Qiang people
Many of the Xianbei tribes migrated south and settled on the borders of the Wei-Jin dynasties. In 258 Tuoba Liwei's people settled in Yanmen Commandery. The Yuwen tribe settled between the Luan River and Liucheng. The Murong and Duan tribes became vassals of the Sima clan. An offshoot of the Murong tribe moved west into northern Qinghai and mixed with the native Qiang people, becoming Tuyuhun.
