The Olympic menu no longer has ridiculous English translations.


Husband and wife lung film (data picture)


  Starting from June 12th, all three-star hotels in the eighth district of Beijing can get the English Translation of Chinese Menu from the Catering Management Office of the Tourism Bureau, and more than 2,300 Chinese dishes finally have their own fixed names. From now on, foreigners coming to Beijing will no longer be "on tenterhooks" about ordering Chinese food. However, the English translation of these Chinese dishes has gone through a difficult process from ridiculous to standardization and regularization. The English translation of Chinese food used to be ridiculous.


  Chen Lin, a professor at Beijing Foreign Studies University, is a core member of the translation team of "Olympic Menu", and he participated in the translation of "Olympic Menu" all the time. When he and his colleagues saw the ironic English translations of many Chinese dishes, they felt a heavy sense of mission while laughing.


  "The standardization of English translation of Chinese food began in 2006." Chen Lin said, "At that time, the Beijing Foreign Affairs Office and Tourism Bureau organized some old professors and started this work in cooperation with the translation room of the Ministry of Foreign Affairs. We collected more than 6,000 kinds of China dishes, then reduced them to more than 2,600 kinds, and finally determined more than 2,300 kinds for translation. " Experts who have been engaged in foreign language teaching and research for many years, such as Chen Lin, couldn’t help laughing after seeing the original English translations of these Chinese dishes.


  For example, "Mapo Tofu" is translated into "bean curd made by a pock-marked woman" (tofu made by a woman with freckles); "Husband and wife's lungslice" is translated into "hubband and wife’s lung slice"; "Broiler" is translated into "Chicken without sexual life" (chicken without sexual life), and these English translations are reported by the media as news.


  "There are many others. For example,’ Braised lion’s head’ is literally translated. Like’ husband and wife lung slices’, who dares to order such a dish from a foreigner who doesn’t know?" Chen Lin said with a smile, "To this end, we have formulated seven principles for the translation of dish names, including trying to keep the cultural color contained in the dish names, expressing the raw materials, tastes and practices of the dishes, trying to keep the commonly known names as agreed, trying to be concise and to the point, and then dealing with special situations." Now, the above Chinese dishes finally have an official name in English. MapoTofu is transliterated as Mapo Tofu, Broiler Chicken is literally translated as Steamed Spring Chicken, and Braised Pork Balls in SoySauce is translated as Braised Pork Balls according to raw materials and production methods. Similarly, "Husband and wife lung slices" is translated into "Beef and Ox Tripe in Chili Sauce" (beef and tripe in Chili sauce).


  Experts also argue in the process of translation.


  Since it is a translation, there is bound to be an argument. "This is normal." Chen Lin said, "For example, some people translate it into delicious pork meatballs, and some people translate it into sour and sweet meatballs. After discussion, we finally think that the later translation is more appropriate, so the English translation that appears on the menu is the pinyin of" Gollum Meat "in front and the taste" ‘Sweet and Sour Pork with Fat‘ "in the back. "Chen Lin said that all the people involved in the Chinese-English translation of this dish name are equal, and anyone’s opinion may be rejected. "For example, one translation of’ shredded pork with fish flavor’ is’ pork strips with fish flavor’, but some people suggest that’ fish flavor’ doesn’t seem to have a fixed taste, which makes sense. Although I agree with the above translation, I followed everyone’s meaning and finally translated this dish into’ pork strips with sweet and sour taste’."


  "The name of the dish can’t be too long. Our primary purpose is to let foreigners know the raw materials, tastes and practices. The China culture contained in the name of the dish can only be covered as much as possible. It is impossible to list long paragraphs on the menu to explain the origin of’ kung pao chicken’ or’ crossing the bridge rice noodles’. The spread of China culture and China food culture is indeed very important, but we hope that these will become the conversation materials at the dinner table. For example, through the introduction of tour guides, the mission of spreading food culture should be better. "


  Therefore, on the menu, all the dishes with the word Gong Bao are prefixed with "KungPao", and the most common translation is "practice+raw materials+taste", and special circumstances need special treatment. "For example,’ Buddha jumps over the wall’ can’t be translated directly, so you can only use Pinyin, and indicate the materials and practices, so that foreigners can understand it at a glance." Chen Lin said.


  The inexplicable translation of the name is more than the name of the dish.


  The translation of "Olympic Menu" has aroused great concern, not only in China media, but also in many foreign media. For example, the Washington Post published a full-page report on the Chinese-English translation of the "Olympic Menu" on the front page. They can’t help sighing that they won’t be puzzled by the strange names of dishes when they arrive in China. In fact, it is not just the English translation of Chinese food that puzzles foreigners.


  "Before translating the names of dishes, we have done many other translations, including signs and road signs in public places, and we have seen more jokes, such as’ Be careful of falling into the water’ being translated into’ falling into the water slowly’ and’ Don’t trample on the green land’ being translated into’ Greenland’, but this English word refers specifically to’ Greenland’." Chen Lin said.


  Chen Lin also used the words of foreign friends to emphasize the importance of standardizing the translation of dish names. Some foreign friends told Chen Lin that it is better not to change some existing translations. For them, these translations are very interesting. In this case, they can communicate with their friends. They even suggested that a related museum should be established.


  "When I was interviewed by foreign media, I said that there are historical reasons for this situation in China. Now, these efforts we have made for the Olympic Games are to provide convenience for them and also reflect the overall English level of our country, so it is very meaningful to do this work. " Chen Lin said.

How to deal with imported fruits when imported cherries are positive?

CCTV News:Following Wuxi, Jiangsu Province, cherries imported from a vegetable wholesale market in Shijiazhuang have also tested positive for nucleic acid recently. Shijiazhuang Municipal Market Supervision Administration issued the "Emergency Notice on Suspending Imported Fruits in the City". From January 24th, the food production and business operation units in Shijiazhuang suspended the purchase of imported fruits. The county market supervision and management bureaus carry out comprehensive investigations on the enterprises that store, process, produce and sell imported fruits within their respective jurisdictions, and all the imported fruits sold on shelves in the whole city shall be sealed off the shelves, and all the imported fruits in existing stocks shall be sealed on the spot.

Although Shijiazhuang officially announced on January 25th that after re-inspection of relevant products and personnel, the test results were all negative, and no COVID-19 virus was found. As soon as the news that many imported cherries were positive came out, many consumers were worried that imported cherries could still be eaten with confidence. What does it mean that its nucleic acid test is positive?

Wu Zunyou, chief epidemiologist of China CDC, said that nucleic acid positivity is not the same as infectivity: on the one hand, the temperature of preserved fruits is higher than that of frozen fish and other foods, and the virus has a short survival time at the temperature of preserved fruits; On the other hand, the nucleic acid test is positive, which may be a live virus or a dead virus or virus fragment, and it is not necessarily contagious. Wu Zunyou reminded that as long as you pay attention to hand hygiene and wash with running water before eating fruit, there should be no risk of infection.

Feng Zijian, deputy director of the China Center for Disease Control and Prevention, also said that positive detection does not mean infection with the virus. "It depends on the amount of pollution, and whether the polluted virus is active." Take Wuxi as an example. The imported cherries in Wuxi are positive for nucleic acid, and the virus load is very low, which will not cause too much infection risk to consumers. Feng Zijian said that people engaged in food processing or handling were infected before because they had been exposed to the virus for a long time and many times. For consumers, imported fruits generally do not cause infection, and they can be safely eaten after cleaning.

     Liang chen and Lu Jing, the sweet couple CP, have become the new wall of the audience. The love between them from the internet to reality has brought the sweetest candy in spring to countless audiences.

  Of course, this drama is more than just "sprinkling sugar". In the love relationship between liang chen and Lu Jing, the audience can see that the feelings are clean and pure. Under this emotional core, it also stands out in the "sister-brother relationship".

  At the end of the drama, Xu Mengjia, the screenwriter, accepted an exclusive interview with Sina Entertainment. In addition to sharing the creative process of the drama, she also responded to some questions raised by the audience.

  From network to reality, it takes a process.

  Sina Entertainment: Why did liang chen and Lu Jing fall in love online for so long? Many viewers are anxious to see their sweet interaction.

  Xu Mengjia: The first story tells that online dating comes into reality. Online dating is different from love in real life. It can quickly fall in love with a person at first sight. When online dating, Lu Jing didn’t know liang chen’s true identity, let alone his height, weight, age and appearance. Moreover, liang chen also turned on a voice changer, which will make Lu Jing even more uneasy. Another point is that Lu Jing and liang chen didn’t go for online dating at first.

  During the game, we let two people have feelings for each other, and then admit that they like him/her without knowing the identity of the other person, and they are willing to go to real life. This decision is not so easy to make, and it needs to be cautious, so it needs some emotional foreshadowing to reach the degree that the last two people are willing to go to the show.

  Sina Entertainment: In the process of playing games, how do two people’s emotions progress step by step?

  Xu Mengjia: When we first made the outline, we sorted out the emotional progressive relationship between the two people. First of all, we always think that the first five episodes of the game are very important. In the first game, it was Lu Jing who fully demonstrated his skills, and liang chen admired him very much. But at the same time, liang chen also fully demonstrated his own dishes, and Lu Jing was actually a little disgusted and depressed.

  By the second time, liang chen had already made him a human backpack and sent him bullets. This kind of behavior was actually touching for Lu Jing. At the same time, because he felt the admiration of liang chen, he also wanted to show off his skills. Unexpectedly, he overturned, and it would be a little fun for them to start playing again.

  When we arrived at the prison scene, we wanted to make an obvious progress in their feelings, so we emphasized that liang chen had some funny operations during his play, and liang chen was there to protect Lu Jing when he hung up. When Lu Jing came back, he asked liang chen why you didn’t run? Liang chen said that because we are going to die together, in this process, Lu Jing felt that the girl was very helpful. So I have changed a lot for her.

  Through these games, we let Lu Jing and liang chen feel the joy and fun of playing with each other, and at the same time let them see each other’s bright spots.

  Sina Entertainment: What are the considerations in the design of game scenes?

  Xu Mengjia: We changed the original PVP game into PVE, and changed the battle between players into a confrontation between people and robots. First, we kept the foundation of the gunfight game, followed by the collaboration between players, and the design of the copy of the game. If we just beat around in a map, it would be too boring, so we set different scenes for each copy, including the royal banquet hall, the prison and the ancient tomb jungle. In this case, it means that the audience can have a visual ice cream effect, and they can see that the hero and heroine have different costumes and different tasks in different scenes, and they will have a sense of freshness every time they are in the game mode.

  Sina Entertainment: In the previous plot, there were many coincidences between liang chen and Lu Jing, and netizens commented that it was "too routine". What do you think of such comments as a screenwriter?

  Xu Mengjia: I admit that this problem does exist, but there are actually objective reasons. First of all, the two of them are online dating. As I said before, there needs to be a process to warm up their feelings in the game. Two people don’t meet, but we are worried about them, because not meeting for a long time won’t do, so they also have some intersections in real life. In the process of writing, it’s impossible for them to really make any progress in real life, because they don’t know each other that you are the object of playing games with me every day, so everyone will think that there may be some drama in this part. Now I see the back and find that there is such a problem.

  There is no contrast between liang chen and Lu Jing, but they grow together.

  Sina Entertainment: Compared with Liang Chen, Lu Jing is a college student. Will the relationship between two people have a sense of disparity between feelings because of the disparity in status?

  Xu Mengjia: Although there is a certain gap temporarily, I think the two people are evenly matched. First of all, in her career, Liang Chen is certainly needless to say. She is a successful female star with many awards. However, although Lu Jing is a student, he has also won many awards, and he is still a good student. He is also the first Asian champion, and now he is still trying to participate in various competitions and big data competitions. Therefore, Lu Jing’s future is actually not lost to Liang Chen, which is in his career.

  Emotionally, I think these two people are independent personalities, and they don’t say that one party is completely obedient to the other. First of all, they all have clear plans for their own lives, their own careers and their own future. Two people belong to the common growth, even if there are problems, they will discuss with each other, run in with each other, and then reach an optimal and harmonious state, so I think the state of these two people is very equal and also a very good state.

  Sina Entertainment: Apart from the setting of two schoolmates, what is the uniqueness between Lu Jing and liang chen, which is different from the love between male and female protagonists in other plays?

  Xu Mengjia: First of all, they are different in identity. One is a student and the other is a singer. They are bound to encounter secular prejudice, for example, some people think that primary school students eat soft rice, etc. What we want to say is, don’t care too much and be too afraid of secular prejudice. Once you choose, you should pursue it bravely and fall in love bravely.

  There are two people together, liang chen and Lu Jing are actually problematic, but don’t give up easily. We should communicate well, run in with each other and grow together.

  Finally, don’t care too much about some external conditions. The essence of love is the attraction of the soul, so I think I hope that after watching it, the audience can stick to true love and don’t choose a relationship or enter a marriage just because it is suitable.

  Sina Entertainment: In the process of watching the drama, do you think that Lin Yi performed your imaginary landscape?

  Xu Mengjia: I think he is Lu Jing in my heart. He performed an unconventional schoolmaster. Lu Jing is very friendly to his roommate, the people around him, his neighbors and his friends. I think this is very similar to the feeling that Lin Yi himself gave me. Lu Jing is a very hard-working person, and I think Lin Yi is also a very serious person.

  In fact, in the preparatory stage, I have already discovered that he is a very serious actor I have ever seen. He will often attend script meetings with us and give opinions. For example, Lin Yi thinks that maybe the Lu Jing written in our script is sometimes too pretentious. Unlike a college student, he will advise us to accept it. I think what he said is very reasonable, so we try to make Lu Jing change him to be more grounded, more like a college student, and not too pretentious.

  We will talk with Lin Yi about his own understanding of Lu Jing. In the process of the actor’s own search and understanding of the role, Lin Yi did a very good job. The biggest surprise he gave me was actually kissing the scene. Lin Yi was really good at meeting relatives and acting very well.

  Sina Entertainment: What do you think is higher than the script in liang chen performed by LULU?

  Xu Mengjia: What surprises me about LULU is that her acting skills are very good. In the process of acting these romantic dramas, she will make me feel particularly substituted.

  In the process of performing this role, she will give us something that is not written in the script. For example, she has her own thoughts on the career development of this role. In fact, I think there are still some places that are not quite like a female star in our script. But through LULU’s performance, I think this is what I want to show a female star in her life. She actually makes up for some shortcomings in the script.

  Sina Entertainment: liang chen chose Lu Jing instead of Ding Jiayun. In the love between the year and the year, why are there more "love under the year" in recent years?

  Xu Mengjia: First of all, I think sister-in-law love is different from the traditional idol drama, which is generally a mode in which men are older than women. It is a quite new theme, and the audience doesn’t watch it very much. At the same time, I think it also reflects the rise of women’s consciousness in society. Now the audience doesn’t particularly like to see women’s roles attached to men.

  The audience’s ideas are similar to those we want to convey, that is, they strip off the external conditions of a man, such as his age, his income and his career. If you only look at him, his personality and his quality, will you still like him? What we want to convey is that you like his soul and his personality, not his external conditions. Under such circumstances,

  There is something wrong with the rhythm. We have tried to restore the famous scene.

  Sina Entertainment: How to convince the audience of the heroine’s identity background?

  Xu Mengjia: We didn’t package liang chen as a "big star". liang chen is just a popular female singer. As a singer, she is still a little different from the current star. But I think LULU has actually performed the feeling of being a popular singer.

  I think whether liang chen can become a popular singer depends on her own ability and strength, rather than focusing on things like hype and publicity. We want to shape her into an image that attaches great importance to her work and cares about her future career growth, and is also an image that dares to break through herself.

  LULU performed particularly well in this respect. In the 26th episode, she had a match with Liu Yiqing. At that time, liang chen insisted on singing "The First Dance in Winter", but Liu Yiqing just felt that we couldn’t do it for the time being. Can you put it down for the time being and get through this competition before making a breakthrough in the future? But LULU, she played with tears in her eyes at that time. Just say that you have been following the arrangement of the company for so many years, but you have never thought about my feelings. Why did you join this program? I came to this program just to break through myself, otherwise why did I come? When I saw this scene, I was actually particularly moved.

  Sina Entertainment: It’s almost the end of the show. Now let’s take a look at the creation of the whole drama. What do you think is the gain and loss of this drama?

  Xu Mengjia: First of all, the biggest feature of this drama is sweet and funny. I think we have done it in this respect. Whether it is the leading role or the supporting role, the image of the role is vivid and can be remembered by the audience. I think this is what we have done. There is also the famous scenes and lines of the original, and we have tried our best to restore them. There are some problems. First of all, there are still some problems in the rhythm. Everyone says that there are too many passes, which feels like a routine. We admit that there is indeed a problem. There is also my feeling that we paved the line between Sun Binyu and Mashanshan too late. In fact, their scenes should be mentioned in the male and female two, and more scenes should be given to them in the early stage, which is also a problem that we will try to avoid in future works.

The beauty industry has been bombarded: sunscreen spray causes white lungs, and hydrating products are all "IQ taxes"?

Image source: vision china

Blue whale financial reporter Wang Hanyi

"Sunscreen spray may lead to the risk of white lung. Can the relevant tips be implemented on every package?" "When will the hydration lie end?" "If there are problems with the test report and various lists, what can consumers believe?"

Recently, a video about "female R&D engineers after 1995 questioned experts at the skin care industry conference" attracted attention. At present, the specific identity of the woman in the video, the information of the industry conference she attended and who the industry experts she questioned are still unclear, but the three issues raised by the woman and some industry status reflected behind these issues are worth discussing.

Is it true that using sunscreen spray on the face causes pneumonia?

An emergency doctor who didn’t want to be named told Blue Whale Financial reporter that the ingredients in sunscreen spray are generally non-toxic to the body, but some sunscreen sprays do contain high-risk ingredients. "It is common for chemicals to cause skin allergies, and lung cancer is an example. If you hold your breath or cover your mouth and nose when using it, the spray will not have any adverse effects on your body."

In fact, some sunscreen sprays also have tips on how to use them correctly when selling. Blue Whale Financial reporter searched on the shopping platform with "sunscreen spray" as the key word, and randomly selected an adult spray and a child spray, both of which had relevant risk warnings or precautions such as "Do not inhale when using" and "Not recommended for people with respiratory diseases".

A research and development personnel in the front line of cosmetics production told Blue Whale Financial reporter: "At present, there is really no clear provision requiring sunscreen sprays to indicate the use method on the packaging, but many sunscreen sprays will be indicated on the details page or packaging."

Bai Yunhu, an expert in cosmetics industry management, said: "Whether it is necessary to mark some possible risk warnings on products, similar to the’ warning’ information marked on cigarettes by the tobacco industry, depends on industry norms and regulatory requirements. In most cases, CFDA (China Food and Drug Administration) has professional judgment, and if necessary, it will formulate relevant laws and regulations. For example, there are strict requirements for the identification of the sun protection index, and sun protection is also a special cosmetic, which needs to be filed separately. "

In addition, the reporter of Blue Whale Finance also interviewed consumers who would buy such products every day. Everyone said that it is common sense to avoid inhaling sunscreen spray, just like "inhaling smog and dust may cause pneumoconiosis". In fact, it’s not just sunscreen spray, but also the prickly heat powder used by children is risky to inhale.

Bing Han, the initiator of rational skin care and a doctor of dermatology at Tongji University, also said in his popular science article that sunscreen spray itself is safe, but it is unsafe to inhale sunscreen spray in respiratory tract. "It is very easy to use sunscreen spray correctly and avoid risks. I hope that everyone will not understand it as’ sunscreen spray causes pneumonia and must not be used.’ This is one-sided and wrong. "

It is worth noting that the sunscreen ingredients added in the sunscreen spray may be solid particles like titanium dioxide, and other soluble sunscreen ingredients such as emulsifiers and solvents may also cause lung damage after being inhaled into the respiratory tract. "Therefore, for the sake of consumer safety, especially for some careless consumers who are not very informed about it, the industry should really print the risk warning more prominently." Ice cold is called.

Is "hydrating" a lie?

The above-mentioned doctor said: "The general hydrating skin care products really can’t achieve the function of hydrating the skin. At most, it is to repair the stratum corneum when the skin is dry in autumn and winter, and human skin can maintain the balance of water and oil."

Although hydrating products can’t "replenish" water directly, they have certain soothing and moisturizing effects, which can increase the moisture content of users’ skin epidermis in a short time and reduce water loss, which is actually "hydrating" in the eyes of ordinary consumers.

Some industry veterans said, "There is important information hidden in the video, only saying that’ so-and-so hydration is invalid’. If the conclusion that the hydrating product is invalid is taken out of context. "

In fact, "hydrating" is just a conventional name, not all water enters the skin. Take the hydrating mask as an example, the patch mask has a function called hydration. To put it simply, the mask is attached to the face, which will soften the cuticle of the skin, that is, the skin is hydrated. "Skin hydration can accelerate the absorption of nutrients, like a kind of infrastructure. Therefore, I don’t recognize that hydrating is an IQ tax. " The above R&D personnel said.

After using the hydrating products, the water will still evaporate, and more importantly, how to retain the water. The "hydrating spray" on the market, take a bottle with you and spray it when your face is dry; Trying to absorb water by slapping hard is actually a misunderstanding of skin care caused by not understanding the principle of skin care. A more effective way is to take advantage of the short hydration time of the stratum corneum and use moisturizing products to retain water. Retaining water is what everyone often says about moisturizing and locking water. Skin care is a systematic project, and it can’t be a single efficacy theory.

Is the sunscreen effect test reliable?

Blue whale financial reporter learned that the standard method for testing sunscreen is human body test. In the test of SPF value and PA value, it is necessary to manually interpret the erythema and melanosis of skin.

For the human testing method of sunscreen, national standards are different. China, Japan, the United States, Australia and the European Union use the human testing method of at least 10 subjects for SPF testing. Among them, the EU standard is ISO24444;; Japanese standard is JCIA; of Japan Cosmetics Industry Association; China is the Technical Specification for Cosmetic Safety in 2015. Even if these standards are generally consistent, changes in details will affect the final test results, such as reference substance, smear area, irradiation measurement and so on.

This leads to that even if the results are tested according to the requirements, they will change because of the skin quality, race, state and even seasons of the subjects. Therefore, even if the same sunscreen product has different results in two human tests, it is normal.

In this regard, Bing Han believes: "The testing institution of sunscreen products is a designated institution, and its management is relatively strict. It must have CMA certification. From the recruitment of subjects, experiments and data statistics to the issuance of the final report, it must follow the norms, and the laboratory must regularly re-examine and parallel reference. It is not easy to obtain the inspection qualification of sunscreen products. Falsification will not only ruin your job, but also ruin your reputation. If I were the leader of a sunscreen testing institution, I wouldn’t take this risk. "

For the above viewpoints, what do the post-95 formulators think of the "rights fighter" in the video? The Blue Whale financial reporter contacted the blogger of the "skin care industry documentary for Lingfei" account, but as of press time, he has not received a reply yet.

According to the data of 36Kr Research Institute, the market size of precision skin care in China will be 48.8 billion yuan in 2022, and it is estimated that the market size will exceed 100 billion yuan in 2026, reaching 123.6 billion yuan. Consumers pay more and more attention to skin health and skin care, so they are more likely to be "anxious".

For consumers, they should learn more about relevant popular science knowledge and avoid being "kidnapped" by deliberate anxiety.

A gold medal carries all the hopes of a country.

Qianjiang evening news Hour Journalist Cao Linbo
At present, there are 26 countries with one gold medal in the gold medal list of Tokyo Olympic Games, and there are many gold medals among them. Only one gold medal bears all the expectations of this country and creates the history of this country.
The rugby sevens final of the 2020 Tokyo Olympic Games can be called the peak matchup. New Zealand is the triple world cup champion and Fiji is the double world cup champion. In the end, Fiji defeated New Zealand 27-12, successfully defending the champion of the project, and won the only gold medal for Fiji so far. New Zealand won the silver medal and Argentina won the bronze medal.
In fact, at the 2016 Rio Olympic Games, Fiji won the men’s rugby sevens championship. Before the Rio Olympic Games, Fiji participated in 14 Summer Olympic Games and 3 Winter Olympic Games, but it never got any medals.
In this Tokyo Olympic Games, they once again successfully defended their title with strong strength. In the men’s rugby sevens, Fiji is a top power. This stems from their strong popular base.
Since New Zealand and Britain brought this sport to Fiji in the late 19th century, rugby has gradually become the national sport here. Almost all the citizens are enthusiastic about it. Boys are proud to enter Fiji’s national echelons at all levels, and there are countless rugby clubs, large and small, in China. There are 890,000 people in China, with 80,000 registered rugby players, accounting for nearly 10%! It is no exaggeration to describe that all men, women and children in the country play rugby.
At the Tokyo Olympic Games, Fiji sent a delegation of 30 people: 12 of them participated in the men’s rugby sevens (and one reserve player) and 12 participated in the women’s rugby sevens.
However, there are many unknown stories behind this popular gold medal.
In April this year, Fiji ushered in the second wave of COVID-19 epidemic. In order to participate in the Tokyo Olympic Games, Fiji gave full support to the rugby team. The government quickly blocked the border and shut down all foreign-related flights.
In order to participate in the Olympic Games this time, all the Fiji team members were separated from their families and isolated at the designated place from the beginning of April. They even had to build a gym in the garage of the station to keep training, and then they were isolated in Australia and Japan. Fiji captain Jerry Tuwai said, "I miss my family so much that I almost want to skydive from the plane and go home to see them."
At the beginning of July, the Fiji team set out and boarded a cargo plane to transport frozen fish. After many hardships, they arrived in Tokyo to participate in the Olympic Games.
In the end, Fiji rugby team defended its title as expected. Although Fiji could not go to the streets as it did in the last Olympic Games because of the epidemic, they still lit fireworks and celebrated with the players from a distance.
Two days later, the Fiji women’s rugby sevens team also performed brilliantly in this Olympic Games. Although Fiji narrowly lost to New Zealand this time, it finally beat Britain to win the bronze medal, which has also created the best record of Fiji women’s rugby in the Olympic Games.
The presence of Bermuda’s delegation may be at most in the entrance ceremony of the opening ceremony of the Olympic Games. This country, which sounds quite mysterious, also achieved a breakthrough of zero gold medal in this Olympic Games.
In the women’s triathlon of the Tokyo Olympic Games, Duffy, an athlete from Bermuda, won the first gold medal in the Olympic history of the Bermuda delegation, and Bermuda became the smallest country in the Olympic history.
"This is a great moment, it’s incredible! I will be proud of this day for the rest of my life. Winning the first Olympic gold medal for Bermuda is of extraordinary significance far beyond my personal dream. " As one of the only two members of the Bermuda delegation, Duffy, who fought in the Olympic Games for four times, finally welcomed his dream.
In 2008, 21-year-old Duffy was a fledgling. At the Beijing Olympic Games, her bike broke down and she didn’t win the ranking. Duffy ranked 45th in the 2012 London Olympic Games; In the 2016 Rio Olympic Games, she won the eighth place in the individual Olympic Games, and she finally won the championship in this Olympic Games.
Since then, Bermuda, with an area of only 53 square kilometers and a population of only 63,000, has not only the legend of God and the Sunshine Coast, but also has its own place on the map of the Olympic history gold medal list. The last time a Bermuda athlete stood on the Olympic podium was 45 years ago. The male boxer Clarence Hill won a bronze medal at the 1976 Montreal Olympics.
Duffy is now Bermuda’s brightest tourist card. Open Bermuda’s official travel website, the first page is a photo of Duffy, which reads: Bermuda may not be a popular venue for triathlon. But Bermuda has produced a large number of iron athletes (both men and women)-including Olympic athlete Duffy, who brought home Bermuda’s first gold medal.
The Prime Minister of Bermuda sent her a congratulatory voice message. Even michael douglas, a famous Hollywood actress whose mother is from Bermuda, shouted congratulations to her on her social account.

People in Qinghai earthquake zone: No matter what kind of disaster we experience, we must live a good life.

Zhongxin. com Qinghai Minhe December 19 th Issue: People in Qinghai earthquake zone: No matter what kind of disaster we experience, we must live a good life.
Zhongxin. com reporter Li Jiangning Zhang Tianfu
On the afternoon of 19th, more than ten hours have passed since the Jishishan earthquake of magnitude 6.2 in Gansu. In front of a row of dumped houses in Zhaizi Village, guan ting zhen, Haidong City, Qinghai Province, women and children warmed up and chatted around charcoal fire. Not far away, several men set up tents, some carried stoves from home, and some moved bedding and other warm items …
It is night, and this is their "safe haven".
The picture shows villagers chatting around charcoal fire in Zhaizi Village, guan ting zhen, Haidong City, Qinghai Province. Hu Youjun
At 23: 59 on the 18th, an earthquake of magnitude 6.2 occurred in Jishishan County, Linxia Prefecture, Gansu Province. There are 22 towns and villages in Qinghai Province within 50 kilometers of the epicentre of this earthquake. The nearest towns and villages are Daofu Tibetan Township, guan ting zhen, Baizhuang Town and Zhongchuan Township.
"My wife and I were already asleep during the earthquake. After being awakened by the loud sound of the collapse of the house, my wife and I climbed out of the window of the house. Fortunately, neither of us was injured." Du Youwen is 60 years old. When the earthquake struck, almost all the houses in his home collapsed except one room where he slept.
The picture shows villagers building tents in Zhaizi Village, guan ting zhen, Haidong City, Qinghai Province. Hu Youjun
The Du family has lived in Zhaizi Village for generations, and there are currently 11 "Du families" living together. "This land was left by my grandfather’s grandfather. I have never experienced such a big earthquake. I was really scared at the time." Du Youwen seems to have calmed down a lot.
The reporter saw in Du Youwen’s home that the wall in the newly built house fell off in a large area, and the color TV and dining table were destroyed.
"After the earthquake, my son who was working in a foreign country called to ask about the situation, but at that time, my wife and I just ran out, and the mobile phone was still in the room. After I got the phone call back, my son and daughter-in-law cried on the other end of the phone." Du Youwen couldn’t help blushing.
"After the earthquake last night, 50 or 60 people in our family took bedding and firewood from home and ran to the mountain behind the village to take refuge." Du Fifty-six, a villager who also experienced the "night of fright", said, "It was very cold on the mountain at night, but at least we were lucky enough to get our lives, and this coldness was nothing."
Du Meiying, who talked about her new house in front of the charcoal fire, was the lucky one in this earthquake. "My house was newly built this summer, and it was built with the help of the government. It is very strong, and this earthquake has hardly been affected." Du Meiying said, "Although some houses in our village collapsed, everyone is fine. This is the best thing."
With the concerted efforts of Qi Xin, a simple and warm tent was quickly set up. "When the house collapses, it can be built again. It is the happiest thing for everyone to be together. No matter what kind of disaster we experience, we must live well! " Du Meiying, who survived the robbery, felt that there was nothing more important than living. (End)

Women in 2023 | Facing bravely and living positively is the way that every woman should pursue.

Cover journalist Chen Ganlu Xu Yingman Li Jiayu
In early winter in Chengdu, the ginkgo leaves are not completely yellow. The synchronized swimming world champions Jiang Wenwen and Jiang Tingting both appeared in Taikoo Li wearing thin jackets. After taking off their sneakers, putting on high heels and changing clothes, the two sisters made a group of fashion blockbusters. In the past year, studios, video studios, and various blockbusters going up and down the mountain were familiar with "daily life". Talking about the harvest and growth of this year, my sister Jiang Wenwen said: "We spent a lot of time in different fields this year, exploring things that we have never tried before, and actively feeling the challenges and happiness brought by different fields."
Promoting the Universiade and the Asian Games is the pride of China athletes.
The coming year 2023 is a "big year" for sports, and the summer Universiade in Chengdu comes as scheduled, which makes college students all over the world feel the charm of Chengdu. As Chengdu residents and ambassadors for the image promotion of Chengdu Universiade, Jiang Wenwen and Jiang Tingting have been very busy. "All kinds of promotion activities and public welfare activities have been busy." After the opening of the Chengdu Universiade, the sisters really felt the atmosphere when they were familiar with the stadium. "During the Universiade, we really felt the enthusiasm of our Chengdu people and the great changes brought by this event to our city."
In the autumn Asian Games in Hangzhou, the sisters also went to the scene. "The Asian Games actually have a complex for us. We started to let everyone know about the Asian Games in 2006, so the Asian Games is a very story-telling sports event for both of us." In the 2006 Doha Asian Games, Jiang Wenwen and Jiang Tingting, twin athletes, bloomed in the swimming pool, which shocked the synchronized swimming circle. It was also from Doha that they stepped onto the big stage of the World Championships, the World Cup and the Olympic Games. In the 2018 Asian Games in Jakarta, both of them were "upgraded" to their mothers’ two sisters who came back after giving birth, defeated the Japanese players in the double event, won the gold medal again after eight years, and won their sixth Asian Games gold medal.
Five years later, in Hangzhou, they became guests in the studio: "We watched many games, such as fencing and swimming, and then we also paid attention to the games of the older generation of athletes similar to us. It is also a rare learning process to communicate with them and share with athletes from different projects. "
The biggest emotion of the two major sports events is: "The two sports events were held in our motherland, and we are very proud to be athletes in China."
Youth volunteer service brings positive spirit to everyone.
Sharing on campus is no stranger to the two sisters. This year, as members of the Champion Volunteer Service Team, they entered the campus of Chengdu primary and secondary schools more frequently and participated in public welfare volunteer service. Not long ago, in the 44th track and field meeting of Chengdu No.7 Middle School, Jiang Wenwen shared the growth story and sports experience of the two sisters practicing flower swimming with all the teachers and students, and her sister Jiang Tingting lit the torch for the school sports meeting. Whether sharing or lighting the torch ceremony, the appearance of the two sisters made the children very excited. "I think that the athletes’ transformation to volunteer service is mainly through our own sportsmanship, growth experience, stories of setbacks and struggles to drive more teenagers and learn to grow through experience."
After retiring, the two sisters spent a lot of spare time on public welfare volunteer service. They are also directors of the Sichuan Youth Volunteers Association. "We just hope to use our positive spirit to lead and drive more young people to love sports and maintain an optimistic and positive attitude towards life."
As "Fengge women", Jiang Wenwen and Jiang Tingting are not absent from almost every session. "I think the activity of sealing women provides a very good platform for female friends, which gives us the opportunity to meet more outstanding female friends. I learn a lot from them through communication and sharing every year. "
In the new year, the two sisters actively embraced new changes and challenges and tried many new fields. "We spent a lot of time in different fields this year to explore things that we have never tried before and actively feel the challenges and happiness brought by different fields." This year, their "declaration of sealing the grid" has also gained new insights. My sister said: "Bravely facing a positive life state is a way of life that every woman must have and pursue." My sister said very tacitly, "I am the same. The only supplement is that I hope women can be more independent, have enough confidence in themselves and enjoy their own lifestyle and state independently."

When the ping-pong ball is hit at supersonic speed …

In animation, Japanese students usually have the power of conan the destroyer, and playing ball always feels like a high-tech war.
In reality, can humans play ball games so ferociously?
(All the articles are professional, please don’t imitate them at home.)
Although it is impossible to rely on manpower, we can use the power of air and machines, such as the "vacuum table tennis cannon."
A cannon is actually more like a pipe. When a cannon is fired, the speed of the accelerated table tennis can reach 450km/h, which is about one third of the speed of sound.
At this time, the table tennis directly crashed into the coke with air pressure, and this can was like a punch in the abdomen:
What if the speed of table tennis is increased to supersonic speed? Will it be more powerful? In fact, mythbusters, a well-known popular science team, made a similar attempt many years ago.
According to their test, the average adult can hit the ball at a speed of about 112.6 kilometers per hour after swinging.The speed of sound is 1224 kilometers per hour, which is an insurmountable gap.
Unless, of course, the table tennis player is a machine.
After several attempts, they successfully increased the speed of table tennis to 730 kilometers per hour by pressure jet, which directly penetrated the 2.5 cm cardboard, but this speed is still far from the speed of sound.
At this time, the "vacuum ping-pong cannon" appeared.
To put it simply, this device is to put a ping-pong ball at one end of a pipe and then seal both ends of the pipe:
Then, the air in the pipeline is drained to make it enter a vacuum state, and then the seal at one end is punctured, and the air will rush in wildly and then fill the vacuum space.
At this time, the table tennis in the middle will be pushed by the air and move to the other side at high speed, and there is no air obstacle on the road.
The power of this kind of vacuum cannon has been improved remarkably. With only a 1.8-meter-long pipe, the ejection speed of table tennis has reached 600 kilometers per hour.
And if we add a pressure chamber to the vacuum cannon and increase the length of the barrel, the speed will be upgraded again.
(Image from Purdue University of Technology)
But it is not as long as possible. Once the barrel was lengthened to 47 meters:
The acceleration effect is different. After firing, the human eye can’t see the ball moving at all, and the ball disappears directly:
However, when the table tennis flies out of the barrel, it has been squeezed out of the ball by resistance.
In the end, the barrel was reserved for 6 meters, which not only ensured the integrity of the ball, but also reached the speed of 1770 kilometers per hour, which properly exceeded the speed of sound.
So, "What destructive power will the vacuum table tennis cannon have now?The researchers set the shooting target-a thick pig elbow.
Fill in table tennis, adjust the pressure, pump out the air and fire!
Table tennis hit the surface of the pork completely, and the elbow suffered great damage. A round wound immediately appeared on the epidermis:
But the injury doesn’t stop there. Under this wound, there is a wound with a depth of nearly 4 cm:
However, this wave of injuries is difficult to subdivide how much table tennis can account for. After all, it broke at the moment it touched pork, and the subsequent injuries were more like air cannons.
But overall, it smells like animation.
There are still many people who use "table tennis vacuum cannons" to sabotage. They have chosen all kinds of strange targets for testing.
Mark French, a professor at Purdue Institute of Technology, and his students, combined a supersonic table tennis cannon with a pressure chamber and a vacuum gun, which is said to be faster than an F-16 fighter.
(All the articles are professional, please don’t imitate them at home.)
In the face of this kind of attack, the table tennis bat can do nothing at all and is directly penetrated:
When you hit a tape, it’s like hitting tofu:
Not only did the tape break a hole, but the carton at the back also broke a hole:
Carton:
The most cruel thing is to play a row of cans and disappear in an instant:
Look at the injury of cans, it should be destroyed by the group:
With such destructive power, it is no wonder that the professor emphasized on the whiteboard that he is a professional team and advised others not to try it at home.
Bruce Yeany, a physics teacher, also tried to play cans. From the effect point of view, he used more power:
But when he bombarded the watermelon, he encountered a problem, that is, the quality of table tennis was too small after all, and it broke directly in front of the watermelon:
Is this the only survivor in the table tennis test?
However, watermelon didn’t laugh for long. The teacher unhurriedly increased the weight of table tennis, not much, just filled it with water:
Now, watermelon immediately becomes watermelon juice:
Watermelon: Can’t you afford to play?
However, the most extravagant way to play table tennis vacuum cannon comes from anchors Dianna Cowern and Brandon.They aimed a cannon at an iPhone 11 Pro worth more than 6700 yuan:
How can I put it? The moment when table tennis hits the mobile phone is quite artistic. Maybe this is the happiness of being rich.
