Làngqú

Langqu lies in the mountains north of Beisheng, between the upland districts of Yongning and the valleys farther south. The Yuan established Langqu Prefecture in 1279, replacing an earlier local district known as Luogong. It remained a hereditary native prefecture under the Ming. In the Qing period the A family held authority here alongside other hereditary chiefs of the Yongbei district, whose territories spread across the mountains and valleys of northwestern Yunnan.
