The traditional spinning, dyeing, weaving and embroidering techniques of Li nationality are formed by combining the cotton spinning techniques of Li nationality, hemp textile processing and Valerian dyeing techniques. Before the Song and Yuan Dynasties, the textile technology of Li nationality was ahead of the Central Plains for more than 1 years, which made a special contribution to the development of cotton textile industry in China. The clothing of Li nationality is the crystallization of the traditional cotton textile technology of Li nationality, which has typical national characteristics. The clothing of each dialect used to be an important symbol to distinguish different blood groups and tribal groups in history. Li brocade patterns are rich and colorful, with more than 16 kinds. Li nationality's traditional cotton textile technology has many remarkable characteristics, which, in a nutshell, are mainly manifested in the living fossil of culture, outstanding historical contribution, distinctive nationality, typical original ecology, inherited family nature and so on. At present, except for a few people who know some brocade techniques and embroidery, few young people have learned the spinning and dyeing techniques, and the cotton textile techniques that have been passed down for thousands of years are in danger of being lost. 7. Li bark cloth making skills Project category: Main features and values of handcraft skills: strong evidence for the development of human clothing from non-woven fabrics to woven fabrics. Bark cloth has a very long history. Bark cloth in Hainan Island exists about 4 years ago. Bark cloth itself is perishable, and it is difficult to be preserved as historical evidence for a long time, but the stone racket, one of the tools for making bark cloth, can be preserved. According to archaeologists' research, Hainan bark cloth stone pats have been collected from time to time by farmers in Li settlements, and some museums also have collections. Experts in Hainan Province found that some people can identify trees that can make bark cloth, and some families can also make bark cloth, clothes and hats in the dialect areas such as Li Run dialect and Ha dialect.

Li nationality's skill of drilling wood for fire project category: main features and values of manual skills: Li nationality's drilling wood for fire is one of all kinds of manual fire-making techniques in ancient times, with distinctive regional characteristics.

Li's wood-drilling and fire-taking tools are composed of two parts, one is the fire-drilling board, and the other is the drill rod and bow wood. Only when they cooperate can the fire be taken out. It is of archaeological and historical value for Li people to drill wood for fire. The media used in wood drilling for fire, that is, flammable core wool, banana root fiber, wood cotton wool and so on, are organic substances, which are not easy to preserve because of their age. As a cultural relic, the drill board, drill rod or bow wood is a kind of dead fossil, which can't speak by itself. It is difficult to explain the process of drilling wood to make fire by these materials alone, so we can only turn to the help of ethnology related materials as "living fossils". 9. Category of the March 3rd Festival of the Li nationality: Main features and values of folk customs: It is a concentrated expression of the overall folk customs of the Li nationality, such as production, life and entertainment, and a window for the world to understand the culture and history of the Li nationality.
