What are the genres and contents of poetry?

From the genre of poetry, it can be divided into two categories: ancient poetry and new poetry. Ancient poems can be divided into modern poems and ancient poems (ancient style), and modern poems can be divided into metrical poems (metrical poems [five-character metrical poems, seven-character metrical poems], quatrains [five-character quatrains, seven-character quatrains]), words and songs. New poems include free poems (vernacular poems produced since the May 4th Movement), prose poems (lyric poems expressed in prose) and folk songs (poems circulated by the people and created collectively).
