Xie Xuan
Xie Xuan (謝玄) (343–388), courtesy name Youdu (幼度), formally Duke Xianwu of Kangle (康樂獻武公), was a Jin Dynasty (265-420) general who is best known for repelling the Former Qin army at the Battle of Fei River, preventing the Former Qin emperor Fu Jiān from destroying Jin and uniting China.
Early career
Xie Xuan's father Xie Yi (謝奕) was an older brother of the Jin prime minister Xie An. Xie Xuan's sister Xie Daoyun (謝道韞) was known for her literary talent and quick wit. Early in his career, both Xie Xuan and his uncle Xie An served on staff of the paramount general Huan Wen. Huan Wen greatly prized Xie Xuan's ability, and once commented, with regard to him and his colleague Wang Xun (王珣), both of whom served as his secretaries:
After Huan Wen's death in 373, Xie Xuan initially served on the staff of Huan Wen's brother Huan Huo (桓豁). In 377, when the imperial government was looking for a general capable of defending the northeastern border (modern Jiangsu) against Former Qin, Xie An, against the usual custom of not recommending one's own clan members, recommended him. The official Chi Chao (郗超), who ordinarily feuded with Xie An on nearly all matters, immediately remarked, "Xie An, in his good judgment, made an uncommonly good move against public sentiment, and Xie Xuan would surely not fail his expectations." Chi made these remarks based on the time when he also served on Huan Wen's staff and saw Xie Xuan's abilities.
