Peiping in the 1920s. In a warlord birthday banquet chess meeting, Japanese go master Songbo (Mikuni Rentaro) and Jiangnan chess king Kuang Yishan (Sun Daolin) met. Unwittingly Songbo found Kuang Zi Aming (Shen Guanchu) talented and intelligent and intended to accept him as an apprentice. Songbo had just placed a son in the "Tianyuan" position, unexpectedly, Kuang Yishan was suddenly arrested by the police. After Song Bo rescued Kuang Yishan, the time for his return has come, leaving the unfinished game of residual chess. A few years later, Kuang Yishan sold his family business and sent his son to Japan. Before leaving, he handed over the folding fan with the word "Fengfei" to his son and told him to learn chess well and revitalize the chess scene of the motherland in the future. In 1937, the Japanese aggressors launched a full-scale war of aggression against China, and Amin, who had obtained the "heavenly throne," refused the Japanese authorities' request for him to become a Japanese citizen, and was killed by the Japanese army when he decided to flee to China. Kuang Yishan in Wuxi also suffered great misfortune and humiliation because he refused to play against the Japanese army.
