Hakka, a special and little-known ethnic group in Hainan, is a branch of the Chinese Hakka system that has been neglected. They are far from the mainland, and they are rarely mentioned. The relatively closed environment has allowed the Central Plains culture to be completely preserved. After that, it has formed a special change with the ethnic minorities such as Li Miao. However, this unique traditional culture is now fading away in the erosion of modern civilization.
