The four varieties of Pingtang were listed as unclassified branches of Chuanqiandian Miao (Western Hmongic) in Wang (1983). Li (2000) classified them together as one of eight branches of Western Hmongic, a position maintained in Wu and Yang (2010).
There are four varieties of Pingtang according to Li (2000):
- North (Strecker's Pingtang Miao), 11,000 speakers
- East (Strecker's Dushan Miao), 4,000
- South (Strecker's Luodian–Pingyan Miao), 6,000
- West (Strecker's Wangmo–Luodian Miao AKA Mhang), 3,000
These are at approximately the distance of the varieties of the other branches of West Hmongic, which Ethnologue assigned separate ISO codes.
