Divided into four groups, group A has four teams, group B has five teams, group C has five teams, and group D has four teams. The top two teams qualify and then cross out. Among them, the first place in group A is second to group C, the second place in group A is second to group C, and the first place in group B is second to group D. The second pair in group B is the first in group D, and the winner enters the top four and the loser is eliminated. Then the four winners draw lots to decide the semi-final opponents. The winner enters the third place in the championship, and the loser can tie for the third place or play the play-offs for the third and fourth places.
But I don't know what game this is. Badminton and table tennis can be tied, football and basketball can compete for the third place, and the game can decide the outcome.
