Football enters the era of big data. China sports should practice the basic skills of the new era.

　　Football enters the era of big data (Dazhao Review)

　　Three days ago, Shandong Luneng Taishan professional football club management information system based on big data entered a new stage of version 3.0, and once again took the lead in football management concepts and innovations in the new era.

　　Since 2015, Shandong Luneng Taishan Club has extensively learned from the research results in the field of global football big data, and continuously improved the level of data mining, analysis and application. Through more than two years of efforts, it has established an information management system including 10 modules including teams, players, competitions, training, medical care and public opinion.

　　At the same time, China Football Association has also made plans for the construction of information management system and accelerated its implementation. This is an important measure to change the backward appearance of football in China and meet the needs of the public for football development.

　　Today’s society has entered the era of knowledge economy with information technology as the core, and informatization has become a booster to promote national economic and social development. To improve the overall level of football and sports in China in many aspects, it is necessary to be good at obtaining data, analyzing data and using data. Football managers at all levels should also strengthen their study, understand big data, make good use of big data, enhance their ability to use data to promote training and management, improve the efficiency of talent training, and reduce the blindness and deviation of football market operation.

　　Although the concept of big data has been put forward for nearly 10 years, it is still a new thing to become a new stage of information development. China football’s understanding and cognition of this is still in the initial state. It is very gratifying that Shandong Luneng Taishan Club has taken the lead, and it will certainly benefit more than one club. The strategic significance of big data technology is not to master huge data information, but to professionally process these data and realize the "value-added" of data through "processing". It is a means to develop the cause and improve the level. Information system can’t directly improve the level of football in China, but ignoring information or staying in the old view of the role of information can’t meet the new needs of football development.

　　Objective data and scientific analysis are the key functions and values of information systems. On the other hand, if the data is untrue and the analysis is unscientific, then the misleading disaster may be very terrible. Football is originally a highly socialized sport, and big data is the product of the open era. Any idea of being closed and exclusive is incomprehensible to big data. The management information system of Shandong Luneng Taishan Club was established with the cooperation of many domestic and foreign partners.

　　Please cherish this scientific and technological progress and major breakthrough. Football in China has caught up with the new era. In the face of this new topic in the field of football, even if it is slightly behind, it is much smaller than the gap in football competition, and the confidence in catching up with and surpassing the advanced level in the world should be much greater.

CBA News： Basketball Association made a big joke! Expose qi zhou’s offer! Fan Ziming asked not to leave the team.

Fan Ziming’s response attracted the attention and support of the fans. Fan Ziming said that he has regarded Shougang as his second home and has a very harmonious relationship with his teammates. He hopes to stay in Shougang and continue to play for the team. Fan Ziming’s basketball talent can’t be ignored. His height is 2.11 meters, which gives him a certain advantage in the field. However, in recent years, Fan Ziming’s state is not satisfactory, mainly due to injuries, which has led to his state has been declining.

Just as Fan Ziming had doubts about his future, he learned that he was involved in the qi zhou transaction as a bargaining chip. Fan Ziming understands that as a professional basketball player, he has to accept the arrangement and scheduling of the team, but he still wants to stay in Shougang. After all, this team has become his second home.

Fan Ziming’s gratitude and attachment is not limited to the team, but also to the management and teammates of Shougang. He gets along very well with his teammates, helping each other and cooperating flexibly under the basket. They spent a lot of hard training and twists and turns together, and thus established a deep friendship. However, Fan Ziming’s dream came to a turning point, and he was told that he would move to Xinjiang. This is undoubtedly a huge blow to Fan Ziming, who doesn’t want to leave Shougang, let alone be moved to a new environment.

Fortunately, however, the transaction between Shougang and Xinjiang reached a deadlock, and Shougang decided to take the initiative to withdraw. This means that Fan Ziming’s dream has come true. He will stay in Shougang and continue to play for the team. Fan Ziming’s response did not leave the team, which not only showed his loyalty to Shougang, but also showed his desire for survival and his vision for basketball. Fan Ziming hopes to continue to play in Shougang, strive to restore his state and contribute to the team.

A regulation in chinese basketball association recently caused controversy. In the finals of the national U17 women’s basketball competition, a team 30 points ahead of its opponent can only win the runner-up, which makes chinese basketball association’s policy a laughing stock of national basketball. According to the regulations of the Basketball Association, the final result of the game not only considers the competition results, but also includes the physical test results and skill results. Only when all three results are ahead can the team become the final champion. The intention of the Basketball Association is to pay attention to the development of players in many aspects, but if the competition results cannot be used as the standard of champions, the competition will become meaningless. The core of competitive sports lies in the fairness and fairness of competition results. This practice of the Basketball Association deviated from the original intention of competitive sports and caused dissatisfaction among fans and the media.

This provision is not only contrary to common sense, but also has some practical problems. First of all, physical test scores and skill scores can be cultivated and improved, and competition scores are the results that truly reflect the strength of the team. If the results of the game lose the meaning of champion, the efforts and struggles of the players in the game will become worthless. At the same time, this regulation also brings great pressure to referees, because they should not only consider the results of the competition, but also examine the other two results. In addition, the recent transactions about qi zhou have also attracted attention. Qi zhou put forward three additional conditions to Shougang, which caused the transaction to be aborted. First of all, qi zhou hopes Shougang can pay him an annual salary of 25 million, however, this far exceeds the salary cap limit of 6 million stipulated by the Basketball Association. Secondly, he hopes to solve his hukou problem in Beijing, which is relatively easy for Shougang. Finally, he asked for a house in Beijing.

Although Shougang has the ability to meet qi zhou’s requirements, it violates relevant regulations and has a negative impact on the team. The basketball association has set up the salary cap in order to maintain the fairness of the league and avoid the team’s excessive dependence on individual players. The request for housing in Beijing is unfair to other players. Therefore, considering comprehensively, Shougang decided to withdraw from this transaction.

As a popular sport, basketball is often full of various dynamics and changes, which has aroused public concern and heated discussion again and again. Recently, the news of Fan Ziming’s request not to leave the team, the controversy caused by the regulations of the Basketball Association and the latest development of qi zhou trading have become hot topics, attracting many people’s attention. The news that Fan Ziming requested not to leave the team caused widespread concern. As a promising young basketball player, Fan Ziming has been deeply expected by the fans. And his sudden request not to leave the team has aroused many people’s doubts and discussions. Fan Ziming’s action is praised as the embodiment of true love for the team and loyalty, and some people think it is an alternative expression. In any case, the news that Fan Ziming asked not to leave the team will undoubtedly bring more topics and wonderful performances to the basketball world.

The controversy caused by the regulations of the Basketball Association has also become the focus of attention. The rules of the basketball association are to maintain the fairness and order of the basketball game, but sometimes it will cause some controversy. Recently, due to the release of a series of basketball association regulations, it has aroused fierce controversy among fans and the media. Some people think that these regulations limit the performance space of players and damage the appreciation of the game; Some people think that these regulations can better regulate and manage basketball events. The controversy over the regulations of the Basketball Association not only reflects the dynamics and changes in the basketball world, but also is a positive exploration and attempt.

The latest development of qi zhou trading has also attracted wide attention. As an important figure in China’s basketball field, qi zhou’s trade has been attracting much attention. Recently, the news that qi zhou is about to be traded has triggered a heated discussion among fans. This news not only reflects the strategic adjustment and evolution of the team, but also shows the concern and competition of the basketball community for excellent players. The latest development of qi zhou’s trading will become a stirring force for the future development of basketball, and I believe his performance will continue to attract many people’s attention.

To sum up, the news of Fan Ziming’s request not to leave the team, the controversy caused by the regulations of the Basketball Association and the latest development of the qi zhou trade all show the dynamics and changes in the basketball world. These events have aroused widespread concern and heated discussion, and also brought more topics and wonderful performances for the future development of basketball. Basketball is always full of infinite possibilities and variables, so we have reason to expect more news and stories to be displayed in the future development.

2-3！ Cao Meng continued to compete for the championship, and Zhang Linyan was fascinated： one-stop internal cutting+world wave, making 19 goals in the first season

On May 21st, Beijing time, the first leg of the semi-final of the Swiss Women’s Super Playoff started, and Zhang Linyan, a talented woman studying abroad in China, broke out again. With the help of God, this campaign was directly cut in one stop, and she scored a key goal for the Cao Meng women’s football team. However, the Cao Meng women’s football team lost 2-3 to Zurich women’s football team, and it was at a disadvantage to compete for the championship. She needed to win in the second round to have a chance to enter the final.

Cao Meng women’s football team won four consecutive victories before the current round of competition, which strongly impacted the championship trophy, while Zhang Linyan took out the state of winning the championship and losing the hand. She made achievements in four consecutive games, scored three goals and one assist, scored two through-train goals, won the best goal award in a single round and made a wonderful assist. However, the Zurich women’s football team also has an excellent state, and it is also a favorite for the championship, entering the semi-finals with seven consecutive victories.

In this match, the competition between Cao Meng women’s football team and Zurich women’s football team was fierce, and the game was in a stalemate. Zurich women’s football team is slightly superior to Cao Meng women’s football team in both offensive and defensive ends. In the first 68 minutes, Zurich women’s football team leads 2-1; In the 68th minute of the game, Zhang Linyan, who started the game, once again showed her super personal ability. She got a straight ball from her teammates on the right side of the frontcourt, cut the ball directly to get rid of many defenders, and finally shot the world wave with her left foot directly from the arc top of the restricted area, and the ball hung directly in the corner of the top left corner of the goal. Cao Meng women’s football team lost 2-2 Zurich women’s football team, but at the last moment Cao Meng women’s football team lost another goal, and Cao Meng women’s football team finally ended the game 2-3.

The first leg of another semi-final game has also ended. Selvelt defeated St Gallen’s women’s football team 2-1 away and remained unbeaten in the season. This game is 19 wins, 2 draws and 0 losses, which is the biggest favorite to win the championship. Cao Meng women’s football team has 14 wins, 2 draws and 5 losses this season, while Zurich women’s football team has 17 wins, 2 draws and 2 losses. As can be seen from the total score, the stability of Cao Meng women’s football team is not as good as that of Servit and Zurich, so it is difficult to be optimistic about the championship. However, they have Zhang Linyan, the winner of the Swiss women’s super season Golden Globe Award, which greatly enhances their confidence in the championship, and they have the opportunity to complete the counterattack with the star effect in the second round.

Although 22-year-old Zhang Linyan studied abroad in European football for the first time, she made 19 goals in the first season of studying abroad, and her offensive ability was fully recognized. After the regular season, she won the Swiss Women’s Super Official Player of the Season Award, which is a new history for China women’s football players studying abroad. At the same time, she also won the Best 11 Player Award. With such high-light performance, Zhang Linyan needs a championship trophy to end the season. All the last five games have made achievements, and all of them have shown the performance of top stars, which is enough to prove her desire for the championship. There is reason to believe that Zhang Linyan will continue to make achievements in the second round of the semi-final to help the team reverse the promotion.

It is understood that Zhang Linyan’s promotion after studying abroad is very obvious. Her confrontational ability, game rhythm and ball handling ability are all better than in the past, especially her breakthrough ability, which has fulfilled the talent of talented players. Recently, she has made achievements in three consecutive games (including two goalkeepers). According to this growth rate, Zhang Linyan may go further in the new season and challenge the five major leagues.

The reason of C Ronaldo’s bleak evening scene： mistaking the platform for ability

C Ronaldo has gone far away to the desert, so that the hot sunshine in the desert can cure the injury and pain of the defeated plum ball king!

At the age of c, he has gone to the desert, and his competitive career has been finalized.

Although there is a lot of wealth, it seems to be happy! But its heart is painful!

As we all know, Ronaldo is aloof and arrogant, and I am the only one!

I take the super plum ball king as my responsibility all my life, and pursue honor, glory and data all my life.

C Ronaldo has been a technical career for more than ten years, and his money has been free and his wealth has been satisfactory; It cares more about face, scenery and honor.

During C Ronaldo’s career, during his years in Real Madrid, he won four Golden Globes and four Champions League games, which strengthened his confidence and courage, boasted himself the first, second and third place in the world, was extremely inflated and self-mad.

C Ronaldo’s greatest misfortune is to regard the platform as an ability! It is the real Madrid platform and personal efforts that have made its real Madrid years dazzling!

C Ronaldo left Real Madrid, moved to Juventus and Manchester United, accomplished nothing, and never won the Golden Globe Award, Sir, or the Champions League again! 16 lang in the Champions League every year! Its juventus years are incomplete!

C Ronaldo’s national team was ruined, and fans said that it was lying in the European Cup. Although it was exaggerated, it was not groundless!

C Ronaldo’s World Cup achievement is hands-free, which is a stain on his life! Causing 10 zeros in the World Cup to be bleak. Single-core team leader has the best score in the top 16.

After the dark years after Real Madrid, nothing was achieved after the World Cup.

C Luo Fang understands that it is the Real Madrid platform and Lafayette that have made its brilliant Real Madrid era. I mistook the Real Madrid platform for my ability, woke up like a dream, and wanted to return to Real Madrid and relive the beauty. But the vicissitudes of life, powerless, was rejected by Real Madrid! I have to go to Saudi Arabia to waste the rest of my life!

Life is like this, when you miss the opportunity, it may be a lifetime of regret and regret!

What does offside mean in football match？ Will your own team be offside in the half court？

Offside is a professional term in football match, which first appeared in the Rules of Football Match promulgated in 1874. It is defined as: when the ball is passed in front of the attack direction, when the football kicks out, if the teammate of the defensive half is closer to the goal than the penultimate defender of the other side, and wants to use this position to interfere with the game or gain benefits, the player will be sentenced to offside.

There are many technical terms in football matches, such as penalty kick, corner kick, sideline kick, offside, etc. Among them, offside is often heard by many people, but its basic meaning is still ambiguous, and sometimes it is impossible to make an accurate judgment under special circumstances. Let’s explain it in detail below.

When we watch a football match, we often see a sideline referee raise a flag just after a player scores the ball into the opponent’s goal. The player who scored the goal has to shake his head helplessly and throw himself back into the attack. Naturally, the goal just scored will not count. Why? Because he was offside, he was offside at the moment when his teammates passed the ball to him.

Which position on the court is offside? In fact, there is no specific position, depending on the position of the players. First of all, offside can only happen in the opponent’s half court. At the moment when our own players pass the ball, we should observe the positions of all the players. When the player who is ready to catch the ball is at the forefront of all the players (excluding the goalkeeper of the opponent), he is offside. This position is not the position of his feet, but the position of his body, and his shoulders and head are leading.

In the past, offside was judged by the sideline referee with the naked eye, which naturally could not be absolutely accurate. But now, with the introduction of high-tech VAR technology, many offsides between millimeters can’t escape from the "eyes". However, although VAR makes the game fairer, it also reduces the excitement of the game to a certain extent and makes many beautiful goals invalid.

There are some special situations about offside on the court. For example, although the attacking player who receives the ball is ahead of all the defensive players (except the goalkeeper), he is still in his own half, so he is not offside at this time.

If a player on the attacking side is offside at the moment when the player passes the ball, but he doesn’t catch the ball or participate in the next attack, then he is not offside.

The last situation: although a player on the attacking side is in an offside position, he just runs with him, participates in the stall, and creates shooting opportunities for his own players, but he never touches the ball from beginning to end. Is he offside? Real fans, please tell me in the comments section.
