What are the classifications of ancient poetry?

From the metrical point of view, ancient poetry can be divided into "ancient poetry" and "modern poetry". Ancient poetry is also called "ancient poetry" or "ancient style", and "modern poetry" is also called "modern poetry". Generally speaking, with the Tang Dynasty as the boundary, the poems before the Tang Dynasty are "ancient poems", and the later poems are "modern poems", but sometimes there are exceptions. Ancient poems include ancient poems (poems before Tang Dynasty), songs of Chu and Yuefu poems. Classical poetry does not talk about antithesis and rhymes freely. Modern poetry is a kind of metrical poetry formed in the Tang Dynasty, which is divided into two types. One is quatrains, including five-character quatrains and seven-character quatrains, and one * * * has four sentences; One kind is regular poetry, including five-character regular poetry and seven-character regular poetry, with one * * * eight sentences. Among them, Wuyan is a five-character poem and Seven-character poem is a seven-character poem. Modern poetry, especially metrical poetry, has strict rules on the number of words, sentences, levels and rhymes.

Judging from the content of poetry, it can be divided into farewell poems, frontier poems, pastoral poems, nostalgic poems, object-chanting poems, allegorical poems, in my heart forever poems, traveling poems and so on.

From the form of expression, it can be divided into narrative poems, lyric poems and philosophical poems.
