What is "huchuquan"

Huchuquan was the elected Chanyu (r. 195-216) of the southern Xiongnu during the late Han Dynasty and Three Kingdoms period of Chinese history. Huchuquan was a younger brother of the puppet Yufuluo (who was in exile). He also was appointed to the Chanyu position by the Han imperial court following the slaying of their father Qiangqui, also a Han appointee from an ineligible succession line.
