Bu–Nao languages
Hmongic language cluster of China
The Bu–Nao or Bunu languages are a Hmongic (Miao) language branch spoken in Guangxi, Yunnan, and Guizhou in China. Its speakers are officially classified as ethnic Yao and speak Hmongic languages. The branch consists of three languages, which are Bunu (or Bunu proper), Baonao (Nao Klao), and Numao. The term Bu–Nao is a portmanteau of Bunu and Nao Klao.
Classification
Speakers of Bu–Nao languages are officially classified as Yao people by the Chinese government, although they speak Hmongic languages rather than Mienic languages. Strecker (1987) had classified Bunu proper as a Western (Chuanqiandian) Hmongic language, and the other "Bunu" languages—Younuo (Yuno), Wunai (Hm Nai), and Jiongnai (Kiong Nai)—as distinct branches of Hmongic. Matisoff (2001) grouped all of these together in a Bunu branch of Hmongic (that is, outside Western Hmongic). Ratliff (2010) classified Bunu within Western Hmongic and moved Jiongnai to its own peripheral branch of Hmongic. Wang & Deng (2003) classify the Bu–Nao languages as a cousin branch of Western Hmongic, and Jiongnai and Younuo as independent branches.
Language varieties
Bu–Nao language varieties are spoken by a total of 390,000 speakers.

Why this record matters
“Bu–Nao languages” is worth following because a concise public description often conceals a longer documentary argument. Here, languages, Hmongic and language provides the most credible route into that argument.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Mar 23, 2026. The linked authority identifier is Q56411. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1987, 2001, 2010 and 2003.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
