West Hmongic languages
The West Hmongic languages, also known as Chuanqiandian Miao () and Western Miao, are a major branch of the Hmongic languages of China and Southeast Asia.

The name Chuanqiandian is used both for West Hmongic as a whole and for one of its branches, the Chuanqiandian cluster.

Names
Autonyms include:

 Hmong  (Bijie and Wenshan Prefecture, Guizhou)
 Huishui Miao  (Huishui County, Qiannan Prefecture, Guizhou)
 Mashan Miao  (Ziyun County, Anshun, Guizhou)
 Luobo River Miao  (Fuquan, Qiannan Prefecture, Guizhou)  
 A-Hmao  (Weining County, Bijie, Guizhou; Zhaotong and Chuxiong Prefecture, Yunnan)

Classification
West Hmongic is the most diverse branch of the Hmong (Miao) language family. There are nine primary branches in Chinese sources, though the unity of these are not accepted in all Western sources.

 Chuanqiandian cluster
 Hmong‡
 Gha-Mu (Small Flowery Miao)
 Xixiu Miao
 Chong'an River Miao
 Gejia
 Dongjia
 Bu–Nao‡
 A-Hmao (Big Flowery Miao, Northeast Yunnan Miao)
 A-Hmyo (Luobohe Miao)
 Guiyang Miao‡
 Huishui Miao‡
 Mashan Miao (Mang, Hmang)‡
 Pingtang Miao‡

Items marked ‡ have been split into individual languages (and not kept together) by either Matisoff or Strecker; all of these are branches of Miao listed with subbranches in Chinese sources. The other three (A-Hmao, A-Hmyo, Gejia) are not so divided in either Chinese or Western sources. The three divisions of the Chuanqiandian cluster are only as divergent as the divisions of the other branches marked ‡, but are listed separately due to the internal complexity of Hmong.

The various varieties of Pingtang, new branches of Guiyang and Mashan, and Matisoff's Raojia and Pa Na are not listed in Ethnologue 16 and have no ISO codes. Matisoff (2006) gives very different names, and it's not clear how these correspond to the branches listed here.

Wang (1983)
Wang Fushi, summarized in English by David Strecker, emphasized the diversity of Western Hmongic. The names below are from Strecker; Wang did not assign names, but identified the districts where the varieties were spoken.

Chuanqiandian (Sichuan–Guizhou–Yunnan)
Chuanqiandian subgroup
Hmong (Chuanqiandian cluster: White Hmong, Green Mong, etc.)

Huishui (Mhong)
Mashan (Mang)
Luobo River (A-Hmyo)
Eastern or Zhong'an River (Mhong, Gedou)
? Pingtang
? Qianxi–Pingba–Qingzhen–Liuzhi (= Li Yunbing's Qianxi)
? Luodian Muyin (Moyin)
? Dushan
? Luodian Pingyan
? Ziyun–Zhenning (= Li Yunbing's Ziyun)
? Wangmo

Pu–Nao (= Bu–Nao)
Pu Nu [Tung Nu] (= Bunu, Dongnu)
Nu Nu
Pu No (= Bunuo)
Nao Klao (= Baonao)
Nu Mhou (= Numao)

These are not all established as unitary branches, however. In a follow-up, Strecker broke up Bu–Nao on the basis of newly accessible data, and noted that several of the languages listed by Wang (marked "?" above) were unclassified due to lack of data and had not been demonstrated to be West Hmongic. The other groups are then listed as unclassified within Hmongic, and not specifically West Hmongic. However, Wang (1994) identified two as varieties of Guiyang. The eight unclassified languages are all spoken in a small area of south-central Guizhou, along with Guiyang, Huishui, Mashan, and Luobo River Miao. These were later addressed by Li Yunbing (2000).

Wang (1985)
Wang Fushi later grouped the Western Miao languages into eight primary divisions. Datapoint locations of representative dialects are from Li Yunbing (2000:237), all of which are located in Guizhou province, China.

Southern (7,000 speakers; representative dialect: Pingyan 平岩乡, Luodian County)
Western (3,500 speakers; representative dialect: Youmai village 油迈村, Youmai township 油迈乡, Wangmo County)

The above classification was later revised by Li Jinping & Li Tianyi (2012:285) to include 7 dialects instead of the 8 given by Wang; Pingtang Miao is excluded.

Li (2000)
Li Yunbing classified those varieties left unclassified by Wang, grouping four of them together as an eighth branch of West Hmongic, Pingtang. He identified Luodian Muyin and Wangmo (using Strecker's names) as varieties of Mashan. Wang (1994) had already established Qianxi and Ziyun as varieties of Guiyang. This classification is repeated in Wu and Yang (2010):

Chuanqiandian cluster (川黔滇 Chuānqiándiān)
A-Hmao (滇东北 Diāndōngběi)
Guiyang Miao (贵阳 Guìyáng)
Huishui Miao (惠水 Huìshuǐ)
Mashan Miao (麻山 Máshān)
A-Hmyo (罗泊河 Luóbóhé)
Gejia (重安江 Chóng'ānjiāng)
Pingtang Miao (平塘 Píngtáng)

The varieties analyzed by Li Yunbing (2000) are:

Guiyang Miao
 (also called Jiucai Miao 韭菜苗) in Hongyan, Baiyun township, Ziyun County 紫云县白云乡红岩寨; 4,000 speaker
 in Tieshi township, Qianxi County 黔西县铁石苗族彝族乡
Pingtang Miao
 in Jiatong township, Pingtang County 平塘县甲桐乡 (currently Kaluo 卡罗乡); 11,000 speakers
 in Xinmin township, Dushan County 独山县新民乡; 4,000+ speakers
 (also called Red Miao 红苗) in Pingyan, Luodian County 罗甸县平岩乡; 6,000 speakers
 in Youmai, Wangmo County 望谟县油迈乡; 3,000 speakers
Mashan Miao
 (also called Cotton Miao 棉花苗; Bouyei: ) in Dalang, Ziyun County 紫云县打狼乡; 4,000 speakers
 in Moyin, Luodian County 罗甸县模引乡; 4,000+ speakers

Li (2000) considers Raojia () of Heba 河坝, Majiang County, to be a separate dialect of Hmu (East Hmongic). It has 5,000 speakers in Majiang County, and 10,000 speakers total.

Bu–Nao was not included because the speakers are classified by the Chinese government as ethnically Yao rather than Miao.

Matisoff (2001)
James Matisoff outlined the following in 2001. Not all languages are necessarily listed.

Western Hmong
 Libo Miao (= ?, maybe Bu–Nao)
 Weining Miao (= A-Hmao / Large Flowery Miao?)
 Guangshun Miao (Yi Miao) (= ?)
 Sichuan–Guizhou–Yunnan (= Chuanqiandian cluster)
 Petchabun (White Hmong)
 Green Hmong (Blue Hmong)
 Suyong Miao (Magpie Miao)
 Chuan Miao (Western Sichuan Miao)
 Huajie Miao (= ?)

Mortensen (2004)
David Mortensen argues for the following classification of Western Hmongic based on shared tonal innovations, including tone sandhi. Pingtang, Luobohe, and Chong'anjiang are not addressed.Western HmongicGuiyang-Huishui
Guiyang
Baituo  (in Qingyan , Huaxi District)
Tieshi 
Zhongba 
Huishui
Jiading 
Core Western Hmongic
Mashan
Jiaotuo  (in Zongdi , Ziyun County), Shuijingping 
Xinzhai 
Far Western Hmongic
A-Hmao (Diandongbei)
Western
Eastern
Hmong (Chuanqiandian)

Ratliff (2010)
Martha Ratliff includes three languages specifically:
Hmong (Chuanqiandian in the narrow sense)
A-Hmao (Big Flowery Miao)
Bunu

The last contradicts Matisoff (2001), who had posited a Bunu branch of Hmongic with Bu–Nao in it, but recapitulates Strecker (1987). The other Western varieties are not addressed, though some are included in her reconstruction of Proto-Hmong–Mien.

Castro & Gu (2010):  Wenshan
Andy Castro and Gu Chawen divide the Hmong dialects of Wenshan Prefecture, Yunnan, into four subdivisions, listed from east to west.

  (, 'Lopsided Miao'; most divergent)
  (, , 'White Miao')
 Shib-Nzhuab (, 'Green Miao')
 
 
 Soud-Bes-Buak (, 'Flowery Miao')
 
 
 

The dialects given above are named after the groups they are spoken by.

Castro, Flaming & Luo (2012): Honghe
Castro, Flaming & Luo (2012) found that there are 4 different West Hmongic languages in Honghe Prefecture, Yunnan.

 Northern Hua Miao
 Southern Hua Miao
 White Miao
 Sinicised Miao

Castro, Flaming & Luo (2012) propose the following classification for the Western Miao dialects of southeastern Yunnan, which is based on Michael Johnson's 1998 classification of Western Miao dialects.Western Miao [Hmong]' Sinicised Miao

Writing
The Miao languages were traditionally written with various adaptations of Chinese characters. Around 1905, Sam Pollard introduced a Romanized script for the A-Hmao language, and this came to be used for Hmong Daw (Chuanqiandian) as well. In the United States, the Romanized Popular Alphabet is often used for White and Green Hmong (also Chuanqiandian).

In China, pinyin-based Latin alphabets have been devised for Chuanqiandian—specifically the variety of Dananshan (), Yanzikou Town (), Bijie—and A-Hmao. Wu and Yang (2010) report attempts at writing Mashan in 1985 and an improvement by them; they recommend that standards should be developed for each of the six other primary varieties of West Hmongic.
