Four teams in each group will play home and away double round robin matches, and the ranking method will be determined in the AFC Champions Group Match:
(1) Each team wins a game with 3 points, draws a game 1 point, and loses a game with 0 points;
(2) The team with more points ranks first;
(3) If two or more teams score equally, arrange them in the following order:
Team A with equal points will be ranked first if there are more points in the competition between them.
Teams with equal B scores have more goal difference, ranking first;
C, the team with equal points scored more goals in the opponent's game, ranking first;
D, the team with equal points has more goal difference in all competitions in this group, ranking first;
Teams with equal E scores scored more goals in all competitions in this group, ranking first;
F if the two teams meet in the last game, kick the penalty to win;
G red and yellow cards ranked first;
H draw lots to decide the ranking.
