Li Sao is the longest and most attractive lyric poem in classical literature, the crystallization of Qu Yuan's patriotism and loyalty to the monarch, and a romantic masterpiece handed down from generation to generation. ? The language form of Li Sao has a creative development in the history of development. Most of the poems before Lisao were in the form of The Book of Songs, with four characters as the mainstay, neat and heavy. However, Li Sao dared to innovate and boldly broke through this form, forming a new style poem "Chu Ci". Li Sao is basically a chapter and four sentences, each sentence has uneven words, most of which are even sentences, forming the characteristics of both scattered and neat.
