Classified as Han nationality. It differs greatly from both Southwestern Mandarin (Xinan Guanhua) [cmn] and Xiang Chinese (Hunanese) [hsn], but is relatively uniform within itself. Neighboring Han Chinese, Miao, and Tujia people do not understand it. Some view it as a special variety of Chinese, others as a minority language, perhaps related to Miao.
Officially classified within the Han nationality.
