Dai people 傣族
Dai people 傣族, numbered about 1.3 million, are one of several ethnic groups living in the Xishuangbanna Dai Autonomous Prefecture 西双版纳州 and the Dehong Dai and Jingpo Autonomous Prefecture (both in southern Yunnan, China), but by extension can apply to groups in Laos, Vietnam, Thailand, and Burma when Dai is used to mean specifically Tai Lue, Chinese Shan or even Tai in general. The Dai people form one of the 56 ethnic groups officially recognized by the People's Republic of China, and are closely related to the Lao and Thai people who form a majority in Laos and Thailand. Originally, the Tai, or Dai, lived closely together in modern Yunnan Province until political chaos and wars in the north at the end of the Tang and Song Dynasty and various nomadic peoples prompted some to move further south into modern Laos then Thailand.
The two main languages of the Dai, aside from speaking Mandarin and writing Chinese, are Dai Lü (Sibsongbanna Dai) and Dai Nüa (Daihong Dai). The written language was derived from Devanagari and differs from region to region which belong to the Zhuang-Dai branch of the Zhuang-Dong group of Sino-Tibetan languages. The Dai peoples follow their traditional religion as well as Theravadin Buddhism, and maintain similar customs and festivals (such as the Sankrant) to the other Tai-speaking peoples. They are among the few natives groups in China who nominally practice the Theravada school of Buddhism. The Dai are primarily farmers so they mostly live close to the water in low-latitude and low-altitude areas, where the climate is warm and humid with plenty of rain
