There are four ethnic groups, Li Han and Miao Hui, living in Hainan Island. Their long-term cultural blending and infiltration have special manifestations in the lyrics, sentence patterns and tunes of folk songs. These folk songs with strong local ethnic characteristics have brought endless vitality to the increasingly active original music, which cannot but be attributed to the richness and diversity of Hainan folk songs. The soul work "I Made a Hat to Send to the Red Army" of the famous modern ballet "Red women soldiers" is based on the adaptation of the Li folk song "Wuzhishan and Five Rivers", and is created by using the composition techniques such as transposition and variation. Similarly, the powerful Legato of Red women soldiers also benefited from the inspiration of Wuzhishan folk songs, such as "The People's Liberation Army Came to Qilizhai" by Chen Guangzhou and Xie Qing's.
