Nán'ān
Nan'an lies south of Weichu in the mountains of central Yunnan. The settlement was once known as Mochu, a name associated with the people who lived there before the Yuan conquest. The Yuan first established a military office at Mochu and in 1275 replaced it with Nan'an Prefecture, subordinate to Weichu. The name meant the southern part of the Weichu country. Under both the Ming and Qing, Nan'an remained a prefecture within Chuxiong, preserving its place as a local centre in the uplands.
