費禕
Fei Yi (died 16 February 253), courtesy name Wenwei, was a regent and military general of the state of Shu during the Three Kingdoms period of China. Born in the late Eastern Han dynasty, Fei Yi started his career as an attendant to Liu Shan, the eldest son and heir apparent of Liu Bei, a warlord who became the founding emperor of Shu. After Liu Shan became emperor in 223, Fei Yi gradually rose to prominence under the regency of Zhuge Liang, the Imperial Chancellor of Shu. During this time, he concurrently served as a military adviser under Zhuge Liang and as Shu's ambassador to its ally state Wu. He also played a significant role in the conflict between the Shu general Wei Yan and Zhuge Liang's chief clerk Yang Yi. After Zhuge Liang's death in 234, Fei Yi served as a deputy to the new regent Jiang Wan and progressively assumed greater responsibilities as Jiang Wan gradually relinquished his powers due to poor health. In 244, Fei Yi led Shu forces to victory at the Battle of Xingshi against their rival state Wei and succeeded Jiang Wan as regent of Shu two years later following the latter's death. On the first day of the Chinese New Year in 253, Fei Yi was assassinated by a Wei defector, Guo Xiu.
