According to Li (2006:340), there are fewer than 1,000 speakers living on the slopes of the "Kongge" Mountain ("控格山") in Na Huipa village 纳回帕村, Mengyang township 勐养镇, Jinghong 景洪市 (a county-level city).
Hu speakers call themselves the xuʔ˥, and the local Dai peoples call them the "black people" (黑人). They are also known locally as the Kunge people 昆格人 or Kongge people 控格人 (Li 2006).
