Biography

Yujiulü Doulun's reign Yujiulü Nagai and his nephew Khagan Yujiulü Doulun fought against Gaoche ruler Afuzhiluo (阿伏至羅) and his cousin Qiongqi (穷奇). In 487 Afuzhiluo, Qiongqi and their clans of over 100,000 yurts escaped from the pursuing armies Doulun and Nagai. While Doulun had limited success, Nagai won all his battles against the Gaoche.

He directly drove Woye Town (now northeast of Urad Front Banner, Inner Mongolia), Huaiyu Town (now southwest of Guyang County, Inner Mongolia) and went to Dai Commandery and Heng Commandery, however he was eventually stopped by Wei general Yuan Huai (源怀).

He died in 506 and was succeeded by Yujiulü Futu.
