Möng Hkeng

Möng Hkeng was a small Tai Nüa Shan chiefdom in the Yongchang frontier hills of western Yunnan, around present-day Zhenkang on the border facing Burma's Kokang district. Such Chinese Shan chiefdoms gained room to themselves after the Mongols overthrew Dali in 1253, and were later enrolled as tusi, becoming the Yuan Zhenkang military administration and the Ming-Qing Zhenkang native prefecture.
