Hlai languages

The Hlai languages are a primary branch of the Kra–Dai language family spoken in the mountains of central and south-central Hainan in China by the Hlai people, not to be confused with the colloquial name for the Leizhou branch of Min Chinese. They include Cun, whose speakers are ethnically distinct. A quarter of Hlai speakers are monolingual. None of the Hlai languages had a writing system until the 1950s, when the Latin script was adopted for Ha.
