In order for the national football team to have a good result in the World Preliminary Round, the Chinese Football Association sacrificed the Chinese Super League. Today, the national football team has broken in the World Preliminary Round, and the fiasco has fallen to the bottom of vietnam. Seeing that the Chinese Super League is also half dead, and the fans who pay attention to it are getting less and less, the Football Association is a bit anxious. According to the Beiqing Daily, the Chinese Football Association wants to restore the home-and-away system in the 2022 season and hopes to bring the Chinese Super League back on track. However, one thing is difficult to understand and has to be calculated with a "complex" mathematical problem.

According to the Beiqing Daily, the new season of the Chinese Super League will not start until April 23 at the earliest. Moreover, it also wants to close a week before the start of the World Cup in Qatar, that is, around November 13. Looking back at the normal season of the Chinese Super League, it usually starts around March 1-3 and then closes around November 1-3, and the whole season lasts for 8 months. Why does it take so long?
Each round of home-and-away play will have 1/1/2 teams flying away from home. When you come and go, you need to delay for 2 days on the road. If you want players to regain their fitness, the interval between rounds of matches can generally not be less than 4 days. In addition, it takes at least 2-3 days for each round to complete. Coupled with the national team match days, it takes almost 8 months for the Chinese Super League to come down the whole season. And that's when there are only 16 teams. In the new season, the Chinese Super League expanded to 18 teams, which means that there will be 4 more rounds of matches in the whole season.
The four rounds of competition require 8 days per round of 2 days, plus the 12-day interval, and the new season has 20 more days than before. According to the normal schedule, the opening of March 1 will also be mentioned at the end of November. However, according to the Beiqing Daily, the new season will start as soon as April 23, which is nearly two months later than the normal league. However, it will close on November 13. In other words, the FA has only 6 and a half months left for the new season.
18 teams, 34 rounds. Even if you play in 2 days, it will take 68 days for 34 rounds. There are 33 interval rounds in the 34 rounds, 4 days is 132 days, 68 + 132 = 200 days, which is equivalent to 7 months. Moreover, the time of the national team matchday has not been thrown away in the middle, and it has exceeded 6 and a half months. So if the FA really wants to resume home and away, is 6 and a half months enough?
In other words, the tournament system can also compress the schedule. The resumption of home and away games will certainly not compress the schedule, otherwise there would be no fairness. At present, I want to play 34 rounds in such a short period of time. Only the rest time between rounds is compressed, and the 4 days are compressed into 3 or even 2 days. In this way, the Chinese Super League is likely to play all 34 rounds of matches in 6 and a half months. However, shortening the rest time of players cannot guarantee the physical fitness and quality of training of players, and even lead to large-scale injuries to players.
So, it started on April 23 and closed on November 13, not the FA and we made a joke. It is the Football Association that has given itself a problem, a mathematical problem that cannot follow the laws of football. According to my personal opinion, it is only February, and the FA should not seize the time to prepare for the start of the competition in early March.
