Wūsā

Wusa was a Yi highland polity around present-day Weining and Hezhang, west of the Wumeng mountains. The Yuan organized it as Wusa Route under the Wusa-Wumeng pacification command.

In 1381 the Ming made Yi chieftain Shibu native prefect of Wusa, establishing a military guard there in 1382. The An clan held the hereditary office until An Chongsheng joined An Kun's revolt against the Qing in 1664. The Qing defeated the rising in 1665 and replaced Wusa with Weining Department under Guizhou in 1666.
