Because southerners pay more attention to wearing single clothes, and most of them are light colors that are not easy to absorb heat, the materials used by southern ethnic groups are mostly cotton cloth, especially the materials of many ethnic minorities in the south, mostly self-woven linen and homespun. This situation was most obvious in ancient times. Skirts are popular in many places in the south, especially in some ethnic minorities, and they are indispensable. These are the essence of southern costumes. Moreover, because there are many mosquitoes in the south, the practical function of long skirts is to protect the legs from being scratched by grass leaves and prevent mosquito bites.
