Tiānquán

Tianquan was a Gyalrong tusi chiefdom west of Yazhou. Under the Yuan, the Gao and Yang families held investitures, governing from Shiyang and Diaomen respectively.

They submitted to the Ming in 1371, and in 1373 their offices were merged, with the Gao as principal and Yang as vice chief. A Gao revolt was crushed in 1521. The families submitted to the Qing in 1652; the chiefdom was abolished in 1729 and replaced by Tianquan Department.
