Old-style poems include ancient poems and modern poems.
Classical poetry, also known as classical poetry, is not restricted by strict metrical rules. There are four words, five words and seven words (words are words). For example, Du Fu's Li Shihao is a five-character ancient poem.
Modern poetry, also known as modern poetry, includes metrical poems and quatrains, with strict metrical patterns and five-character and seven-character sentence patterns. The difference between metrical poems and quatrains mainly lies in the number of sentences. Four-line quatrains can be correct or incorrect. Eight-line metrical poems must be opposed to each other, except for metrical poems with more than eight lines.
New poetry refers to vernacular poetry produced since the May 4th Movement, also called modern poetry, which is relative to traditional poetry (old poetry). Written in vernacular Chinese, the meter is not as strict as the old-style poem, but the lines have a certain rhythm, and the last word of even lines generally rhymes. Free verse in new poetry is more free, and some of them don't even rhyme or punctuate.
Although some poems are created in modern times, their genres still follow the old ones. For example, Chen Yi's "meiling three chapters" expresses revolutionary feelings in the form of quatrains, but it is still an old-fashioned poem in form.
