What are the language styles of classical poetry?

Graceful, solemn and unrestrained, this should be the genre of poetry, such as pastoral poetry, farewell poetry, writing scenery, containing things, and so on

The original poems originated from ballads and were called new poems, such as The Book of Songs and Songs of the South.

The Han dynasty developed into Yuefu poetry, followed by five words. Poetry can't be sung at this time, so there are words, and then there are songs.

Therefore, Yuefu, poetry, ci and qu should all belong to poetry.
