The Tianyuan (Chinese: 天元; Pinyin: Tiān Yuán) is the name of a Go competition in China organized by the Chinese Weiqi Association. The word tiānyuán literally means the center or origin of heaven, and is the center point on a Go board. The Tianyuan is equivalent to the Nihon Ki-in's Tengen and the Hanguk Kiwon's Chunwon.
The Tianyuan competition is sponsored by the Zhongguo Qiyuan, New People's Evening News, and New People's Weiqi Monthly Magazine. It consists of a preliminary tournament in which 32 players compete against one another to determine the challenger to the previous year's winner. The preliminary is a single-elimination format, and the title match is decided in a best-of-three. The winner's purse is ¥250,000 ($39,026) and ¥100,000 ($15,611) for the runner-up, as of 2018.
