Zhèng'ān
Zhèng'ān stands in the mountains of northern Guizhou, in a region long governed by hereditary native chiefs. Under the Ming, the Zhēnzhōu chiefship was subordinate to the rulers of Bōzhōu. After the defeat of Bōzhōu in 1600, the chief Zhèng Kuí submitted to the Ming and was retained as a native deputy in the new Zhēn'ān Zhou. The seat of the new administration moved several times. It was first established at Yùshuǐyuán, moved to Wúliǎnbà in 1620, and then to the foot of Gǔfèng Mountain in 1662. In 1724 the Qing renamed the jurisdiction Zhèng'ān to avoid the personal name of the Yongzheng Emperor; four years later it passed with Zūnyì Prefecture from Sichuan to Guizhou.
