Kra–Dai-speaking peoples
The term Kra–Dai peoples or Kra–Dai-speaking peoples refers collectively to the ethnic groups of southern China and Southeast Asia, stretching from Hainan to Northeast India and from southern Sichuan to Laos, Thailand and parts of Vietnam, who not only speak languages belonging to the Kra–Dai language family, but also share similar traditions, culture and ancestry. == Origin == Chamberlain (2016) proposes that the Kra–Dai language family was formed as early as the 12th century BCE in the middle of the Yangtze basin, coinciding roughly with the establishment of the state of Chu and the beginning of the Zhou dynasty.
