The team that has accrued the most championship points over the 2021 Season (and wasn't automatically qualified) also qualifies for the Main Event as China's second seed.
China's third and fourth seeds (if there is) for Worlds are determined at the Regional Finals.
The top 4 (3 if only 3 seeds) teams in championship points (that are not already qualified for Worlds) play in the Regional Finals.
In the event that multiple teams are tied in the standings at the conclusion of the Summer Split, then the team that gained the most points in the Summer Split will be considered the holder of the tiebreaker.
