Ancient poetry is written according to the style of ancient poetry, which is divided into four-character ancient poetry, five-character ancient poetry and seven-character ancient poetry. Modern poetry is divided into quatrains and metrical poems. The difference between metrical poems and quatrains mainly lies in the number of sentences. There are four quatrains and eight rhyming poems.
