How many people are there in the Yao people?

The Yao people are an ancient ethnic group in China. Their folk customs are simple and strong, and most of the people live in mountainous areas. Therefore, there is a saying that "there is no Yao without mountains". The Yao people call themselves "Mian", "Kinmen", "Bunu", "Bingduoyou", "Heiyoumeng", "Lajia", etc. China's Yao population is 2.853 million (2010), including Guangxi (1.71 million), Hunan (705,000), Guangdong (203,000), Yunnan (190,000), and Guizhou (44,000). The Yao population in Jiangyong County, Yongzhou City, Hunan Province accounts for 63.2%, making it the county with the highest Yao population proportion and density in the country. However, a Yao autonomous county has not yet been established. The Yao population in Jianghua County, Hunan Province is more than 250,000, the highest in the country. It is known as the Yaodu of China. The Yao people live across borders and are also widely distributed in Vietnam, Laos, and northern Thailand. It is one of the 54 ethnic groups in Vietnam. The Yao ethnic group in Vietnam has a population of more than 800,000 and is the ninth largest ethnic group in Vietnam. During the era when Southeast Asian countries were anti-Chinese, some of them immigrated across the ocean to the United States, France, Canada, Mexico and other places. The Yao people have many branches and their languages ??vary widely, including Mian, Bunu, Lajia and other languages. In 1982, experts from the Minzu University of China created Yao script in the form of 26 Latin letters, and used Latin letters to spell Mian language. Chinese is now commonly spoken. Many people can speak Zhuang, Miao and other languages ??at the same time. Historically, the Yao and Miao people have close kinship relations and originate from the "Wuling Man" tribe in the Qin and Han Dynasties. The Yao people have extremely high attainments in longevity, beauty and medical skills. Yao medicine has always been highly praised by patients for its effectiveness in treating cancer, gynecological diseases, rheumatism, lupus erythematosus, fractures due to injuries, snake bites and other diseases. Most of the Yao people believe in Taoism and witchcraft. A very small number of Yao people in a few mountainous areas are also good at Maoshan witchcraft. The Yao people in the broad sense: including the Yao people and the She people, all have the Panwang totem and the four surnames Pan, Lan, Lei and Zhong. They are the same, and some words are the same. Since ancient times, the She people have also called themselves Shan Yao, Yao family, Yao people, etc.
