Like the current tournaments, most of the series are played in groups first. You 65,438+07 people can be divided into four groups (draw lots to group A, group B, group C and group D). Four people in each group will play round robin, take the top two in the group, and then play the second stage of the competition: A1C2B1C2C1B2 (8 into 4).
If you don't understand, you can ask.
