The competition form of Asian Football Association Cup

The competition form of AFC Cup is similar to AFC Champions Cup. Each country or place sends two teams (usually league champions and cup champions), which are divided into seven groups. Four teams in each group will play a double round robin tournament with the host-guest system, and the champion of the group and the champion of Wei Huang will draw lots for the elimination of the quarterfinals with the host-guest system to decide the champion team.
