Rules of 202 1 Spring Tournament: In the regular season, the home and away match system of Group S (6 players), Group A (6 players) and Group B (4 players+temporary team) is implemented: it is divided into group I single cycle (BO5), group II single cycle (BO5), berth race (BO5) and group III single cycle (BO5). Add the transport party selection system.
Single-cycle S, A and B teams will play one game each. After the second single cycle, the standings S5-A2, S6-A 1, A5-B2, A6-B 1 played against BO5, and the winner entered a higher group. The way of "changing groups" is the same as the card game, so there is no need for competition, so the first single cycle will change the standings.
After the card game, Group B will be eliminated directly, and Group S and Group A will decide the playoff places in the third round.
