Yi people, formerly known as "ancient Yi people", are named after the "Southwest Yi people" recorded in Hanshu (collectively referred to as southwest ethnic minorities). 1 call yourself Ni (? ), the pronunciation of "Ni" in ancient Chinese is foreign, so it is often called "Yi" in Chinese records. 1956, during the period of getting rid of ethnic discrimination in the old society, Yi representatives sent people to Beijing to pay a visit to Chairman Mao. Chairman Mao understood the situation, listened to opinions and put forward suggestions. Because the name of "Yi people" is derogatory (barbarians), he changed "Yi" to "Yi", which means there are "rice" and "silk" under the house. Yi people are the sixth largest minority in China. 1 They mainly live in Yunnan, Sichuan and Guizhou provinces in the southwest of China, and the rest are scattered in other provinces of China and abroad. Yi nationality is an important member of the Chinese nation. The total population is about 9 million, the registered population in China is 8,765,438+4,393 (2010), and there are nearly one million Southeast Asian countries such as Viet Nam, Laos, Myanmar and Thailand. There are many branches of the Yi people, such as Sunuo, Niesu, Nasu, Naisu, Nizu, Wu Luo, Axipo, Ashi, Sani and Nipo, but they are not all self-proclaimed in the national sense, such as Wu Luo, Sani, Azhe and Nipo. In the Yi language context, the meanings are exactly the same, and they all come from "you" [1]. Generally speaking, the word "Nicuo" () can cover all branches, and Sunuo is the largest branch of the Yi people, mainly distributed in Liangshan, Sichuan. Yi languages in some different places can't communicate directly, but the same vocabulary is over 60% and the grammatical structure is the same. After a brief acquaintance, the traditional festival of Yi people is Torch Festival.
