Thailand is a multi-ethnic country with more than 30 nationalities. The main ethnic groups are Thais, as well as China people who believe in Buddhism and Lansi people of Yi nationality. In addition, in modern times, Thailand became an ally of the United States. Historically, the relationship with Britain and the United States and other western countries is serious, and now it is almost inseparable. In short, most of them may be like some ethnic groups in Yunnan Province, because Thai belongs to Zhuang-Dong language family in China. Guangxi Zhuang people, Yunnan Dai people, Dong people and Lao people should be more like them, with obvious eyes. However, the history of Thai-Chinese mixed blood is too long. They have been engaged in immigration trade since the Yuan Dynasty. If they want to see the original inhabitants, they must go to the tribe. There are too many Chinese in Chiang Mai, Bangkok and many places in central China. Many people may be one-eighth or one-sixteenth Chinese, such as the royal family and the king of Thailand.
