What nationality does Yao belong to?

Yao is an ancient ethnic group in China, with simple and tenacious folk customs and a large population living in mountainous areas, so there is a saying that "there is no mountain without Yao". Yao people call themselves Mian, Jinmen, Bunu, Bingduoyou, Heiyoumeng and Lajia. The Yao population in China is 2.853 million (20 10), including Guangxi (17 10), Hunan (705,000), Guangdong (203,000), Yunnan (19) and Guizhou (44,000). Jiangyong County, Yongzhou City, Hunan Province, has a population of 63.2%, which is the county with the highest proportion and density of Yao population in China, but no Yao autonomous county has been established so far. Jianghua County, Hunan Province has a population of more than 250,000, ranking first in the country, and is known as the Yao Capital of China. Yao people live across borders and are widely distributed in Vietnam, Laos and northern Thailand. It is one of the 54 ethnic groups in Vietnam. With a population of more than 800,000, Yao nationality in Vietnam is the ninth largest ethnic group in Vietnam. In the era when Southeast Asian countries rejected China, some of them migrated across the ocean to the United States, France, Canada, Mexico and other places. There are many branches of Yao nationality, with great differences in languages, such as Burmese, Bunu and Raja. 1982, experts from Minzu University of China created Yao language in the form of 26 Latin letters, and spelled Mian language with Latin letters. Chinese is widely used now. Many people can speak Zhuang and Miao at the same time. Historically, Yao and Miao have a close blood relationship, which originated from the "Wuling Man" tribe in the Qin and Han Dynasties. Yao people have high attainments in longevity, beauty and medical skills. Yao medicine has been well received by the majority of patients in the treatment of cancer, gynecological diseases, rheumatism, lupus erythematosus, traumatic fracture and snake bite. Most Yao people believe in Taoism and witchcraft, and a few Yao people in mountainous areas are also good at Maoshan witchcraft. Yao nationality in a broad sense: both Yao nationality and She nationality have totems and four surnames: Pan, Lan, Lei and Zhong. These four surnames are the same, and some words are the same. In addition, she people have also called themselves Shan Yao, Yao Jia and Ren Yao since ancient times.
