Lisu people belong to the South Asian type of Mongolian race, and their national language belongs to the Yi branch of the Tibeto-Burman language family of Sino-Tibetan language family. Their writing is divided into new Lisu language and ancient Lisu language, and they generally believe in primitive religion. Lisu nationality originated from ancient frontier ethnic groups and has a certain relationship with Yi nationality. They are mainly distributed in Nujiang River and Enmeikai River (a tributary of Irrawaddy River), namely the border areas of Yunnan, China, Tibet and Kachin State of Myanmar, while the rest are scattered in other parts of Yunnan, China, northeastern India and the border areas of Thailand and Myanmar.

Lisu is his name as well as his own. This name first appeared in the works of the Tang Dynasty. At that time, Fan Chuo called chestnuts in Manchu books, which was considered as an inseparable part of Manchu at that time. It is closely related to Yi and Naxi nationalities in ethnic origin. In the Ming Dynasty, Lisu people were still regarded as a branch of Luoluo. In the Ming Dynasty, Jingtai's "Yunnan Tujing" was written by Li Su.

Festival custom

Lisu people call the annual festival "generalized". Before the founding of New China, the Lisu people in Nujiang mainly decided the time of Chinese New Year by observing phenology, so there was no unified date, but it was usually from the fifth day of December in the summer calendar to the tenth day of the first month of the following year, that is, the cherry blossom season and festival period. In order to pray for good weather and good harvests in the coming year.

Every family should put some indica rice bran in the first mortar on peach trees, pear trees and other fruit trees. In some places, a small bowl is served to dogs before eating. It is said that this is a reward for dogs to bring seeds to the world. On the first day of the festival, young men and women from all over the country will dress up and gather in public places in their villages-playing games, holding crossbows, dancing, singing and other activities.
