Where is Yuexi Prefecture in Yunnan Province in the 55th year of Qing Qianlong?

There is no place name "Yuexi House" in history, but there is a homophonic "Yuexi Hall", which belongs to the neighboring Ningyuan House in Sichuan, that is, Yuexi County today.

At that time, the government administered Yunnan:

Yunnan, Wuding, Dali, Heqing, Lijiang, Yongbei, Yongchang, Shunning, Chuxiong, Yao 'an, Jingdong, Hua Meng, Pu 'er, Qujing, Zhaotong, Chengjiang, Guangnan, Dongchuan, Hua Kai, Lin 'an, Yuanjiang and Zhenyuan in Guangxi.
