The poetry genre characterized by a large number of Xi characters is? Also known as?

"Songs of Chu": It is my country's first collection of romantic poetry, edited by Liu Xiang, a scholar of the Western Han Dynasty. Because the form of the poem was processed on the basis of Chu folk songs, and the poem quoted a large number of local customs, products and dialect vocabulary of the Chu region, it was called "Chu Ci". "Chu Ci" is mainly the work of Qu Yuan, the great patriotic poet of our country. His representative work is "Li Sao". Therefore, later generations also called "Chu Ci" as "Song style". At the end of the Western Han Dynasty, Liu Xiang collected the works of Qu Yuan, Song Yu and others and compiled them into a collection. "Chu Ci" is the source of my country's positive romantic poetry creation.
