Ānnán

Ānnán was a native chieftaincy around Laozhai in south-eastern Yunnan, on the road toward Đại Việt. Under the Yuan its predecessor was an escort-army thousand-household post guarding the frontier.

When Ming forces reached Lin'an in 1382, the officer Na You surrendered and became deputy chief of the new Ānnán office. In nearby Mengzi the hereditary Lu magistrates died out in 1523, and circulating officials took over. In 1645 Sha Dingzhou, chieftain of nearby Ami, rose in revolt; Daxi forces under Li Dingguo and Liu Wenxiu defeated him, and he was executed in 1648.
