Duan Wuwuchen
Duan Wuwuchen (段務勿塵) (died December 310 or 311), also known as Duan Wumuchen (段務目塵), was a chieftain of the Duan-Xianbei during the Jin dynasty (266–420) and Sixteen Kingdoms period. A vassal of the Western Jin, his leadership saw the Duan begin actively providing military assistance to the Jin through his alliance with the Inspector of You Province, Wang Jun. For his merits, he was named the Duke of Liaoxi, a title that was passed down to his successors.
