Fei Wei (?-253 A.D.) was a native of Jiang Xia (West of Lou Shan in Henan), and a general of Shu during the Three Kingdoms. When Zhuge Liang (Zhuge Kong Ming) returned from his expedition to the south, Fei Wei was in the same chariot with him. Everyone was surprised and wanted to know why Fei deserved such honor. Zhuge allowed Fei to travel with him, because he respected Fei'd talent and ability. Before Zhuge died in 233 A.D., he proposed that Fei should replace him as the prime minister. Within two years, Fei indeed became the prime minister of Shu. In 243 A.D., he resigned his position and became a general. Interestingly, what Zhuge liked about Fei, was his ability as a general. In 244 A.D., general Cao Shuang of the Wei kingdom led a hundred thousand army to attack the north-east Shu kingdom from Lejiu. Emperor Liu Chan (son of Liu Bei) heard the news and was dead worried. Fei Wei asked Emperor Liu Chan to relax, because he had a good defensive plan. The next day, Liu Chan sent Lai Ming to learn about his plan. When Fei saw Lai, he said, 'Officer Lai. You come at the right time. Let's play a game of Weiqi.' Lai Ming thought he was kidding, but Fei asked his guard to set up the game for them. When they were playing, messangers came one after another to report on the war. Lai was ready to adjourn the game when Fei said, 'The development of the war is like this game. Shenling, Wuling and Fengshuiling are on the outside of Shaanxi. If we can occupy these three mountains, we can surround our invaders.' When Lai Ming looked at the Weiqi board, he discovered that his black stones have been surrounded by White and realized that Fei Wei was using the Weiqi game to direct his army. After the game, Fei said goodbye to Lai, put on his armor and proceeded to join the attack. Cao Shuang's army was tired due to the long journey and shortage of supply. They were surrounded by the Shu army and were badly defeated.
