Měngdǒng

Měngdǒng lies in the mountainous border country of southwestern Yunnan. It is associated with the Mengjiaodong hereditary chieftaincy, whose centre was at Mengdong. The district linked Tai and Wa communities across valleys and uplands.

In 1771 the Gengma chief Han Chaoyuan placed his brother Han Chaojin in authority over Mengjiao and Mengdong. A conflict over Gengma in 1784 led to Qing intervention: Han Enqing was killed, another chief appointed, and the Mengjiaodong jurisdiction placed under Zhenbian.
