Yúnnán

Yunnan County lies east of Dali on an old road through the highlands. Its name is far older than the province that later bore it: a county was established here under the Han, with its seat at what became Yunnan Post Station. The post continued to serve travelers under the Yuan, Ming and Qing. In the early Ming, the county seat was moved to the vicinity of the Erhai Guard's walled garrison, while the old post remained on the road.
