The China League One is the top division in Chinese football and has 18 teams competing for promotion to the top tier of Chinese football, the China Super League. The competition is divided into two phases - the regular season and playoffs.
The regular season runs from August to November, with each team playing 22 games against other teams in their league. The top four teams at the end of the regular season qualify for the playoffs, which take place in January and February. In the playoffs, the top two teams play in one match while the bottom two teams play in another match. The winner of this match then plays the runner-up in the final match of the playoffs.
In addition to the playoffs, there is also a promotion/relegation playoff that takes place every year between the top two divisions of Chinese football, the China League One and the China League Two. This playoff matches the top two teams from the China League Two against the bottom two teams from the China League One. The winner of this match then moves up to the China League One while the loser stays in the China League Two.
Overall, the China League One is a highly competitive league with many talented players and passionate fans. It is an important part of the Chinese football landscape and provides opportunities for aspiring professional footballers to showcase their skills on the world stage.
