In the first edition, 20 players participated in the final knock-out tournament (the preliminaries were ten robin rounds).
From the second edition on, the knockout section became very large, incorporating in that second edition what seems to have been 61 players.
In every version, the format has included some amount of seeding, but the manner of that seeding has varied. In some cases it would be better described as "anti-seeding" or "secondary preliminaries", in which only a minority of players were obliged to play in the first round.
See the Go To Everyone! section for more details.

The 9th (2021) edition is currently in progress. The finalists are the very established (although still young) Wang Yuanjun and prodigial new face Chen Qirui. Each has won one game, meaning that the match will be decided by the next, to be played on November 21. Lai Junfu and Xu Haohong were semifinalists.
