The Buyang people are an officially unrecognized Kra ethnic group living in Wenshan Prefecture, Yunnan and Napo County, Guangxi in China.
According to the Napo County Gazetteer (那坡县志), this exonym dates back to the Qing Dynasty, when the "Six Yao" lived in the villages of Nianyi 念益, Guolie 果列, Yancun 燕村, Rongtun 荣屯, Gonghe 共和, and Shanhe 善合.
The third brother who migrated to Vietnam could have been the ancestor of the En (Nung Ven) or the Qabiao people.
A Qing-era chronicle had also mentioned a people called the Puyang 普央 living in Guangnan (Li & Luo 2010).
According to Holm (2003:15),[2] the Buyang used to build hanging coffins, including hanging coffins on cliffs above a large bend in the Hongshui River near Banwen village 板文村, Sihe Township 四合乡, Donglan County, Guangxi.
