Mi Fang
Mi Fang ( 190s–223), courtesy name Zifang, was a Chinese military general and politician serving under the warlord Liu Bei in the late Eastern Han dynasty. He was also the younger brother of Mi Zhu, who also served Liu Bei. In 219, Mi Fang surrendered to Liu Bei's ally-turned rival Sun Quan, directly resulting in the loss of Jing Province (covering present-day Hubei and Hunan) and the death of Guan Yu. The Australian sinologist Rafe de Crespigny notes that Mi Fang had the remarkable record of serving each of the leaders of the Three Kingdoms during his lifetime.
