Telegraph reporter saw a detailed appraisal form for growers.

  Lai Yuyuan, deputy head of minzhu town, said that passion fruit planting and management is not labor intensive, and the income is stable, which is very suitable for some sick and poor households. Local competition mechanism is introduced, poor households claim planting areas, and local agricultural companies provide skills training, technical guidance, product recycling and other assistance, and conduct quantitative assessment on the daily production of poor households. At present, there are 13 poor households in the township involved in planting, with an average of 1. 3 mu, according to the yield of 1,500 Jin per mu, each household has an annual income of 6,000 yuan to 9,000 yuan, and it is not difficult to get rid of poverty.

  With favorable policies and popular market, passion fruit has aroused the enthusiasm of social capital and large growers.

  Speaking of the beginning of his involvement in the passion fruit industry, Liang Xiaoyi, chairman of the Fujian Passion Fruit Production and Marketing Alliance, used the word "mistake" to describe it. When he planted the first passion fruit in 2016, he only thought of increasing green plants for his own driving school. Unexpectedly, after the result, 2 yuan’s price of 100,000 Jin of fruit was quickly robbed by driving school students.

  Liang Xiaoyi became attached to passion fruit and rented more than 130 acres of passion fruit in Minhou, a suburb of Fuzhou. Now it has developed into an ecological experience base integrating research and development, planting, picking and sales. Fujian Kangdasen Green Agriculture Development Co., Ltd., which is chaired by him, was listed as "Fujian Passion Fruit Industry Leading Enterprise" in 2017. So far, the company has invested more than 20 million yuan in the passion fruit industry.

  Luo Fuxing, a big planter in Sanlian Village, zhongshan town, Wuping County, told the reporter that he has been engaged in planting for more than 10 years and has planted navel oranges, chestnuts and pomelos, but he basically didn’t make any money because there are too many same products on the market. Feeling the call of the county, he planted 23 mu of passion fruit last year and expanded it to 54 mu this year. Because of the excellent seedling and planting technology, the yield per mu reached 5,000 Jin, the proportion of medium and large fruits reached 80%, and the listing period was more than 10 days earlier than others. The purchase price reached more than 8 yuan per Jin, and all the money lost in the previous 10 years was earned back. What money? Feeling the call of the county, he planted 23 mu of passion fruit last year and expanded it to 54 mu this year. Because of the excellent seedling and planting technology, the yield per mu reached 5,000 Jin, the proportion of medium and large fruits reached 80%, and the listing period was more than 10 days earlier than others. The purchase price reached more than 8 yuan per Jin, and all the money lost in the previous 10 years was earned back.

  It is not easy to turn "baccarat fruit" into "rich fruit"

  If we only see the hot market of fresh fruit and ignore the extension of industrial chain, the market saturation will face the problem of "selling hard"; At present, passion fruit processing is mainly based on small fruit and secondary fruit raw materials, mainly based on rough processing of juice and preserved fruit, mainly based on small factories and small enterprises, which is not conducive to the long-term healthy development of the whole industry.

  The reporter learned in the interview that the situation is not good behind the passion fruit market is popular and the output is high.

  Variety and confusion of seedlings have become a major drawback of passion fruit planting at present. Wu Ji introduced that there are more than 400 varieties of passion fruit in the world, but most of them are mainly used for ornamental purposes, and few of them can be planted commercially with good adaptability. Taiwan Province cultivated the passion fruit variety "tainungno." in 1970s. This variety is large in size, high in sweetness and high in yield. Today, this variety is almost fully planted in Taiwan Province.

  The agricultural management department of Fujian Province also takes "fine varieties first" as the basic work, and screened and identified two varieties "Fujian Passion Fruit No.1" and "Fujian Passion Fruit No.2" which are suitable for planting in Fujian, with good quality, stable yield and strong resistance, and promoted them as the main varieties in the whole province, with a planting area of over 100,000 mu, accounting for about two-thirds.

  The problem of seedlings is more prominent. According to the agricultural management department of Pingnan County, Guigang City, Guangxi Province, the local passion fruit planting area is close to 20,000 mu, but only one enterprise in the county has a seedling production and operation license, and the seedling production and operation is not standardized enough; At the same time, some seedling production bases only sell seedlings without technical follow-up, and there are many cases of farmers’ planting failure.

  In just a few years, the planting of passion fruit in Beiliu City, Guangxi has grown to more than 40,000 mu, but at present, more than 80% of the seedlings are cuttings, and most of them are directly cut from the production orchard to raise seedlings without going through the disinfection and sterilization procedures, so the quality of seedlings is uneven.

  Yao Wenhui, director of the Planting Management Office of Fujian Provincial Department of Agriculture, said: "If the quality of seedlings is not solved, virus seedlings will fly all over the sky. The more you plant, the greater the risk of disease, which will hurt the whole passion fruit planting industry."

  Guo Dexiang, secretary-general of Fujian Passion Fruit Production and Marketing Alliance, believes that passion fruit seems to be easy to grow and manage, and the current market is good. However, from the perspective of benign industrial development, some misunderstandings need to be cleared up urgently. Whether it is growers or social capital, blind follow-up and short-sighted behavior will pay "tuition fees" and costs.

  Regardless of climate and altitude conditions, following the trend of planting leads to "only flowering but not fruiting", unwilling to "plant once a year" to save costs, leading to virus epidemic, close planting for high yield and abuse of chemical fertilizers and pesticides leading to fruit decline, and unconventional expansion of planting area leading to financial strength failing to keep up with … … Cao Biyong, deputy general manager of Kangdasen Green Longyan Branch, told reporters about the "pits" he had seen in the development of passion fruit industry.

  Cao Biyong said that passion fruit, commonly known as "egg fruit", has the same shape and characteristics as an egg, which shows that it is precious to protect it. It is not easy for passion fruit to become a "cash cow" and a "rich fruit", which involves many links such as seedling, planting, quality control, picking, sorting, logistics and sales. Any problem in any link may affect the income.

  "Don’t worry about no fruit, I’m afraid there will be no good fruit!" Cao Biyong gave two examples to the reporter. First, the average yield per mu of passion fruit in Fujian is about 2,000 Jin, but if it is really well planted, the yield per mu can exceed 6,000 Jin, and the planting level is different, and the rate of large and medium-sized fruits may be doubled; Second, from the perspective of sales, if it is a good fruit, a catty of 10 yuan will be sold in 15 yuan, and there will be no worries about selling or making money; If it is the second fruit, a catty of 3 yuan is sold in 4 yuan, and the more it is sold, the worse it will be.

  Fujian Longyan Lianmi Ecological Agriculture Development Co., Ltd. is a processing enterprise specializing in the production of frozen passion fruit juice, with an annual output of 3 million tons of juice and consumption of 1,000 tons of passion fruit raw materials. Zheng Zhenjiang, the person in charge of the company, said that passion fruit is in an "outbreak period" at present, but in the long run, the demand is not normal. It is necessary to extend the industrial chain through deep processing and balance the supply and demand relationship of the whole industry. With the processing guarantee, the planting risk can be effectively reduced.

  It is understood that at present, the planting area of passion fruit in Longyan City, Fujian Province is close to 70 thousand mu, but there are only five processing enterprises, and the scale is small; The annual output of passion fruit in Pingnan county of Guangxi is about 6000 tons, but there is basically no deep processing.

  Some insiders said that if we only see the hot market of fresh fruits and ignore the extension of the industrial chain, the market saturation will face the problem of "selling hard"; At present, passion fruit processing is mainly based on small fruit and secondary fruit raw materials, mainly based on rough processing of juice and preserved fruit, mainly based on small factories and small enterprises, which is not conducive to the long-term healthy development of the whole industry.

  Liang Xiaoyi believes that passion fruit is a veritable "passion fruit". In addition to processing fruit juice and preserved fruit, it can also be made into fruit vinegar, fruit wine, jam, and can also be matched with milk, drinks, cakes, bread, chocolate, etc. At present, relevant products have been listed, and the next step is to improve the processing technology and make it a large-scale and brand. If it develops well, the deep processing of passion fruit will be a "blue ocean", which can completely create "explosive" products of passion fruit in the market.

  Liang Xiaoyi said that the passion fruit industry now belongs to the stage of "big face and unhappy legs". It has a good reputation, is favored by the market, and has a large demand. However, the supply of high-quality production capacity is insufficient, and the quality of fruits varies greatly from place to place, and the planting norms and quality standards need to be strengthened.

  Wu Ping, a person in charge of e-commerce in Beiliu City who has been engaged in passion fruit sales for many years, told reporters that their online shop can sell passion fruit all year round through its own planting base and cooperation with surrounding villagers. However, at present, the competition of e-commerce is very fierce, and price wars occur from time to time, which leads to the decline of e-commerce income, which in turn affects the interests of farmers.

  Wu Ping said that due to the different quality of passion fruit sold by e-commerce and the lack of uniform quality rating standards in the local industry, the passion fruit sales market is mixed, which will inevitably affect the consumption experience of foreign consumers in the long run, which will also affect the overall reputation of passion fruit in Guangxi.

  Han Jie believes that there is still great potential in the market space of passion fruit under the background of the current trend of "losing fruit from the south to the north" and the consumption upgrading of young people. For example, at present, the popularity and sales of passion fruit are not high in the main fruit consumption markets such as Shanghai and Hangzhou. At the same time, with the increase of output, the competition of passion fruit in origin, brand and marketing channel will become more and more fierce, and there will be obvious word-of-mouth and market differentiation in three to five years.

  How to avoid the mistake of "the same goods" and "a gust of wind"

  In the past, there was a misunderstanding in developing agriculture, that is, blindly emphasizing "bigger and stronger" regardless of objective conditions. Characteristic agriculture should work hard on the word "special", not blindly expand the area and output, but "less but fine" and "fine but strong", and win by quality and characteristics

  After paying the "tuition fee" for three years, Qiu Chunsheng had a new understanding of modern agriculture through passion fruit: "I used to think that young people engaged in agriculture was very ‘ Cool ’ , now I feel really ‘ Bitter ’ ; I used to think that planting techniques could be learned, but now I find that land is the best teacher.

  "To promote the revitalization of rural industries, the government should guide and support it, but it can’t cover all the world and cure all diseases." Chen Mingwang, deputy director of the Fujian Provincial Department of Agriculture, said that Fujian’s agricultural management departments do not make plans or set targets for passion fruit planting, and the special support funds of 10 million yuan each year are used for the most urgent standardized planting demonstration and seedling base construction, which plays the role of "yeast" instead of "pepper noodles". How much to plant, how to sell, and how to expand profits in various places, the government does not interfere too much, allowing enterprises to rush to the market and drive the whole industry to catch fire and live.

  "Characteristic agriculture is a comprehensive reflection of the right time, the right place and the agricultural production. Irreplaceability and reproduction are one of its important features. " Zhu Qizhen, a professor at China Agricultural University, said that there was a misunderstanding in developing agriculture in the past, that is, blindly emphasizing "bigger and stronger" regardless of objective conditions and blindly copying. As a result, the output went up and the quality came down, which led to painful lessons such as overproduction, environmental overload and poor crops hurting farmers.

  Zhu Qizhen believes that characteristic agriculture should work hard on the word "special", not blindly expanding the area and output, but "less but better" and "better and stronger", and win by quality and characteristics. Specific to the passion fruit industry, each producing area should highlight its own environmental characteristics, species resources characteristics and climate characteristics, and don’t repeat the mistake of "goods all the way" and "a gust of wind".

  There were two landmark events in the development of passion fruit industry in Fujian in 2017: First, the whole province was included in the protection of geographical indications of national agricultural products; Second, the Fujian Passion Fruit Production and Marketing Alliance led by leading enterprises was established.

  Guo Dexiang said that these two incidents reflected the urgency and efforts of the transformation and upgrading of Fujian passion fruit industry, that is, improving the technology and information closure under the small-scale peasant economy model, kneading the strengths of seedlings, planting, sales, processing and promotion, promoting the integration and development of the primary, secondary and tertiary industries, and turning the advantages of origin into market advantages and brand advantages.

  According to reports, the Fujian Passion Fruit Production and Marketing Alliance has linked the major passion fruit enterprises and large growers in the province, forming a development pattern of "production and marketing alliance+company+association+farmers", sharing product quality management, expert service system, brand culture construction, Internet e-commerce data public opinion, etc., to achieve "group development".

  "Holding a group" has expanded the right to speak in the production area of passion fruit in Fujian and won the attention of e-commerce giants. In June this year, Fujian Passion Fruit Production and Marketing Alliance reached a strategic cooperation with Alibaba, focusing on building the "Passion Fruit Precision Poverty Alleviation Project in Changting County" and the "Wuping Passion Fruit Going to Sea Project", in which Alibaba supported the "cash+flow" of the passion fruit industry in Changting County, an old revolutionary area. Wuping Passion Fruit Offshore Project plans to invest 21.5 million yuan, increase output by 5,000 tons, and expand the overseas market of Fujian Passion Fruit.

  "Whether it is a poor household, a big grower or an agricultural company, it is necessary to make money in the end." Cao Biyong said that from the current development stage of Fujian passion fruit, thanks to the support of policies, industries and finance and the rising market, the income of small-scale planting is relatively stable; The income of skilled planters is considerable; Leading enterprises need large capital investment in purchasing and storage, equipment, management, operation and other aspects, and they still need to "struggle" for some time.

  Some interviewed experts and people in the industry believe that a key factor for a new agricultural industry like passion fruit to achieve long-term healthy development is to rationalize the benefit distribution mechanism among small households, large households, small enterprises and large enterprises. Different parties have different resources and advantages, and their benefit expectations are also different. For example, enterprises that have the advantages of output and channels implement "protective prices" and make appropriate profits for fruit farmers, which will help protect the enthusiasm of fruit farmers and make the whole industry better and stronger in the long run.

  "The key to an industry is to rely on people and talents." Guo Dexiang said that it is gratifying that more and more young people are now involved in the passion fruit industry. For example, the average age of the members of Wuping Gold Passion Fruit Association is only 35 years old, and many of them are new professional farmers with college degrees. They have strong adaptability to modern agricultural production technology and the trend of "Internet+Agriculture", which is conducive to industrial promotion and upgrading.

  Wang Xiuzhen, a girl from Wuping, born after 1985, is the head of the local Passion Fruit Association. After graduating from college, she spent many years in Beijing, Fuzhou and other places, and returned to her hometown to start a business in 2013. She said that she is "fully committed" to Passion Fruit: she spends more than half of her time running to the countryside and fields every year; Every day, I browse information in more than 20 passion fruit WeChat groups and am busy taking orders online.

  "Our Wuping forest coverage rate is close to 80%. Passion fruit grew up in an oxygen bar, and its quality is very good. Price and sales are not a problem." Wang Xiuzhen said that the annual sales of passion fruit in her current company has exceeded one million yuan, and at the same time, she has helped more than 10 poor growers in pairs.

Health and Health Commission: Vaccination of influenza vaccine can be scheduled and deployed in time to better ensure the use of the people.

  Cctv newsOn January 25th, a press conference was held in National Health Commission to introduce the prevention and control of infectious diseases in winter and spring and the prevention and response of common diseases during festivals. When answering a reporter’s question, the relevant responsible comrades of the Health and Health Commission and the first-line medical experts said that the supply of vaccines is adjusted at any time, and there is no such situation that individual places are always nervous.

  Reporter: What are the main types of influenza viruses this year? How dangerous is it compared with last year? Now it has become a hot topic on the Internet. Are there some misunderstandings or excessive panic among the masses? Are there any new measures for prevention and control this year? Are there any new measures on the vaccine?

  Li Zhongjie, a researcher at the Center for Disease Control and Prevention of China: There are four types of influenza viruses: A, B, C and D. There are two kinds of seasonal influenza that can spread continuously in the population: A and B. According to the monitoring results of influenza virus in winter and spring by the national influenza surveillance network, influenza A (H1N1) is the main epidemic at present, with influenza A accounting for the vast majority, more than 90%, and influenza B is very low.This year’s epidemic pathogens are very well matched with the influenza vaccine strains we recommend to vaccinate.Through the antigenicity monitoring of influenza virus, we have not found any changes in antigenicity that affect the epidemic of influenza this year, soThe vaccine has a good protective effect on this year’s flu.

  Seasonal influenza is the stage of high incidence of people in winter and spring. This year’s monitoring of hospitalization, including the monitoring of severe cases, did not suggest a significant increase or abnormality. Seasonal influenza is a common disease in the population, and it is a disease that people are generally susceptible to. What needs to be paid attention to is thatChildren under 5 years old, especially children under 2 years old, elderly people over 65 years old and patients with chronic diseases such as chronic respiratory system, chronic diabetes and cardiovascular system, have a higher risk of complications, so special attention should be paid to preventing influenza.China CDC issued guidelines for influenza vaccination before the arrival of the epidemic season in 2018, which focused on strengthening protection for these groups of people and made relevant suggestions.

  Song Shuli, spokesperson of the National Health and Wellness Committee and deputy director of the Propaganda Department:Our supply of vaccines is adjusted at any time, and there is no such situation that individual places are always nervous.andVaccination can be made by appointmentYes, by making an appointment to understand the demand more accurately, you canPut the vaccine in place in time, so as to betterEnsure that the people have access to vaccines.

Google’s Gemini function was shut down urgently, and word of mouth collapsed overnight. Yann LeCun: I knew it for a long time.

Original attention to the heart of the machine of the big model

Machine heart report

Editor: Xiaozhou, Zenan

Gemini seems to have finally been played badly.

At the end of last year, Google Gemini shocked the industry. It is Google’s "largest, most capable and most versatile" AI system. It claims to be the first native multi-modal large model, and its ability surpasses GPT-4. It is also considered as a powerful tool for Google to counterattack Microsoft and OpenAI.

In this regard, on February 8, Google also renamed its own service Bard for benchmarking ChatGPT as Gemini to highlight its new mission-to provide access to the "strongest model series". Last week, Google also.

As a result, less than a month after its launch, this Gemini overturned.

How outrageous, as a multi-modal generation model, Elon Musk generated by Gemini is like this:

The faces and expressions are vivid, but there is a big question: how did you become black?

Another attempt was made to get Gemini to draw a picture of German leaders in the 1940s. As a result, AI gave this picture:

Many netizens on social networks also provided some samples of Gemini-generated Vikings and Popes. We can see an Asian woman dressed as a pope, but all popes in history are men.

In a word, when many users use the portrait generation service, they find that Gemini seems to refuse to depict white people in the image, so that many pictures that violate the basic facts (gender, race, religion, etc.) are generated.

In the past, most of the image generation models were criticized for generating "white" images, but Gemini overcorrected them?

In reddit’s doo-doo area, netizens also started to play tricks, such as asking Gemini to generate an "Iron Man" Robert Downey Jr.:

Just tell me if it’s the same.

However, Gemini is not always so biased, and sometimes the characters in the images it generates become white. For example, Clarence Thomas, Justice of the Supreme Court of the United States, the result generated by Gemini is as follows:

However, he is actually African-American.

A picture of Clarence Thomas himself.

How did Gemini’s prejudice turn 180 degrees when it came to the special profession of judge?

These pictures are true and false, and spread quickly on social media like a virus. Musk’s own attention further expanded the impact of the incident. He said sternly that Google "played too much" on Wensheng map.

With the increasing rhythm, many AI experts have begun to express their views. Yann LeCun, winner of Turing Prize, said today that he had expected it.

He said that as early as four years ago, his comments on the super-resolution of GAN portraits were fiercely opposed by everyone. However, it is an obvious fact that the task of image reconstruction will be affected by the serious deviation of training data set statistics.

LeCun also cited a study entitled "Studying bias in gans through the lens of race" by the AI Summit ECCV 2022, which pointed out that the performance of generating image models would be affected by the ethnic composition in the training data set.

The research shows that the racial component of the generated image successfully inherits the racial component of the training data, and the race and quality of the generated image are also different-the annotator always prefers the white image generated by AI.

LeCun retweeted the post from Aravind Srinivas, CEO of Perplexity AI. The latter said that the data deviation caused problems in the output of the model, and Google went too far in the opposite direction, so that they made a big mistake in Gemini.

Google: We were wrong and promised to improve.

Under heavy pressure, Google admitted the problem of Gemini image generation on Thursday.

The following is the latest response from Prabhakar Raghavan, Senior Vice President of Google Knowledge and Information, to the "rollover" of Gemini images:

Three weeks ago, we launched a new image generation function for the Gemini dialogue application (formerly known as Bard), including the function of creating people’s images.

Obviously, this function did not meet expectations. Some generated images are inaccurate and even aggressive. We thank the users for their feedback, and we are sorry that the function didn’t work properly.

We have admitted this mistake, suspended the function of generating people’s images in Gemini, and we are developing an improved version.

Google said that the Gemini dialogue application is a specific product independent of Google’s search, underlying artificial intelligence model and other products. Its image generation function is based on the artificial intelligence model Imagen 2.

When building the image generation function for Gemini, Google adjusted it to ensure that it would not fall into some traps we have seen in image generation technology in the past, such as creating violent or explicit images or depicting real people in real life.

Since Google users come from all over the world, the company hopes that Gemini can provide good service for everyone. When generating a person image, the user may not only want to generate a person image of one race (or any other characteristics).

If you prompt Gemini for a specific type of character image-such as "black teacher in the classroom", "white veterinarian with dog" or people in a specific cultural and historical background, users should definitely get an answer that accurately reflects human requirements.

So what’s wrong with Gemini?

In short, there are two things. First of all, Google’s adjustment to ensure that Gemini displays a series of characters fails to take into account the scope that obviously should not be displayed. Secondly, over time, the model becomes more cautious than the developer expected, and refuses to answer some prompts-it will mistakenly interpret some prompts as sensitive.

These two things lead to over-output of the model in some cases, and over-conservative in other cases, which leads to some errors in the image generation function of Gemini.

Google said, "This is not our original intention. We don’t want Gemini to refuse to create the image of any particular group. We don’t want it to create inaccurate historical images or any other images. Therefore, we have turned off the function of generating people’s images and will try to improve it before turning it back on. This process will include extensive testing. 」

One thing to remember is that Gemini is a tool of creativity and productivity, and it may not always be reliable, especially when generating images or texts about current events, developing news or hot topics, it may make mistakes. As we all know, illusion is a challenge that all large language models (LLM) will face, which needs continuous efforts to improve.

We can’t guarantee that Gemini will not occasionally produce embarrassing, inaccurate or offensive results, but we can guarantee that we will take action as long as problems are found. Artificial intelligence is a new technology, which is helpful in many aspects and has great potential. We are doing our best to promote its development safely and responsibly.

Despite all kinds of criticisms such as "Demo plus stunts" and copying training data from Baidu and ERNIE Bot, Gemini has always been highly anticipated by Google. However, the problems in the generated content have caused people a very bad impression, and I don’t know how to remedy them.

On the other hand, this may also reflect OpenAI’s emphasis on security and its foresight in establishing Red Teaming Network.

Can a large-scale model like Gemini make up for this defect quickly?

China’s economic market in 2008 (economic focus)





  


    In 2008, China’s economy maintained a growth rate of 9% in spite of difficulties, and its contribution to world economic growth exceeded 20%.


    In the fourth quarter, although the GDP growth rate took a sharp turn for the worse, in December, there were some positive changes in money and credit, consumption, investment, export and industrial production …


    After experiencing several rare natural disasters in history and the test of the world economic recession caused by the American financial crisis, what kind of overall evaluation should be given to China’s national economy in 2008?


    How to evaluate the overall economic performance throughout the year?


    Ma Jiantang, director of the National Bureau of Statistics, who made his debut at the press conference of the State Council Information Office, was considerate, bringing not only detailed statistical data, but also his overall evaluation of the national economy in 2008: rapid growth, price stabilization, structural optimization and improvement of people’s livelihood.


    At first glance, it is growing rapidly. According to preliminary accounting, GDP in 2008 increased by 9% over the previous year. Although vertically, it is 4 percentage points lower than the growth rate of 13% in 2007, compared with other countries in the world, the growth rate of 9% is still a relatively high speed. According to the latest estimate of the International Monetary Fund, the average growth rate of the world economy in 2008 was 3.7%. According to Ma Jiantang, it has been calculated that in 2008, China’s economy maintained a growth rate of 9% in spite of difficulties, and its contribution to world economic growth exceeded 20%.


    Second, look at the price stabilization. In February, the price rise reached a peak, and the CPI rose by 8.7% that month. China government has taken a series of measures to increase supply, regulate demand, invigorate circulation and increase subsidies for low-and middle-income people. With these measures in place, it took about half a year to control the inflation rate from 8.7% to less than 5%, and it dropped to 1.2% in December.


    Third, look at structural optimization. While the national economy has achieved rapid growth, the primary industry, especially agriculture, has developed well. In 2008, China’s total grain output and unit yield both reached the highest level in history, with grain reaching 1,057 billion Jin. "In such a difficult time, a bumper harvest of grain can be achieved, which further proves that Chinese can support itself, which is also the greatest contribution to the world." As a doctor of economics, Ma Jiantang still remembers the debate about "Who will feed China" provoked by some foreign economists a few years ago. In addition to the industrial structure, the regional structure is also being optimized. Last year, the investment and industrial growth rates in the central and western regions were faster than those in the east.


    In 2008, energy conservation and emission reduction also made positive progress. From the perspective of energy consumption per 10,000 yuan GDP, it decreased by 4.21% in 2008. In the first three quarters of last year, sulfur dioxide emissions decreased by 4.2% and chemical oxygen demand emissions decreased by 2.7%. All these data indicate that China’s economy has made positive progress in building a resource-saving and environment-friendly society while overcoming difficulties and growing steadily.


    Fourth, see the improvement of people’s livelihood. In 2008, the annual per capita disposable income of urban residents increased by 14.5%, with an actual increase of 8.4%; The per capita net income of rural residents increased by 15% in nominal terms and 8% in real terms. It is not easy to maintain such growth under such severe economic conditions. At the same time, social security is increasing. In 2008, the total income of five insurance funds, including basic pension, basic medical care, unemployment, work injury and maternity insurance, was 1,380.8 billion yuan, an increase of 27.7%. The basic pension level and the minimum wage level of enterprise retirees all over the country are improving.
