What is the name of each sentence in China's ancient poems? What is the name of each of the four common ancient poems?

1, eight lines of metrical poem * * *, one sentence for every two lines, the first sentence is the first couplet, the second sentence is the parallel couplet, the third sentence is the neck couplet, and the fourth sentence is the tail couplet. Among them, parallel couplets and neck couplets require that they must be seated accordingly.

2. The difference between regular poems and quatrains is mainly in the number of words, four quatrains and eight quatrains. Quatrains, also called "truncated sentences", generally rhyme as one, two or four sentences (except special ones). The quatrains may or may not be antagonistic. And the neck couplet of metrical poetry must be a antithesis. Both metrical poems and quatrains require even tone, and metrical poems with more than eight sentences are called rhythm.
