There are 26 ethnic minorities in Yunnan, namely Yi, Bai, Hani, Dai, Zhuang, Miao, Hui, Lisu, Lahu, Wa, Naxi, Yao, Jingpo, Tibetan, Bulang, Buyi, Achang, Pumi, Mongolian and Nu. Among them, 15 ethnic groups are unique to Yunnan, namely Bai, Hani, Dai, Lisu, Lahu, Wa, Naxi, Jingpo, Bulang, Pumi, Achang, Nu, Jino, De 'ang and Dulong. Ethnic minorities refer to ethnic groups other than the main ethnic groups in multi-ethnic countries. In People's Republic of China (PRC), except the Han nationality, the other 55 legal ethnic groups are all ethnic minorities. After the founding of New China, the Party and the government organized forces to distinguish between national names and nationalities in order to formulate and implement national achievements and realize the equality of rights of all ethnic groups. This work is a national appraisal. Through their efforts, scientists have made clear the basic composition of China's ethnic family and identified 56 ethnic groups. The smooth progress of ethnic identification has laid a foundation for ethnic work.
