Pa-Hng has long been recognized as divergent. Benedict (1986) argued that one of its dialects constituted a separate branch of the Miao–Yao family. Ratliff (2010) found it to be the most divergent Hmongic (Miao) language that she analyzed. This Bahengic branch also includes Younuo (Yuno) and Wunai (Hm Nai).
Pa-Hng speakers are called by the following names (Mao & Li 1997).
- pa˧˩ŋ̥ŋ˧˥ (巴哼)
- m̥m˧˥nai˧ (唔奈)
- Red Yao (红瑶)
- Flowery Yao (花瑶)
- Eight Surname Yao (八姓瑶)
In Liping County, Guizhou, the Dong people call the Pa-Hng ka˧˩jiu˧ (嘎优), while the Miao people call them ta˥tia˦˨ju˧ (大达优). In Tongdao County, Hunan, the Pa-Hng (xeŋ˧) are also known as the Seven Surname Yao 七姓瑶, since they have the seven surnames of Shen 沈, Lan 兰, Dai 戴, Deng 邓, Ding 丁, Pu 蒲, and Feng 奉.
In China, Pa-Hng speakers are classified as Yao, even though their language is Hmongic rather than Mienic.
Mao & Li (1997) splits Pa-Hng into the following subdivisions, and most closely related to Hm Nai:
- Pa-Hng proper (巴哼 pa˧˩ŋ̥ŋ˧˥)
- Hm Nai (唔奈 m̥m˧˥nai˧)
Vocabulary word lists for these three Pa-Hng varieties can be found in Mao & Li (1997). An additional dialect is found in Vietnam.
- Northern Pa-Hng: Gundong 滚董, Liping County 黎平, Guizhou
- Southern Pa-Hng: Wenjie 文界, Sanjiang County 三江, Guangxi
- Hm Nai: Huxingshan 虎形山, Longhui County 隆回, Hunan
The Na-e dialect (also known by the Vietnamese rendition of Pa-Hng, Pà Then [Pateng]), is a geographic outlier. Paul Benedict (1986) argued that it is not actually Pa-Hng, or even Hmongic, but a separate branch of the Miao–Yao language family. However, Strecker (1987) responded that it does appear to be a Pa-Hng dialect, though it has some peculiarities, and that Pa-Hng as a whole is divergent.
Jerold A. Edmondson has reported Pa-Hng dialects in Bac Quang District and Hong Quang Village of Chiem Hoa District in northern Vietnam, and found that they were most closely related to the Pa-Hng dialect spoken in Gaoji Township 高基, Sanjiang County, Guangxi.
Pa-Hng speakers are distributed in the following counties in China. Most of the counties have 1,000 - 6,000 Pa-Hng speakers (Mao & Li 1997).

Pa-Hng is also spoken in small pockets of northern Vietnam. In Vietnam, the Pa-Hng are an officially recognized ethnic group numbering around a few thousand people, where they are called Pà Thẻn. Na-e as reported by Bonifacy (1905) is also found in northern Vietnam.
- Tân Trịnh, Quảng Bình District, Hà Giang Province, Vietnam (Niederer 2004)
- Bắc Quang District, Hà Giang Province, Vietnam
- Minh Thương Village, Tân Lập Township
- Tân Thịnh Township
- Hồng Quang Village, Chiêm Hoá District, Tuyên Quang Province (62 km northwest of Chiêm Hoá City), where the speakers are known as Mèo Hoa (Flowery Miao)
According to Vu (2013:12-15), the ancestors of the Pà Thẻn had first migrated from Guangxi to Hải Ninh (now Quảng Ninh Province), and then from Hải Ninh to the Thái Nguyên area. The Pà Thẻn then split off to settle in three main areas.
- Linh Phú (Chiêm Hóa District, Tuyên Quang) and Trung Sơn (Yên Sơn District, Tuyên Quang)
- Lăng Can (Na Hang District, Tuyên Quang), Hồng Quang (Chiêm Hóa District, Tuyên Quang), and Hữu Sản (Bắc Quang District, Hà Giang)
- From Xuân Minh (Quang Bình District, Hà Giang), the Pà Thẻn migrated to the communes of Yên Bình, Yên Thành, Tân Trịnh, Tân Nam (all in Quang Bình District, Hà Giang) and Tân Lập (Bắc Quang District, Hà Giang).
