Murong Huang
Yuwen were descendants of the nomadic Xiongnu who became assimilated with the Xianbei after 89 CE and ruled the Kumo Xi and Khitan (both Mongolic peoples) before being defeated by Murong Huang in 344 CE, upon which Yuwen separated from the Kumo Xi and Khitan. The language of the Yuwen is thought to be Turkic or a very distant branch of Mongolic.
