Other introductions of the knockout stage:

In the single elimination system, the organizing Committee will arrange all the players in advance according to the preliminary ranking or seed order, and also support some seed players to participate directly in the middle round (that is, bye-bye). The purpose of doing this is to avoid the premature meeting of the strong players, which will lead to the disparity in strength between the two sides in the following games and affect the suspense and excitement of the game.

After the round-table meeting is arranged, each team draws lots, fills in the round-table meeting according to the number drawn by each team (or determines the number according to the ranking order of the last game), and then prepares the competition schedule.

When compiling the competition schedule, we should first implement the principle of equal opportunity and fair competition, and of course, we should also take care of the needs of the competition (audience) appropriately. We can adjust the time (morning, afternoon, evening), venue (large or small pavilion), region (local or foreign) and other aspects to achieve a general balance between teams.
