The Changqi Cup is a Go tournament held by the Zhongguo Qiyuan dedicated to Ing Chang-ki.
Starting in 2008, the tournament began in May and ended in October.
Players compete in a preliminary tournament to qualify.
After the preliminaries, 30 players compete in a single elimination tournament, with the previous year's finalists being directly seeded to the second round.
The Changqi Cup is one of the few professional tournaments to use Ing rules.
