Poetry, a difficult word to define, may be controversial, or it may never be mentioned. First of all, poetry may refer to the Book of Songs, but now it can refer to poetry. But in ancient times, it was also said that chorus was called poetry, and chorus was called song, which meant that songs could be sung and poems could only be read. This definition is actually a form different from words, songs and songs.
Poetry, in fact, is not well defined. It is about the combination of poetry (including ancient poetry and modern poetry) and words. And ancient poetry, just add a deadline, ancient poetry.
