The Hlai, also known as Li or Lizu, are a Kra–Dai-speaking ethnic group, one of the 56 ethnic groups officially recognized by the People's Republic of China. The vast majority live off the southern coast of China on Hainan Island, where they are the largest minority ethnic group. Divided into the five branches of the Qi (Gei), Ha, Run (Zwn), Sai (Tai, Jiamao) and Meifu (Moifau), the Hlai have their own distinctive culture and customs.
