Good stuff, TiP blowing themselves up just when it looked like they were ready to mount a huge challenge in playoffs, and even secure a bye.
Check out China's new playoff format, complicated even by the intricate standards of Chinese MOBA tournaments:

So 7th seeds plays the 8th seed, winner plays the 6th. Both matches are Bo5, both losers are out, leaving 5 teams standing.
The team that made it through the preliminary bracket plays a Bo5 against the 5th seed, which serves to determine who their next opponent will be - the winner plays the 4th seed, the loser the 3rd seed. Those two matches are also Bo5s and the losers are knocked out.
Then, the two surviving teams play the 1st and 2nd seeds in Bo5s in the playoff Semi-Finals, with the winners contesting the final.
And after all that, I'm sure there will be another tournament held soon after to determine Worlds qualification (excluding the Summer Split winners, who will already be qualified I think).
