  As an overseas brand SUV evergreen, Toyota RAV4 Rongfang’s main competitors include sister models Willanda, Honda CR-V and Volkswagen brand compact/medium-sized SUVs. But it has to be said that the competitiveness of Chinese brands in this market segment is also becoming stronger and stronger, especially new energy models have attracted many consumers, such as the Song PLUS, which starts at 154,800 yuan, can sell to 30,000 + per month. I believe there are many consumers who originally paid attention to RAV4 Rongfang.

● Editorial comments

  There are still many improvements in the product power of the RAV4 this time. There are new screens and updated intelligence systems, as well as electric seats and panoramic sunroof, etc., which are all in high demand from consumers. In the case of little price change, the cost performance of the new car has been improved, which will help RAV4 Rongfang maintain more sales. (Text/Autohome Chen Hao)

The female driver of the online ride-hailing car recorded 62 passengers in 4 months. The story is about to be published in a book (Photos)

Jiang Meixia organized the four passenger stories she recorded into a book and named it "Right Heart · Listening".

  Ms. Jiang took more than 200 rides for about four months and recorded the stories of 62 passengers, about 70,000 words. "Living in other people’s lives, truly feeling their joys and sorrows, switching between emotions, unable to help herself," she wrote at the end of the book. "Having such an experience is worth sobering up and satisfying."

  And behind her recording these stories is the mutual trust and tolerance between strangers.

  The 62 passengers covered all walks of life, of different ages and classes. Most of them started with the appearance of the passengers and the place where they got on the bus. Their stories could be described as strange.

  "No matter what everyone is going through, they are generally satisfied and have their own little happiness." Jiang Meixia said that she set the tone for herself from the beginning to record these "positive energy" things.

  After 120 days of online hailing and carrying more than 200 strangers, Jiang Meixia recorded the content and experiences of her chats with passengers in 60,000 to 70,000 words, bound into a book and titled "Right Heart · Listening". Just like Pu Songling, who set up a stall for tea in exchange for stories, in just four months, Jiang Meixia used online hailing to "break" into the lives of strangers in this city, and exchanged them for ordinary and touching stories. At present, she is still revising these stories, "hoping to find a suitable publisher to publish these stories."

  Hundreds are harvested every day

  But not RMB, but text

  "When I experience my own joys and troubles, I think from time to time. Are others as happy as I am? Are others as worried as I am? What kind of life are they living?" – From Right Heart · Listening

  Due to the need to take care of her daughter in the third year of high school, Jiang Meixia has no online car-booking now. A bound "book" is kept at home, full of the experience of driving and soliciting customers. In her words, "I get hundreds of dollars every day, but unfortunately it is not RMB, but some scattered words."

  Even though she is already a mother, Jiang Meixia still maintains a curious heart about new things. Last year, she signed up for a ride-hailing account. "I just want to experience it, not to make money, not to meet strangers, just to learn about new ways of getting around." During the four months from May to August last year, Jiang Meixia drove her Toyota SUV and started driving online hailing in the main urban area of Chengdu.

  Once near Taikoo Li, a male passenger "collapsed" in the passenger seat as soon as he got on the bus. "I was really depressed." The way the other party talked made Jiang Meixia unable to adapt for a while. "I also chatted with him naturally, like real-world friends who have known each other for a long time." She said that the man told her that he was a special ride on the Internet to chat with strangers. "This should be one of the first 10 passengers I pulled, and it is also the first time I met a passenger not to go somewhere, but to chat." Jiang Meixia said that this is the first time in her life that she has acted as a confidant sister for a stranger.

  "In fact, every passenger has their own thoughts that are inconvenient to share with their family and friends." Since then, Jiang Meixia, who has always liked to code, has the idea of deliberately digging into the stories of strangers around her. "I want to treat myself as a driver and break into their lives." After that, there are more notebooks and pens in her car, and she will record the interesting stories one by one and organize them when she gets home.

  By August last year, Jiang Meixia had run an online taxi for about four months. She received a rough count of more than 200 orders and recorded the stories of 62 passengers, about 70,000 words.

  The trust and tolerance of strangers

  Four months of feeling like living someone else’s life

  "Baby, don’t worry, it’s been a long time! Just like that, enjoy it casually, happily, and carefree, and grow up slowly." – From "Right Heart · Listening"

  After graduating from college, Jiang Meixia worked in sales for many years. "To do sales is to ask for people. Although customers change from unfamiliar to familiar, they have interests, so it is difficult to have such a simple and easy chat." Before that, Jiang Meixia believed that there was no trust and deep communication between strangers. "I take a taxi and never talk to my master." However, the experience of driving an online car-hailing made her feel that strangers can also chat like this – like friends, talk about work and life.

  "When I experience my own happiness and troubles, I think from time to time, are other people happy like me? Do other people have the same worries as me? What kind of life are they living?" This is the passage at the beginning of Jiang Meixia’s book. In four months, her passengers include elderly people in their late 80s, babies waiting to be fed, junior high school students, newcomers in the workplace, sweet couples, successful people… Different people tell different stories.

  At the end of the book, Ms. Jiang writes, "Living in other people’s lives, truly feeling their joys, sorrows and sorrows, switching between various emotions, and not being able to do it yourself. Having such an experience is worthy of sobriety and satisfaction."

  She said that the little happiness expressed by strangers moved her, and she had met people who were full of complaints due to the pressure of life, but everyone was looking forward. Behind the recording of these stories is the mutual trust and tolerance between strangers.

  Zhang Lan, a psychology expert, said that common topics are the basis for chatting with each other, and the enclosed moving space of the carriage creates such a chatting environment for passengers and drivers. "Everyone has the need to share and talk, but you may not find someone willing to listen in life. There is no interest relationship between strangers, they are psychologically equal, and there is no cost from the beginning to the end of the communication."

  This also explains why so many strangers are willing to take the initiative to chat with Jiang Meixia, allowing the online ride-hailing driver, who majored in Chinese and worked in sales in college, to have the opportunity to record the stories of unfamiliar passengers.

  62 passengers from all walks of life

  "Everyone has their own little happiness"

  "Living in other people’s lives, really feeling their joys and sorrows, switching between various emotions, and not being able to do it yourself. Having such an experience is worthy of sobriety and satisfaction." – From "Right Heart · Listening"

  Looking at Jiang Meixia’s book that tells the stories of unfamiliar passengers, the 62 passengers cover all walks of life, of different ages and classes. Most of them start with their appearance and boarding location, and their stories can be described in various ways.

  In the book, a primary school student told her that the study pressure was too great, and she had to go to the training class to make up lessons during the holiday, and she had to play the piano after making up lessons. Once, a 73-year-old lady got on the car, and few elderly people would use the software to call a car. Jiang Meixia praised a few words, and the cheerful old man said that if she had not had diabetes for more than 20 years, she would be in better spirits. Thinking that her mother had just been diagnosed with diabetes, Jiang Meixia paid attention to ask more questions. The old man very enthusiastically advised Jiang Meixia not to worry, and also recommended to her the medicine he had been taking.

  In the account, Jiang Meixia once again mentioned a male passenger who had been picked up in Taikoo Li. The other party said that he had started from scratch to invest millions to open three tea restaurants in the city center, and he was sitting in several luxury cars. He seemed to be a successful person in the eyes of his relatives and friends. But others did not know how tired he was. He rolled his sleeves and washed dishes when he was busy in business, couldn’t even pay the chef’s salary when he was in bad business, and his wife was unwell. The huge mental pressure made him unable to breathe, but he couldn’t tell his employees and friends that he "always had to stretch".

  "You and I don’t know each other, and the chance of meeting again is too small, so I won’t drive today, thank you for being my audience." Arriving at the destination, the man said, feeling better after complaining, and thanked Jiang Meixia apologetically.

  "No matter what everyone is going through, they are generally satisfied and have their own little happiness." Jiang Meixia said that she set the tone for herself from the beginning to record these "positive energy" things.

  In fact, it is not easy to chat with unfamiliar passengers every time. Jiang Meixia does not shy away from this point. She said that in fact, there are also some passengers who are very negative. She also recorded such passengers in her book: She once picked up a lady in Shiyangchang. After getting on the bus, the other party began to complain about her family and business. "Alas, business is too difficult now. The noodle shop became annoyed and couldn’t find a way to live in the clothing factory the day before yesterday. It’s so hard to make money!"

  She said that she tried her best to keep the passenger from being so depressed, but she seemed a little powerless. "Sometimes, people are infected by this negative emotion." But later, she thought that the passenger might feel better after complaining.

  Last September, because her daughter was in high school, Jiang Meixia stopped driving online taxis, and she began to organize the 62 passenger stories she had written down. She named the story and mood told by the passenger sitting on her right "Right Heart · Listening". In addition to the preface and postscript, the first chapter "Listening to the Wind" tells the little happiness of ordinary people, the second chapter "Slow and Long" records the cuteness and troubles from elementary school students to college students, and the third chapter "Practice" is the richest. It contains 32 stories, all of which are the mental journey of passengers in the workplace or with rich social experience.

  For now, she is still revising the stories, "hoping to find the right publisher to publish them."

  The passengers recorded by Jiang Meixia

  ● Hit the "flying" Lairong to eat the fly restaurant

  Received a call from Beijing. As soon as they got on the bus, two passengers, a man and a woman, discussed the twice-cooked pork and cold white meat for lunch, and smacked their tongues. "Are you here for business?" The female passenger rushed to answer: "We are here specifically for Chengdu cuisine. We don’t go to a single scenic spot, we find a place to eat every day, then go shopping, then eat again, go shopping and eat, hahahaha." The two who jokingly called the tour "foodie journey" laughed.

  I suggested that the two refer to the rankings of Dianping, but the male passenger said that he did not want to go to the big-name restaurants that are blooming everywhere, and he chose the small restaurants that the locals like to go to. The taste is authentic.

  ● Bad luck

  I made an appointment to pick him up at the entrance of Fuqin Community, and I saw a man in a gray jacket standing handsomely in the middle of the isolation pile, holding a small floral umbrella in one hand, looking at his mobile phone, and then looking at the direction of my car. Parking close to him, he quickly folded the umbrella, carefully placed the umbrella next to his right foot, and turned to me: "Go to He’s Orthopedic Hospital."

  "Oh, it’s raining too much, I can’t go out at all." The man looked at the continuous rain outside the window and sighed.

  "A few days ago, the newspaper also reported that an uncle sent two children to school and was washed into the river and disappeared. It’s terrible." The attentive man turned his head and said, "Drive slowly on rainy days.

  "Well, you can see little scrapers everywhere on the road these days." I smiled gratefully at him, "So don’t think I’m driving slowly."

  "How could it be? I am a person who has suffered a loss, and I will definitely not be too slow." The man saw my doubtful expression and patted his right arm wrapped in a jacket, "I am going to the orthopedic hospital to change my medicine. I got off work a little late one day last month. Because I live in Wenjiang, I wanted to go home quickly. I rode a battery car on the express lane at a speed of about 65 yards, but I was hung up by the taxi and broke my shoulder blade. Fortunately, the reflector of the taxi hung me down. If the car hit me directly, the consequences would be unimaginable."

  "However," the man changed the topic, "Thank God for giving me such a profound experience when I was young. At least, in the next few decades, I won’t have any accidents because of my’fast ‘. The so-called disaster and fortune depend on each other, I’m really grateful."

  ● Sales

  Driving in the direction of home, I received a list.

  A man and a woman got into the car with raindrops all over their faces, and the boy also opened the door of the car to let the girl get into the car first. After getting into the car, the two continued to talk enthusiastically. The girl’s tone was obviously dominant and dominant, and the boy seriously echoed

  Suddenly, I felt the girl lying on my driving chair, a little uncontrollable excitement: "Sister, how much is your car insurance? Did you buy it?"

  "The car insurance must have been bought long ago, and it hasn’t expired yet." I thought to myself, "Are you afraid that if I don’t buy insurance, I won’t be covered if there is a problem on the road?"

  "Sister, your drivers should have a group, right? You usually communicate there? Our company has an event where we can give you as much red wine as you buy insurance. For example, if you buy insurance for 5,000 yuan, our company will give you 5,000 yuan worth of red wine, which is very cost-effective."

  "Really? There’s such a good thing? Then how do you make money? You always have to make money, right?" To be honest, I was a little on guard.

  "Look, I just said, you have to ask how you make money." The boy saw the stitches and teased a little. Feeling that the girl rolled her eyes at the boy, the boy immediately became silent.

  "During the current promotion period, we mainly want to promote the brand of our red wine. When the popularity is established, we will naturally make money."

  "Sister, do you have a lot of WeChat? I’ll add your WeChat, and I’ll send you the information about the red wine."

  I haven’t had time to answer yet.

  "Sister, this is my business card. If the introducer comes over, call me and promise to give you a commission." The girl’s tone was unquestionable.

  (Due to layout reasons, it has been slightly deleted.)

Samsung admitted that the previous adjustment was wrong, and the Galaxy Note 20 series and S20 FE mobile phone updates are still monthly.

IT House reported on April 5 that Samsung Electronics recently adjusted its product update push plan to reduce the frequency of security updates for Galaxy S20 and Galaxy Note 20 series mobile phones, from monthly to quarterly (once every three months).

Galaxy S20, Galaxy S20+ and Galaxy S20 Ultra have been on the market for four years, so it is understandable to reduce the push frequency of security updates.

but Galaxy Note 20, Galaxy Note 20 Ultra and Galaxy S20 FE were released six months later than the above three models.Therefore, adjusting the push frequency has made many users feel puzzled and dissatisfied. The revised updated equipment list is attached to IT House as follows:

Samsung then updated its product page, saying it was a mistake.The update frequency of the above four models will continue to maintain the monthly rhythm and will get the security update in April.

Mistaking bald heads for football AI’s poor eyesight is not only due to less training.

  Ai growing pains

  Editor’s note In recent years, artificial intelligence has developed rapidly and its application fields have been expanding. However, at the same time, AI "rollover" cases are frequently searched. Based on this, this edition opens the column "AI Growing Pains" to focus on AI "rollover" events, analyze the phenomenon, analyze the reasons, explore the solutions, and look forward to its growth.

  Intern reporter Dai Xiaopei

  After the game, it is probably unprecedented for fans to ask referees to wear hats or wigs.

  At the end of October, Scottish fans experienced an "unforgettable" football match. In the Scottish Football Champions League match between Furness and Elven, the AI cameras on the sidelines turned a blind eye to whether the players passed the ball or attacked with the ball. Instead, they followed a linesman and took a close-up of "C position" from time to time. It turned out that the AI camera mistakenly identified the referee’s bald head as a football, so he chased the whole game crazily.

  Fans who watched the 90-minute game at home spent most of their time not watching the ball, but watching the bald heads. Many netizens joked that this game really "saw a loneliness".

  Why does the AI camera regard the bald head as a football? What do we need to do to prevent AI from making similar mistakes? Can you think that AI is "weak" when there is a "rollover" incident?

  Unconscious "provocation" from bald referees

  From direct participation in sports events to recording athletes’ performance, to live broadcast of competitions and analysis of athletes’ health status, AI is becoming the darling of the sports world. A few months ago, Barcelona Football Club (Barcelona) also joined hands with video technology company Pixellot to create an artificial intelligence coaching solution.

  Unexpectedly, AI, which has made great strides in sports, unexpectedly encountered an unconscious "provocation" from a bald linesman. Because the linesman’s bald head is too bright and the sun shines, the AI camera can’t tell which is the ball and which is the head. Previously, because the Furness team said that the AI tracking technology they used could clearly transmit the live images to the homes of every season ticket buyer, so that fans who could not go to the home due to the COVID-19 epidemic would not miss any game.

  It is reported that the camera used in the live broadcast of this competition is the multi-camera system provided by Pixellot, which cooperates with Barcelona. The system is powered by NVIDIA’s graphics processor (NVIDIA GPU), and the captured video resolution can reach 8K. These cameras can be installed in a fixed position without being manipulated by the camera operator. In order to capture the key moments, Pixellot collected hundreds of thousands of hours of sports videos to train its algorithm on the NVIDIA GPU of the local workstation.

  With a huge amount of available data, using deep learning algorithms and high-performance GPU computing blessing, it has three major driving forces to push AI forward. Why did Pixellot’s AI camera "roll over"?

  After the event, the relevant clubs and the technology companies that make cameras reflected. The problem seems very clear: the size and shape of football are similar to those of a human head, and the direct sunlight makes the AI camera fall into "confusion". I hope this will not happen again, because the Furness team responded that it knew the problem and will improve the next game to bring a better experience to the audience.

  Pixellot also said that it is not difficult to solve this problem. The existing target detection and tracking technology is mature. Pixellot didn’t consider the influence of bald head in the design stage, so it needs to collect some data of football and bald head to fine-tune the algorithm to eliminate the interference from bald head.

  Some technicians said that not only "this is a ball" data set, but also a "this is not a ball" data set is needed when training the AI camera of the live ball game. Bald head, bright white shoes, lighting, balls on the training ground next to the competition field and balls used by players to warm up are all interference factors that need to be considered when training AI.

  AI "poor eyesight" is the norm.

  Although the performance of AI cameras can be improved by increasing data "feeding", strengthening training and improving algorithms, some professionals believe that with the gradual expansion of AI application scenarios, such "rollover" incidents will exist for a long time.

  “AI‘ Rollover ’ It’s normal, no ‘ Rollover ’ It’s strange. " Professor eecs and Huang Tiejun, president of Beijing Zhiyuan Artificial Intelligence Research Institute, spoke frankly when interviewed by Science and Technology Daily reporter.

  Huang Tiejun believes that on the surface, the failure of the AI ? ? camera may be due to insufficient pre-training, but the main reason is that the current computer identification system is only trained with specific data. For example, in the above example, the neural network trained with a large number of football videos has surpassed humans in identifying football, but it ignores that this network is more sensitive to bald heads.

  It is common to recognize or "turn a blind eye" unknown objects at random.

  Machine vision is to endow the machine with visual perception, so that the machine has the scene perception ability similar to that of biological vision system, which involves optical imaging, image processing, analysis and recognition, execution and other components.

  "Take the camera as AI ‘ Eyes ’ In real scenes, there is still a long way to go for AI to recognize football and baldness like human eyes. " Huang Tiejun said.

  When can I finish this road and even realize that the eye of AI surpasses the human eye?

  It depends on when machine vision will bridge the gap with biological vision. "The brain in the skull senses the outside world in real time through more than 3 million nerve fibers, of which there are more than 1 million behind each eye." Huang Tiejun said, "The machine vision developed to this day is still a drop in the bucket compared with the biological vision system that took hundreds of millions of years to evolve."

  The human eye has strong adaptability, can identify targets in complex and changing environments, has advanced intelligence, and can use logical analysis and reasoning ability to identify changing targets and summarize laws. On the other hand, machine vision can use artificial intelligence neural network technology, but it can’t identify the changing target well. Due to the constraints of hardware conditions, the current general image acquisition system has poor color resolution.

  "Compared with biological visual neural networks, the visual neural networks of artificial intelligence are far apart in structure and scale, so their functions are much worse." Huang Tiejun said, "In real applications, machine vision ‘ Rollover ’ It is not an accident. It is only a case to identify the bald head as a football. Similar problems actually exist in large numbers. "

  Huang Tiejun said: "This time, the technology provider can make up for the loophole that the bald head mistakenly thinks of football, but there are still more loopholes. Deceiving the face recognition system with antagonistic picture training is only the tip of the iceberg."

  Different technical routes are racing.

  "Machine vision based on deep learning has made great progress in image recognition, but it has not really solved the perception problem." Huang Tiejun believes that deep learning is far from grasping the complexity of human visual system.

  Deep learning is based on the training of image and video big data, which is far from the biological vision that actively perceives the dynamic world, and it is still not out of demand for computing power. For example, if the video frame rate is increased from 30 to 30,000, the computing power of deep learning needs to be increased by 1,000 times.

  Biological neural network is a pulse neural network, which is more suitable for completing visual information processing. Huang Tiejun believes that learning from the neural network structure and information processing mechanism of biological vision system and establishing a new set of brain-like vision information processing theory and technology is the hope of restarting machine vision.

  Experts said that there are two main technical routes to develop artificial machine vision. One is to build a powerful intelligent system by collecting more data, increasing the amount of data and strengthening training; The second is to imitate the biological nervous system, follow the gourd painting gourd ladle, clarify the structure and even mechanism of the biological nervous system, and develop future intelligence on this basis.

  Huang Tiejun believes that the second path is more effective than the first one. "In a short time, the first one is easier to achieve results. But in the long run, it is more direct to start with biological neural networks and more confident to achieve the goal. "

  At present, most AI scholars support the first path, that is, to develop artificial intelligence including machine vision through "big data+big computing power". Huang Tiejun set foot on the road taken by a few people because he firmly believed that the biological visual neural network had great potential to be tapped. "Biological brain is the product of hundreds of millions of years of evolution, and it is the best transcendental structure. Powerful intelligence must rely on complex structures and stand on the shoulders of evolution. It seems difficult, but it is the fastest. "

  Turing, the "father of computer science", has long expressed his admiration for the biological brain. At the beginning of 1943, Shannon suggested that "cultural things" could be instilled in the electronic brain. Turing once retorted in public: "No, I’m not interested in building a powerful brain. What I want is just an ordinary brain, just like the head of the chairman of AT&T."

  Is developing machine vision, or artificial intelligence, starting from scratch, imitating biological neural networks, or is there another way? There is no conclusion yet. On different tracks, artificial intelligence is accelerating.

  Although there are many cases of AI "rollover", such as the practicability of Google AI eye disease diagnosis system is greatly reduced in Thailand, Tencent AI translation made a joke at the Boao Forum in 2018. But the AI era is accelerating and unstoppable.

  "It must be admitted that AI has indeed solved many practical problems, and it will gradually replace some functions of people. But we can’t exaggerate it too much. It is still far from our imaginary intelligence and needs more breakthroughs. " Huang Tiejun said that to keep an open mind and bridge the gap between "experimental simulation" and "real world", the development of AI technology has a long way to go.

Badminton is not popular in Europe and America? The answer is somewhat unexpected.

Xinhua News Agency, Suzhou, May 16th Question: Badminton is not popular in Europe and America? The answer is somewhat unexpected.

Xinhua News Agency reporters Ji Ye, Ding Wenxian, Wang Hengzhi and Xu Shihao

Badminton originated in Europe, but the athletic field has been "ruled" by Asian players for many years. At the Sudirman Cup World Badminton Mixed Team Championship in Suzhou in 2023, except for Denmark, which has the men’s singles Olympic champion Arceloró, other European and American teams still find it hard to win in the face of Asian powers.

Although there are occasional successes, most European and American players can only play a supporting role in badminton. Is this sport still popular in Europe and America? When the reporter threw this question to the European and American players participating in this competition, he got some unexpected answers.

"I feel that badminton is the first sport in France." The French women’s singles player Hugh’s answer surprised the reporter. The world’s No.55 player lost 0-2 to Japan’s Akane Yamaguchi in the women’s singles match in the group match on the 15th, and the French team also lost two games in a row in the group match, leaving early.

Although the national team has a poor record, Hugh said: "Many people in our country are playing badminton. Although the level is not high, the sport is widely carried out at the club level." She explained that due to media reports, commercial investment and other reasons, football is undoubtedly the largest sports industry in their country, but in terms of participation, badminton is the first sport in France.

England’s men’s doubles team Ryan/Wendy defeated South Korea in the 15th match, but England still lost to South Korea with a total score of 1:4, and they also lost two games in a row in Group D with France.

Ryan/Wendy and Hutt feel the same way. They said that in England, the public participation of badminton can rank second in all events. "More than 1 million people in Britain play badminton more than once a week, because it is easy to play badminton, as long as there is an open space."

However, they also said that according to the scale of the industry, badminton can only rank tenth in sports in England. Badminton is not regarded as a competitive sport in England, and people play badminton with an entertaining attitude. Moreover, badminton can’t make professional players make a lot of money, and most young people will still choose sports with mature industries such as football. Badminton events are not highly exposed here, and football matches are shown on TV every week.

On the competitive level, Danish badminton has the strongest overall strength in Europe, with the emergence of the current president of the World Badminton Federation and Olympic champion Larsson, Gade, one of the "four kings" of badminton, and Ansailong, a gold medalist in the Olympic and World Championships. In 2016, the Danish team also won the Thomas Cup, which represents the highest honor of the world badminton men’s team for the first time. This is the first time that the Thomas Cup has been won by a team outside Asia.

With the approach of the Paris Olympic Games, France has begun to "have ideas" in sports. Rivas, the coach who trained Marin, the women’s singles champion of Rio Olympic Games, was invited to be the coach of the French team. France has also set up a support institution named "National Institute of Sports, Profession and Performance" for the national team, and is equipped with experts in psychology, nutrition and medicine. The coaching team can analyze according to all kinds of data and information to help athletes train individually.

In Rivas’ view, the French team will gradually become a strong force in European badminton, and will launch an impact on the Danish team in the future. To become a world power, it needs long-term planning and perseverance. "The goal of French badminton in the future is to become the top five or seven in the world."

Compared with the above countries and regions, the popularity of badminton in Germany is not very high. Fabian, a German men’s singles player who participated in this competition, told reporters that badminton is a minority sport in Germany. Few people play badminton in schools, and the media attention is relatively low. In Australia, Canada and other places, the development of badminton still depends on the efforts of Chinese players.
