The original Hu Ge’s private character was made public, and a certain eighteen-line actor was interviewed, revealing the poignant inside story of the entertainment industry

With the increasing popularity of various group auditions, more and more young people want to enter the entertainment industry, but often the dream is beautiful, but the reality is cruel. These so-called artists usually only bloom for a moment, and after the big hit, they will cool down, because if you want to develop for a long time, you need to have excellent works to support. Otherwise, it will be difficult to maintain the popularity, so there are not a few young artists who have been brushed off.

Recently, a famous media specifically interviewed an unknown young artist, and this artist also revealed many rules of the entertainment industry. He claimed that since the "Idol Trainee" program became popular, he also had certain ideas.

As time went by, during a walk-on, he met a senior with deeper experience, and was fortunate enough to be taken to dinner with the boss. However, during the meal, a leader bluntly said that he had no money or resources, and no one would accompany him to play and support him.

Although it didn’t sound good, this sentence was quite realistic. But he didn’t give up, but still signed up for the audition. After that, some brokerage companies took the initiative to come to the door, and guaranteed that he would definitely get a place after signing the contract, and the brokerage company would also pack him into an image of an amateur, taking the route of sad-fishing to gain sympathy, saying that someone would definitely pay for it.

Finally, he couldn’t resist the soft grinding and hard bubble of the brokerage company, and he agreed. But after agreeing, the nightmare really began. The brokerage company asked him for money in various names, adding up to more than 80,000 yuan. At this time, he naively thought that 80,000 yuan could buy a promotion quota, which was not a loss. But in fact, he was brushed off in the first round, and the brokerage company at this time only had one sentence: Your skills are not good, go back and practice again, and you will be guaranteed to pass next year.

It was only later that he learned that there were many people who didn’t show any signs of becoming famous even after many years of training, and at the same time, they also wasted their youth in these years. At this time, he realized that such a program was operated with capital, and ordinary people could be said to have no hope at all. Therefore, he later spent a large sum of money to terminate the contract with the company and continued to start a walk-on life.

It is worth mentioning that the artist also specifically mentioned Hu Ge during the interview. He said that although he is just an actor, he has also met many celebrities, and the only one who does not have the air of a star is Hu Ge. Not only does he not have the so-called celebrity arrogance, but he also often chats with them, sharpens their acting skills and gives them encouragement, etc. This seems to be the first time in history that a group performance has evaluated Hu Ge’s character.

And through an interview with this unknown artist, we can find that the water in the entertainment industry is actually very deep, and it is not something that an ordinary person with no background can easily step into. Therefore, without a certain level of strength, not everyone can enter.

The above is the entire content of this issue. I don’t know what readers think about this matter? Welcome to leave a message and comment with a lot of support. See you next time.

Long press like to have a surprise~

Beidou-3 Final Star was successfully launched! The meeting point reveals the way forward for Beidou

  Intersection news, with the successful launch of the Beidou-3 GEO-3 satellite, our country’s Beidou satellite navigation system construction project has been successfully completed, the star array has been listed, and the global "Skynet" has been successfully woven. What changes will the "Beidou-3" bring to our lives in the future? After more than 30 years of practice and exploration, why is our country so persistent in the construction of the "Beidou" system? The reporter interviewed Professor Wen Xin and Professor Kang Guohua from the School of Aeronautics and Astronautics of Nanjing University of Aeronautics and Astronautics to explore the way forward for Beidou together.

  You’ve already used Beidou, but you may not know it.

  Many people know that our country launched the Beidou satellite, but they do not know that Beidou has long been available to the people and open to the world.

  If you pay attention, it is not difficult to find that your smartphone can always accurately tell the time, almost not like a watch, occasionally "going fast" or "going slow", and it is the Beidou satellite navigation system that helps you "check the watch".

  Kang Guohua, a professor at the School of Astronautics at Nanjing University of Aeronautics and Astronautics, told reporters that "Beidou" is not just a satellite launched into the sky, but a huge system project. Seemingly out of reach, it is actually closely related to our lives. "Since the 1980s, the whole world has been using the GPS of the United States. With the Beidou system, the absolute dominance of GPS in the field of global satellite positioning has been challenged, and now most of our mobile phones have begun to use the Beidou navigation system."

  He took out his mobile phone and showed the reporter the satellite zenith map displayed by the mobile APP. The picture shows the movement of the satellites of the four major satellite navigation systems in the world on the local zenith. They are the Global Navigation and Positioning System (GPS) of the United States, the GLONASS system of Russia, the Galileo system of the European Union, and the Beidou system of China. "Among them, the color satellites that can receive signals are in orbit, while the black and white ones are temporarily unable to receive signals."

  Each Beidou satellite weighs 850KG, has a payload weight of 300Kg, and carries three functions – positioning, timing and short message. Positioning is the foundation of navigation, and navigation is the application of positioning, Kang Guohua said. Positioning is "telling you where you are" and navigation is "telling you how to go from where you are now to where you want to go."

  Timing, as the name implies, is to "give the exact time". For some instruments and equipment, it is to calibrate the time. As long as the Beidou timing function is used, even if it is distributed in different parts of the world, the time can still be "synchronized". Kang Guohua told reporters that time synchronization is a national security guarantee, such as high-speed rail, power grid, computer network communication, etc., all need time synchronization. For example, relying on the precise positioning of Beidou, the high-speed rail brakes from 350 kilometers per hour to parking, and the final stop error can be controlled within 10 centimeters.

  Short messages are a unique feature of China’s Beidou. Unlike GPS receivers, which can only receive satellite signals in one direction, Beidou receivers can not only achieve positioning, but also send and receive text messages similar to mobile phones, and transmit two-way text messages through satellites.

  During the Wenchuan earthquake rescue in 2008, the ground communication facilities were seriously damaged and even paralyzed. The rescue troops used Beidou short messages to send the first message from the disaster area, accurately reporting the disaster situation and the location of the disaster to the disaster relief and rescue headquarters, which played a huge role. At that time, the accuracy of "Beidou No. 1" was actually not high enough. Its two-way communication function had shown great power and saved countless lives.

  "The stars move", and a "Skynet" has been woven for more than 20 years.

  Behind the dream of "Big Dipper" is the relay struggle of several generations, from nothing to something, from weak to strong, the "Big Dipper" star is increasingly dazzling.

  Professor Wen Xin of the School of Aeronautics and Astronautics of Nanjing University of Aeronautics and Astronautics told reporters that people’s ideas about the Beidou satellite navigation system can be traced back to 1983. Academician Chen Fangyun, a famous aerospace expert, first proposed the concept and idea of dual satellite positioning.

  "The chief designer who set a three-step development plan for the Beidou satellite navigation system is Sun Jiadong, the father of our country’s’two bombs and one star ‘." Wen Xin introduced that in 1994 our country launched the construction of the Beidou satellite navigation test system, which is the "Beidou generation". The second step was to start the construction of the Beidou satellite navigation system in 2004. In 2012, a regional passive service capacity was formed. And the third step was this year, the formation of a global passive service capacity. "From 2007 to 2010, a network of satellites was launched continuously, weaving an information network in the sky."

  Since the "Beidou Generation" uses a dual-star positioning method, the "Beidou Generation" has a lot of room for improvement in positioning accuracy, timing accuracy, service area, etc., especially the problem of large signal transmission delay. "For example, the positioning accuracy of the" Beidou Generation "is 20 meters, which means that the" Beidou Generation "cannot" see "two objects less than 20 meters away from the distant space and calculate their position difference.

  Kang Guohua said that at present, our mobile phones are generally integrated with satellite systems from two, three or even four countries. "Why don’t we use China’s Beidou system alone? Because the Beidou-2 system focuses on the Asia-Pacific region, the service in other parts of the world is not very stable."

  Kang Guohua compared the multiple launches of Beidou satellites to "puzzles". Beidou-1 is an experimental satellite, with only four satellites, which are only over our country and have all been decommissioned. Later, Beidou-2 is a regional networking satellite, covering a total of 20 satellites in the Asia-Pacific region. The space segment of the "Beidou-3" satellite navigation system consists of 27 medium-earth orbit satellites, 5 synchronous orbit satellites, and 3 inclined synchronous orbit satellites, totaling 35 satellites.

  From the first satellite of Beidou-2, our country has launched 54 Beidou navigation satellites, which have been officially put into the network since June. The last network satellite launched on June 23 is the 55th in the entire Beidou satellite navigation system.

  Kang Guohua said that although this time we launched the last star in the puzzle, in fact, the satellites in the Beidou system have been changing. "Each satellite has a lifespan, and it needs to be retired in an average of 8-10 years. Since the construction of the third generation of Beidou, many satellites have been retired and added. The significance of the 55th star is to make the Beidou system truly the Beidou of the world, and it can be located anywhere on earth."

  The brightest Chinese star, let the stars in the sky "refer to the Big Dipper"

  What is the significance of the Chinese astronauts’ dedication to the "Beidou" satellite?

  As an important weapon of the country, Beidou is a major space infrastructure in our country. The goal of building our country’s space-time reference network and navigation information network is an important support for my great power status and strategic interests. "It can be said that the sooner the construction is made, the more strategic advantage it will have." Kang Guohua gave an example. "Satellite positioning requires the transmission of radio waves at specific frequency points from the sky to the ground. Since only specific frequency points have the least attenuation during the process of electromagnetic waves penetrating the atmosphere, these frequency points have become important strategic resources." According to the current ITU’s "first-served" rule for frequency point allocation, the United States has chosen the best frequency band because it was the first to build GPS.

  The competition in satellite navigation is not only the competition of the technical system, but also the competition of constellations and signals. China, Europe, and the United States have gone through years of coordination work on satellite frequency and orbital position issues, and even "open and secret wars", which are full of "games" of aerospace powers.

  The Beidou-2 navigation system has experienced such a pressing time. According to the relevant regulations of the ITU, the Beidou-2 navigation system must complete the satellite navigation signal in orbit and broadcast to the ground within seven years. Otherwise, the priority right to use the navigation frequency will be cancelled. It is necessary to reapply for the frequency and carry out relevant international coordination. As a result, our country will lose the best opportunity to develop a global satellite navigation system.

  Facing the urgent development task, Chen Zhonggui, an alumnus of Nanjing University of Aeronautics and Astronautics and then the deputy chief designer of the Beidou-2 satellite, led the party commando team to improve the integrated test verification method, and fought for 8 months with "5 + 2" a week and "white + black" every day. On April 16, 2007, two days after the successful launch, Beijing received a clear signal from the flight test satellite. At this time, there were less than 4 hours left before the space frequency failure – it was this feat that effectively protected the frequency resources of our country’s satellite navigation system and opened the prelude to the construction of the Beidou regional navigation system.

  "Today, the successful networking of the Beidou-3 global satellite navigation system marks that our country has the" capital "of PK with the strength of the US GPS navigation system in the field of satellite navigation systems. Beidou is not only a national project, but also a national project. ‘Beidou’ has multiple’firsts’." Wen Xin listed that the Beidou satellite navigation system has adopted the hybrid constellation system of three orbits (GEO, IGSO, MEO) for the first time; it has reached the requirement of 100% localization of components for the first time; and it has proposed cooperation and compatibility for the first time… These all make China’s aerospace and satellite monitoring technology more confident in the world.

  For example, the on-board atomic clock, which is the "heart" of a navigation satellite, was once a technological blank in China. There was a time difference between radio wave transmission and reception, and the time difference multiplied by the speed of light was the distance. As long as the error was one second, the distance would be 300,000 kilometers. During the development of Beidou-2, a Swiss company was introduced, but later the European Union required the company to provide atomic clocks that were an order of magnitude less accurate than the "Galileo" navigation system, which made Chen Zhonggui and the design team more deeply realize that "key core technologies cannot be bought, or they cannot be bought, or they cannot be bought."

  Today, our country has conquered the key technologies of rubidium atomic clock and hydrogen atomic clock, and used these two atomic clocks on the Beidou navigation satellite to achieve the establishment of time benchmarks. Among them, the on-board rubidium atomic clock has achieved 100% localization of components, and the current accuracy can reach 3 million The error is only 1 second, and the passive on-board hydrogen atomic clock has an error of 1 second in 10 million years.

  At present, the Beidou-3 satellite has formed a distinct Beidou feature in terms of positioning services, wide-area enhancement services, global short message services, search and rescue services, etc., and has achieved partial leadership in foreign technology in terms of system signal performance, system transmission and ranging performance, on-board atomic clock performance, and localization of key products and components. In the open class on ideological and political affairs of Nanjing University of Aeronautics and Astronautics, Chen Zhonggui confidently pointed out that "the core of the Beidou-3 system is to serve the world with higher accuracy and higher performance," so that China’s Beidou is also the world’s Beidou! "

  The era of "Beidou +" has begun, and it must be easy to use both in the sky and on the ground

  After the Beidou global network, the speed of integrating the Beidou system with positioning, timing and short message services into the lives of ordinary people will accelerate. "Beidou +" life will come faster.

  "It will become an infrastructure like the water grid and the power grid, and daily life can no longer be separated from it. If you order a takeaway or order a ride-hailing car, you need to use satellite positioning to determine your current location." Kang Guohua said, but then Beidou has to solve various problems such as reliability, accuracy and stability.

  "Beidou’s biggest problem now is application promotion." Kang Guohua said that after all, GPS has been developed more than 20 years earlier than us, and users have become sticky and inertial. Take mobile phones as an example, replacing GPS chips with Beidou chips will increase a lot of external costs, and merchants have no incentive to replace them. Therefore, in some mature areas of GPS applications, replacing Beidou often encounters relatively large resistance. But the more people use Beidou, the lower the cost will be, and the faster the iterative improvement speed will be, forming positive feedback.

  The research on "low-orbit satellite navigation enhancement" currently led by Professor Kang Guohua is related to the promotion and application of Beidou. "If we compare the Beidou system to a highway-like backbone network, it can provide positioning accuracy better than 10 meters; then our work is similar to building’provincial roads’, and further improve the accuracy on the basis of this backbone network."

  As an example, Kang Guohua said that when you shuttle between city buildings, due to the "canyon" effect formed by the buildings, you can see the sky is very small, so the signal received by the satellite is small and weak. The low-orbit navigation enhancement system is to add another layer of low-orbit constellation below the Beidou constellation, and use the navigation enhancement system on the low-orbit satellite to achieve Beidou signal enhancement and broadcasting, thereby improving the strength of the signal and upgrading the original Beidou road-level positioning to lane-level positioning. Before we could know where people were, now I have to know whether you took your left foot or your right foot. "Kang Guohua said. Now Japan has a Quasi-Zenith satellite that does something similar, but they do it with GPS, and our team did it with our own Beidou.

  In the future, the Beidou satellite navigation system will have a wide range of applications in land, sea, aerospace, mass consumption and other fields. "For example, in marine fisheries, the navigation of ships and the establishment of an integrated fishery information service network are inseparable from the positioning signal of the Beidou system." Wen Xin said that in the field of transportation, the application of advanced satellite navigation technology is an important means to realize the informatization and modernization of transportation, and is of great significance to the establishment of a smooth, efficient, safe and green modern transportation system. "

  The reporter learned that the Beidou system has begun to be applied in many fields in our country. For example, the hydrological monitoring system based on the Beidou system has realized the real-time transmission of hydrological and water regime information, greatly improving the accuracy of rain, water regime, drought and disaster information collection and the timeliness of transmission. It has been widely used in southern Shaanxi, the Yangtze River Basin and the Yellow River Basin in our country, and the number of users has reached more than 4,000. "In the field of weather forecasting, after many years of meteorological digital message transmission application experiments, a series of meteorological forecast-type Beidou end point equipment and system application solutions developed by scientific researchers have solved the automatic transmission and collection of weather station digital messages and the visual display function of weather station map distribution by the National Meteorological Administration and meteorological centers in various cities. At present, the end point of Beidou application in the meteorological field has reached thousands of units. "

  Microlink – "Beidou No. 3" Chief Engineer "Nanhangzao"

  "Beidou-3" also has a cordial connection with Jiangsu. Its chief designer, Chen Zhonggui, is an 86-level alumnus of Nanjing University of Aeronautics and Astronautics.

  "Look up at the starry sky, hold up the ambition to explore the universe. Work hard to realize the dream of a space power." On this year’s fifth "China Space Day" and the 50th anniversary of the successful launch of the "Dongfanghong No. 1" satellite, Chen Zhonggui sent an affectionate message to the students of his alma mater.

  Chen Zhonggui has worked in the Aerospace Academy for 31 years after graduation, of which 20 years have been engaged in work related to Beidou. Beidou satellite navigation system has grown from nothing, from weak to strong, from regional to global, he has witnessed 80,000 Beidou people working day and night, painstaking research and dedication.

  In December 2018, Chen Zhonggui returned to the campus of China Southern Airlines and brought a shocking open class on the ideology and politics of the alumni chief teacher "Beidou Navigation Satellite" to the students. Chen Zhonggui, who originally studied mining machinery as an undergraduate, quit his job after working for a few years out of yearning for his aerospace dream and chose to apply for the mathematical mechanics major of Nanjing Institute of Aeronautics and Astronautics (the predecessor of Nanjing University of Aeronautics and Astronautics), under the tutelage of Professor Zhu Ming, who is engaged in multi-body dynamics research.

  "The study style of China Southern Airlines is very strict, especially the requirements of the professional basic courses are particularly high, and the exams are not ambiguous." This is what Chen Zhonggui remembered most when he was studying in graduate school. He still remembers the automatic control of this course, "The exam results are not satisfactory, and the teacher will talk to the students to help the students analyze the reasons, and draw inferences from one another." It is with such a rigorous study style and dedicated professional teachers that Chen Zhonggui made up for the gap in professional foundation in time during his graduate school, laying the foundation for the later work development.

  Under the guidance of Mr. Zhu Ming, Chen Zhonggui aimed his graduate thesis at the new modeling theory of multi-body dynamics and the development of analytical software. During the writing of his graduate thesis, he had more opportunities to come into contact with the field of aerospace, and at that time, aerospace was most lacking in professionals engaged in basic disciplines such as dynamics and heat. It was this opportunity that Chen Zhonggui "naturally" formed a tacit connection with aerospace, and after graduation, he resolutely chose the Fifth Academy of Aerospace, a field he had pursued and loved.

  In the open class for the students of China Southern Airlines, Chen Zhonggui comprehensively reviewed the development process of our country’s Beidou satellite navigation from No. 1 to No. 3, and systematically described the technical evolution and major innovation achievements of our country in the field of satellite navigation systems. Now the Beidou satellite navigation system has achieved 100% localization of stand-alone products that make up satellites, and all core components have been localized. It has become the fourth mature satellite navigation system after the US GPS, the Russian GLONASS system, and the European Galileo system.

  Compared with Beidou-2, Beidou-3 requires more complete functions, more indicators, and higher reliability. How to achieve a leap in system performance in a short period of time is a severe challenge for the Beidou-3 demonstration team. Chen Zhonggui led the development team to check the data, build the standard, build the model, make the layout, and compile the plan, and finally formed a technical demonstration report that meets the different needs of all parties.

  Looking to the future, he hopes to build a Beidou satellite navigation system that serves the world, is focused, distinctive, locally leading, and has a smooth transition, forming a more ubiquitous, more integrated, and more intelligent benchmark space-time system. Making China’s Beidou also the Beidou of the world is his unswerving career goal for satellite navigation, and it is also a solemn oath to our country’s aerospace power.

You have to take it easy to exercise. Too much force is easy to hurt your kidneys.

  Facing the haunting Covid-19, more and more people realize that they must take the initiative to improve their immunity. Exercise and fitness is undoubtedly one of the most popular choices. In addition to keeping fit, from shining vest line, touching navel with backhand, to drying A4 waist, showing body has also become the driving force of fitness people’s efforts. However, although exercise is good, don’t use too much force, otherwise it is easy to accidentally hurt the kidney.

  The real case tells you that excessive fitness "brings trouble" to the kidney.

  Women are sent to the rescue room for squats. "Squats" is a common means to test their physical fitness, and it is not uncommon for them to go to the hospital because of excessive squats. Miss Yang participated in the company’s outward bound training. She usually didn’t do much exercise, but in order to perform well, she did hundreds of squats in one breath, which surprised her teammates and opponents. However, for this honor, Miss Yang also paid a painful price. On the second day after exercise, she felt sore all over, and her urine color was like strong tea. She was rushed to the hospital by her family. Emergency tests found that the creatine kinase in her body exceeded the normal value by more than 1,000 times, and rhabdomyolysis was diagnosed and rescued.

  Push-ups for boys with renal failure Push-ups are the most common exercise to exercise physical strength and endurance, and people do push-ups when they disagree. Mr. Chen, 23, and several friends PK push-ups, initially agreed to do 80, but the result was not a winner, "continue to compare." Fifteen minutes later, the big guys were defeated one after another, leaving only Mr. Chen to stick to the end. At that time, Mr. Chen only felt a little sore in his arm. The next night, his body began to ache, his arm was difficult to lift, and his urine became darker. Because of his busy work, he didn’t pay attention to it. On the fifth day, Mr. Chen found that the symptoms became more and more serious, his whole body was sore and weak, and his urine was like soy sauce. After being taken to the hospital by ambulance, the doctor found that his kidney function had been damaged.

  The above two cases belong to non-traumatic fatigue rhabdomyolysis caused by excessive exercise, which refers to a group of clinical syndromes that all kinds of excessive exercise lead to skeletal muscle injury, myolysis and destruction, and skeletal muscle cell contents (such as enzymes, potassium, phosphorus, creatinine and myoglobin) are released into the blood circulation. In severe cases, it is often complicated with acute renal failure and even multiple organ dysfunction.

  These symptoms indicate that the amount of exercise exceeds the standard.

  Rhabdomyolysis is characterized by muscle involvement such as limb pain, tenderness, swelling and weakness after a large number of exercises, as well as inflammatory reactions such as fever, general fatigue and increased proportion of white blood cells and neutrophils. Judging from the appearance of the patient’s urine, it is brown or soy sauce-colored urine. About 30% of this disease will have acute kidney injury. When the kidney injury is serious, oliguria, urine and other azotemia’s manifestations can be seen.

  Therefore, it is recommended that you rest for more than 24 hours after a lot of exercise, but your muscles are getting sore and tired, and your urine is getting darker and darker. You must go to the hospital immediately. Acute renal failure is likely to result from the continuous progress of the disease. Acute renal failure caused by excessive exercise, most of them can recover completely if they go to the hospital in time. If they see a doctor without urine, it will be too late, and the damaged renal function may be irreversible.

  How to judge excessive exercise and what are the signs of rhabdomyolysis?

  Symptom 1: After normal exercise, it is mild muscle soreness, and pressing muscles will not cause pain. If you have obvious muscle pain, soreness and tenderness after exercise, you must be vigilant.

  Symptom 2: After normal exercise, people will become refreshed, while excessive exercise will make people weak and tired.

  Symptom 3: Normal urine is clear and slightly yellow in color. If urine is like strong tea and soy sauce, you need to be alert to rhabdomyolysis.

  Remember these five points to guard against sports injury "kidney"

  In the process of daily fitness and exercise, we can prevent kidney injury by grasping the following five points:

  1. Exercise should be gradual, which requires proper warm-up. Intense exercise and sudden exercise after a long period of inactivity are the most likely to cause injuries.

  2. Exercise according to your ability. There is no obvious discomfort such as fatigue, shortness of breath and chest tightness after the exercise. On the contrary, it means that you exercise too much.

  3. Protect the digestive system. Attention should be paid to protecting the gastrointestinal tract when exercising at night, and the interval between exercise time and meal time should be at least one hour. After exercise, it is not appropriate to drink plenty of water immediately, and the method of "drinking less for many times" should be adopted.

  4. Manage chronic diseases. The trend of rejuvenation of chronic diseases is becoming more and more serious. Many young friends are busy with their work and don’t pay enough attention to their own physical condition. Patients with chronic nephritis, hypertension and diabetes need to review their tests regularly and formulate their own exercise methods according to the test results.

  5. Pay attention to balanced nutrition. The way of nutritional supplement after exercise varies from person to person, and patients with chronic diseases such as hypertension, diabetes, liver disease and kidney disease can’t take a lot of protein powder.

16 ways to play badminton well

First, for amateur badminton lovers, if they want to improve their skills in a short time, some practical methods can be adopted. Here we recommend a 16-rule rule to you.

1, strive to hit the ball in front of the upper body, don’t let the ball fall to the height below the neck, otherwise the return ball will have no attack.

2. Hold your hands and clap your hands as relaxed as possible so as to maximize the strength of your wrist.

3. In singles, you should return to the center position immediately after each stroke. When defending doubles, you should return to the position parallel to your partner, while when attacking doubles, you should keep the position before and after your partner. When serving doubles, you should immediately block the net forward after serving a short ball to prevent your opponent from hitting a short ball back.

4, in singles, unless spiking, never hit the ball in the opponent’s midfield, try to play two corners.

5. When making a powerful forehand or backhand stroke, the body should turn to the hitting side in order to stand firm.

6. The singles serve should be as high and far as possible, the doubles serve should be short, the flight route of the ball should be close to the upper edge of the net, and the serve should be changeable.

7. Try to confuse each other with fake actions as much as possible within the scope permitted by the rules, but don’t reveal your intentions in advance.

8. When playing a high ball, it is necessary to accurately judge the flying direction of the ball, and the ball should be played as high as possible and close to the opponent’s bottom line.

9. When hanging the ball in front of the net, the route of the ball should be short and as close as possible to the net.

10. Spike should be as far away from the opponent as possible or directly hit the opponent’s grip or shoulder.

11. When you are at a loss or need a short respite, you can hit a high ball and then return to the center of the field.

12. For beginners, the backhand end line is usually its weak area, and attention should be paid to hitting its weakness.

13. When hitting the high ball back in the frontcourt, you should try to use spike, which is an important scoring method, but don’t hit the high and short ball at the baseline, which usually gives the opponent a chance to kill the ball.

14. Many athletes have their own unique style of play, so they should be good at judging the landing point of the ball and get into the appropriate position in time, but don’t expose their movements too early.

15. When you receive the service in doubles, you should lift the racket to force the opponent to serve low. If the opponent’s service is too high, you should immediately go forward and kill.

16. If you are scoring, don’t change your style of play. If you are losing, you should immediately adjust your manners. If your continuous attack doesn’t work, you can hit a high ball and then find a fighter to attack again.

Second, the six key decisions to win in singles

1. Forcing backhand

As far as all athletes are concerned, the backhand stroke in the backcourt is always more or less weaker than the forehand stroke, which is relatively less offensive and the ball path is relatively simple (due to the limitation of physiological anatomy). Some athletes can’t hit the ball to the opponent’s end line with backhand in the backcourt, so they should attack the opponent’s backhand without relaxation.

(1) adjust the position of the other party

Make the opponent’s backhand area open, and then hit the ball to the backhand area, forcing the opponent to use the backhand to hit the ball.

(2) For opponents with poor backhand.

People with poor backhand in the backcourt often use overhead hitting, sideways hitting and sideways bowing to make up for the lack of backhand. Because the backhand area is hit overhead and sideways, the body center of gravity and body position should be biased to the sideline of the left field, so you can repeatedly attack the opponent’s backhand area to keep his body away from the center. In this way, there is a large gap in the forehand area, which is originally the advantage of the other side, and it has become the target of attack. When the opponent hits a half-court lob, the choice of the smash point should be: if the opponent moves slowly, the smash point should be until he just left. Because it is very difficult to stop immediately and then turn around to catch the ball in the fast movement. When forcing the opponent to hit the ball with a backhand in the backcourt, he should take the initiative to move forward and seal the front of the net. When the opponent hangs the ball in front of the net with a backhand in the backcourt, he can quickly come forward to kill or rub and hook, creating an active opportunity for the next shot.

2. Flat high ball presses the bottom line

Hit the two corners of the opponent’s backcourt with a fast and accurate flat ball, try to reduce the flying arc of the ball as much as possible on the premise that the opponent can’t intercept it, and press the opponent to the bottom line. When the opponent returns the half-court high ball, he can smash the attack. When using the flat high ball to press the baseline, the tactical effect of the flat high ball can be increased if it is combined with chopping and killing. Under normal circumstances, the more the landing point of the flat ball and the landing point of the kill and hoist are pulled apart, the better the effect will be.

3, pull, hanging combination to kill the ball

This tactic is to hit the ball to the four corners of the opponent’s court accurately, so that the opponent will run back and forth on the court every time he hits the ball. When using this tactic, different methods of pulling and hanging should be adopted for opponents with different characteristics. For those who have slow backward footwork, they can play more front and back fields; For those who run blindly and fly all over the field, you can use the double ball and fake action; For those with poor flexibility, you should make more diagonal lines and try to make the other side turn around as much as possible; Those with poor backhand in the backcourt still attack backhand by pulling away; Those who are not good at physical strength can use more slapping and hanging to consume their physical strength, and then overcome it. If you can skillfully use the techniques of flat ball, split hanging and rubbing, pushing and hooking in front of the net, you can quickly pull away the opponent and wait for an opportunity to smash, then this tactic can get better results.

4. Hanging and killing the Internet

First, in the backcourt, the ball should be pressed down with light kill, point kill and split kill combined with hanging ball, and the landing point should be chosen on both sides of the field to make the opponent passively return the ball. When the opponent returns the ball in front of the net, he quickly goes online to create a half-court smash opportunity by rubbing the ball against the net, or crossing the diagonal, or pushing it quickly; If the opponent picks a high ball in front of the net, he can kill the ball directly on him in the process of retreating.

5. Transition ball

First of all, it should be clear that the transition ball is to get rid of passivity and actively create conditions for the counterattack of the next shot. How to change passivity into initiative is an important part of the competition. When you are passive, do it: first, buy time to adjust yourself and control the center of gravity of your body. It is a common means to hit a high ball from the baseline in front of the net or in the backcourt. When you are in the state of running and chasing the ball, or when your body’s center of gravity is out of control, you can play a high-distance ball to gain time, restore your body’s center of gravity and adjust your situation. Secondly, use the change of the ball path to disrupt the opponent’s offensive steps. When catching a kill ball or a lob, you should return the ball to a place far away from the opponent, so as to destroy the continuous rapid attack of the opponent’s lob and lob. If the opponent hangs and kills the ball and blindly goes online, but his own goal is better, he can return the ball to the opponent’s bottom line.

6, defensive counterattack

This tactic is to deal with opponents who attack blindly and have poor physical strength. At the beginning of the game, first lure the opponent to attack with a high ball, and when the opponent only cares about attacking and neglects his own defense, he can attack suddenly. Or attack when the opponent’s physical strength drops and the speed slows down. This tactic of starting to stick to it, taking advantage of it, waiting for it, and making a preemptive strike sometimes works well.

Third, the midfield batting technique-practice

Midcourt batting techniques can be roughly divided into: blocking the net before the ball, picking the high ball, drawing the ball and hitting the ball quickly.

1, blocking the net before the ball technology

1) Forehand block straight net ball technology

This technique is mostly used to catch the ball from the other side. Before catching the ball, use the footwork of catching and killing the ball to move to the sideline of the right field, with the body leaning to the right, the arm extending to the right, the forearm rotating outwards and the wrist abduction. When hitting the ball, the forearm rotates slightly and turns the wrist to drive the racket to push the ball from the bottom right to the front, and block the ball to the front of the straight net. When hitting the ball, the forearm can be rotated from the outside to the inside to drive the racket to cut and block the straight net from the right to the front. After hitting the ball, turn left to face the net, then step forward with your right foot, and the racket turns left with your body and closes in front of you.

2) The forehand block is the same as the technical preparation posture of the diagonal net.

When hitting the ball with a swing, the forearm is slightly rotated inward while the elbow joint is flexed, and the wrist is extended from the back to the right side of the adduction flashing bat holder. Before hitting the ball on the right side, the wrist and fingers control the angle of the racket face to make the ball fall in front of the diagonal net.

3) backhand blocking the ball in front of the straight net

The forehand is also used to catch and kill the ball. First, use the footwork of catching and killing the ball to move to the sideline of the left field, turn left and lean forward, with the right shoulder facing the net, bend the right elbow, abduct the wrist, and lead the racket to the front of the left shoulder. When hitting the ball, with the impulse of the opponent’s incoming ball, the front arm drives the racket from the upper left to the left, and the top force of the thumb is used to swing the ball lightly to stop the ball back to the front of the straight net. After hitting the ball, the body turns right to face the net, and the racket moves in front of the body.

4) The backhand hook is used to kick the ball in front of the diagonal net

The backhand hook is used to catch the kill ball diagonally. When hitting the ball, the wrist flicks the lower left side of the ball holder from abduction to backward extension, making the ball fall in front of the diagonal net.

2, the lob technique

1) The forehand catches and picks the straight backcourt golf ball

When the opponent kills the right line ball, his right foot takes a big step to the right. Move the racket sideways with footwork, swing the right arm slightly to the right and then slightly outward, with the wrist extended to the maximum, so that the racket swings back quickly, followed by a slight outward swing when the right forearm swings forward rapidly, and the wrist extends from the back to the straight wrist. At this time, the elbow plays the role of "fulcrum", and the racket face accurately hits the ball at the middle and lower parts of the bat tray, making the ball fly in a straight and high direction. After hitting the ball, the forearm is rotated inward, the racket is waved to the front of the body, and the racket is recovered to the front.

2) Backcourt lob with backhand catch.

Before hitting the ball, the forearm is pronated, the wrist is abduction, and the racquet is brought to the left. When hitting the ball, the upper arm is supported, the forearm swings rapidly to the right front, the wrist flashes from abduction to backward extension, the racket is gripped tightly, and with the jacking force of the thumb, the ball is swung at full speed to make it fly in a straight line. If you swing diagonally, the ball flies diagonally.

3. Ball-drawing technique

1) Forehand flat draw

Stand with your feet equal and slightly wider than your shoulders, and take a small step to the right with your right foot. At the same time, your upper body leans slightly to the right, and your right arm swings up to the right. With the racket lifted up, your elbow joint keeps a certain angle. Before hitting the ball, your elbow joint swings forward, your forearm is slightly rotated back, and your wrist is slightly abduction and extension, leading to the back of your body.

When hitting the ball, the forearm rotates inward, the wrist is straight and flashing, the fingers grasp the handle, and the racket sweeps the ball from right back to right front at high speed. After hitting the ball, the racket will swing to the left, and the left foot will follow further to the left, ready to meet the second ball.

2) backhand flat draw

The right foot crosses in front of the left side, the center of gravity is on the left foot, and the backhand grip of the right hand is in front of the left side. Before hitting the ball, the elbow is slightly raised, the forearm is pronated, the wrist is abduction, and the racquet is taken to the left. When hitting the ball, driven by the right turn of the hip, the forearm rotates outward, the wrist flashes from abduction to straightness, and the bottom of the ball holder is swung. After hitting the ball, the racket is retracted to the right side with the back movement of the body.

4, quick play technology

1) Fast forehand play

Feet apart, right foot slightly in front, left foot in back, knees in a semi-squat position, hold the racket in front, lift the racket, lift it over the top of your head, and lead it to the lower right side behind your head, so the grip is loose. When it is judged that the incoming ball is above the head, the body moves forward slightly, and at the same time, the left foot takes a small step forward, and the right foot is slightly straightened into a left lunge, and the hitting point is selected in front of the right shoulder. Lift the upper arm forward and upward, bend the elbow, swing the forearm with external rotation later, and pat it behind the head. When hitting the ball, the forearm is forward, and the wrist is extended from backward to forward, and the back of the bat tray is flashed, so that the ball flies straight and quickly to the vicinity of the opponent’s midfield area. After hitting the ball, the racket moves forward to the left with the front cover and the right foot, and stands slightly behind the center line. The racket is raised from the lower left back to the upper front, ready to meet the next incoming ball.

2) backhand fast play

Stand in the left field with your feet parallel, with your center of gravity on your right foot, and lift your racket in front of the right side. When it is judged that the ball is in the left field, the right forearm swings to the left, the body turns to the right shoulder to the net slightly to the left, and the left foot also takes a small step to the left. The forearm is rotated internally, and the wrist abduction is taken behind the left side. When hitting the ball, the forearm is rotated outward, the wrist is straight and flashing, and the fingers suddenly grasp the handle, and the front cover holds the back of the ball, so that the ball flies straight forward. After hitting the ball, the racket is raised from the lower right to the upper front to prepare for the next shot.

 

Fourth, the response of singles attack tactics

1, serve and attack tactics of strain.

Serving and attacking is an important scoring method in the game, and serving can be based on the opponent’s position. In order to gain the initiative of the first few shots, we should use different service methods according to the habit of hitting the ball back, counterattack ability, playing characteristics, spirit and psychological state. Through the use of this tactic, the whole strategic deployment of the other side is disrupted, causing the other side to be caught off guard. Especially at the critical moment, different effects can be achieved by using the tactics of serving and attacking; We can use it to open the deadlock and strive for initiative when we are deadlocked. When leading, you can use it to pursue victory and beat your opponent at one go; When you are behind, you can use it to make the final struggle, turn the tide and turn defeat into victory.

(1) Pre-attack tactics

Serve the ball in the frontcourt, serve the ball in the No.1 area, serve the ball in the area between No.1 and No.2 area, and serve the chasing ball.

The main purpose of serving the ball in the frontcourt is to restrict the opponent from attacking immediately, and the other purpose is to pass the accuracy. Consciously judge the opponent’s return ball path, so as to organize and launch a quick and powerful attack, achieve direct score or get a second attack opportunity. Under normal circumstances, the ball in the forecourt area should be served mainly between the No.1 and No.2 areas and the chasing ball, which is safer and will not cause mistakes.

 (2) Serve the high ball and take the attack tactics.

There are three kinds of flat lobs: No.3 zone, No.4 zone and between No.3 and No.4 zones.

The difference between the tactics of serving a high ball and the tactics of attacking in the front court is that the attacking in the front court can directly seize the fighter plane to attack, while the attacking in the front court can only get the opportunity to attack by defending the middle.

The purpose of leveling the high ball: first, to cooperate with the ball attack in the forecourt; The second is to let the opponent attack blindly or within the scope of our judgment, so that the server can quickly turn from defense to attack; The third is to cause the other party to make a direct mistake because of losing control.

(3) The flat shot is mainly the flat shot in Zone 3.

The purpose of flat shooting tactics is: first, to sneak attack, if the opponent’s reaction is slow, or the position is off the sideline, and the gap in Zone 3 is large, the success rate of sneaking into Zone 3 may be high; The second is to force the other side to play flat and fast; The third is to force the opponent to the backcourt and cause the gap in the front area of the net.

 2. The response of the tactics of receiving serve and attacking.

Receiving and attacking tactics is the easiest to score in receiving and serving tactics. One of the most threatening tactics. However, the premise is that the quality of the opponent’s service is not good. If the landing point is not in place when serving the high ball; Too high when the ball crosses the net in the forecourt; The speed of flat shot is not fast and the angle is not good; Poor rhythm, landing point and radian when serving a flat high ball will create opportunities for receiving and attacking.

Without this prerequisite, blindly rushing to attack will have a poor effect and a low success rate. In addition, there must be positive. Bold sense of rushing to attack. In order to get the success (score) of the attack tactics, we must also combine our own technical characteristics and physical conditions with each other’s technical characteristics. Physical condition and psychological quality. For example, when the opponent serves a flat high ball from the right court with poor landing point, which has caused us an excellent opportunity to launch a rush attack, we should use our best skills, seize the opponent’s weakness, and make a decisive and bold rush attack.

The completion of the attack tactics mostly depends on the organization of two or three beats to attack the ball path. Therefore, once the attack is launched, it is necessary to speed up, expand the control surface, seize each other’s weaknesses or customary routes and attack to the end, and complete the attack tactics in one go.

1-1! Premier League exciting World War I: firmino scored a 90-minute draw, and Liverpool forced their lives to continue.

Entering the sprint stage of the season, Liverpool, which fought on one track, finally ushered in a wave of seven-game winning streak, forcibly retaining the hope of the Premier League for four. This weekend, the 37th round of Premier League started, Liverpool played against Villa at home, and klopp scored 3 points, which continued to put pressure on Manchester United and Newcastle. However, no one expected that Liverpool almost overturned. With firmino’s 98th minute draw, they narrowly saved one point and a chance to compete for the fourth place.

In the Premier League standings, Liverpool ranked fifth with 65 points in 36 games, while Villa ranked eighth with 57 points in 36 games. Although this is Milner, firmino, Keita and Chamberlain’s home farewell battle, considering the importance of the fourth round, Uncle Zha sent all the main teams, with Salah, Jiakebo and Luis Diaz leading the front trident.

In the 22nd minute, Villa kicked a quick counterattack, Watkins took the ball into the penalty area, konate put it down from behind, and the referee whistled for a penalty. Watkins personally took the penalty, and as a result, he hit the bottom line and Liverpool escaped.

Just when he thought that there would be a blessing for Liverpool’s survival, Villa took the lead in breaking the deadlock: in the 27th minute, Douglas Lewis made a 45-degree cross to the back, konate took the lead, Jacob Ramsey dived to the top and scored, and alysson was beyond his reach, 1-0!

In the 40th minute, Villa won a free kick in the frontcourt, Douglas-Louis suddenly passed directly, Jacob-Ramsey threw off Robertson, and the small-angle volley was blocked by alysson.

In the 45th minute, there was a huge controversy on the court. Mince kicked Jiakebo, and at the prompt of VAR, the referee only showed a yellow card.

Throughout the first half of the game, Villa scored a goal with three shots and two shots, which was extremely efficient and Liverpool was in a desperate situation.

In the 55th minute, Arnold sent a cross to the back, and Luis Diaz’s header ferry was blocked. Fan Dike used his quick wits and knocked back at the baseline for the first time. konate followed the shooting and was blocked by Villa players on the goal line. Gakpo got the ball again and volleyed into the net in the melee. However, VAR indicated that Fan Dike was offside first, and Liverpool were happy.

Klopp really couldn’t sit still because he couldn’t equalize the score. In the 72nd minute, three players were replaced in a row, and firmino and Milner came off the bench to stage a farewell game at home, and Luis Diaz and Robertson were removed.

This substitution received a miraculous effect. In the 90th minute, Salah sent an outside instep cross, and firmino grabbed the goal to help Liverpool equalize the score.

Firmino gave a perfect farewell at home and continued his life for Liverpool. After this game, Manchester United and Newcastle scored 69 points in 36 games, while Liverpool scored 66 points in 37 games. There is still a glimmer of hope because Liverpool’s goal difference is dominant.

In the final round, Liverpool’s opponent is Southampton, the vice squad leader. They need to score all three points, and then wait for Manchester United or Newcastle to make mistakes before they can qualify for the Champions League.

Create another ChatGPT? The founder of OpenAI said to open the interface and create killer applications.

OpenAI also wants to build another "killer" application similar to ChatGPT.

On March 9th, local time, Reuters reported that Sam Altman, founder and CEO of OpenAI, said at the Morgan Stanley conference that the company would focus on building a platform, opening API interfaces to developers and creating "killer apps" like ChatGPT.

At present, the popularity of ChatGPT is high. Internet analyst Similarweb said that since its launch in November last year, the popularity of ChatGPT has soared, and the number of visits to the website has increased from 616 million in January this year to over 1 billion now.

With the rising popularity, the company not only launched the paid service ChatGPT Plus to individual users, but also began to seek cooperation with enterprises. Altman said that OpenAI is working with corporate customers to train models in specific areas in order to effectively reduce the number of errors in AI (Artificial Intelligence) systems.

He mentioned that companies working with OpenAI can use the company’s data and make copies of models to reduce data security problems. For example, he said that Bain & Company, a management consulting company, cooperated with OpenAI to provide personalized advertising copy and images for companies such as Coca-Cola by using its ChatGPT and DALL-E platforms.

In addition, Altman added that individual users should have more control over the way AI (Artificial Intelligence) works. The company said last month that it was upgrading the chat bot to allow users to customize it to solve the error of artificial intelligence. He said, "We will soon introduce more things to give users more control over the system so that it can act in different ways."

Altman also admitted that the accuracy of the current AI system cannot reach 100%, but he predicted that applications such as AI doctors and AI lawyers would soon appear on mobile phones.

In fact, OpenAI announced on March 1st that it had introduced API and allowed any enterprise to build ChatGPT technology in their own applications, websites, products and services. Snap, Quizlet, Instacart and Shopify were early adopters of ChatGPT API.

According to public information, API is an application programming interface, which can realize the communication between computer software. Through API interface, developers can develop applications without accessing source code or understanding the details of internal working mechanism. Amazon’s official website gives an example-the software system of the Meteorological Bureau includes daily weather data, and the weather application on the user’s mobile phone "talks" with the system through the API, and displays the latest weather information every day on the mobile phone.

Previously, Greg Brockman, president and chairman of OpenAI, said that ChatGPT API is supported by GPT-3.5-turbo, a natural language model, in which "turbo" represents an optimized version of GPT-3.5, with faster response speed. This model adopts homologous technology with the popular ChatGPT, which is based on the enhanced version of GPT-3.

TechCrunch, an American technology media, said that the initial motivation of OpenAI to develop GPT-3.5-turbo may be to reduce the computing cost of ChatGPT. Altman once said on Twitter that the cost of ChatGPT’s dialogue with users is "amazing", and each conversation needs to cost a few cents or more.

It is worth noting that a new generation of natural language processing model GPT-4 will be launched next week. On March 9, local time, Andreas Braun, chief technology officer of Microsoft Germany, mentioned in an AI (Artificial Intelligence) activity, "We will launch GPT-4 next week, which will be a multimodal models that can provide completely different possibilities, such as supporting video."

In addition, on March 16th, Microsoft will hold an online activity of "Artificial Intelligence Leading Future Work" to showcase Microsoft’s latest AI technology and discuss the application and development of artificial intelligence in work scenarios.
