First, before the appearance of new poetry, the meaning of ci fu, ancient customs, laws and rhymes since the Book of Songs was similar to that of "classical poetry". Second, it refers to the poetry works created by modern people in the form of classical poetry after the birth of new poetry. From 1950s to 1960s, people from all walks of life also wrote old-style poems.

Old poems include ancient poems and modern poems.
