What are the four parts of the quatrains called?

The four parts of quatrains are the first couplet, the parallel couplet, the neck couplet and the tail couplet. Among them, the first couplet is also called starting couplet, and the last couplet is also called tying couplet. Among them, "neck connection" and "parallel connection" should be dual.

Quatrains, also called truncated sentences, broken sentences and quatrains, are short and pithy. It is a popular genre of Chinese poetry in the Tang Dynasty and belongs to a form of modern poetry. The word quatrains first appeared in the Qi and Liang Dynasties in the Southern Dynasties.

There are different interpretations of it, and some people think that the "half-cutting method" is convenient for singing. Quatrains are composed of four sentences, which are divided into quatrains and archaic quatrains, among which quatrains have strict metrical requirements. Common quatrains include five-character quatrains and seven-character quatrains, while six-character quatrains are rare.

The quatrains originated from the short chapters of Yuefu in the Han, Wei and Six Dynasties, and their names may come from the "couplets" written by literati in the Six Dynasties. According to the literature, there was a custom of writing poems in the banquets of literati in the Six Dynasties, and each person wrote four sentences and five words to synthesize a whole poem. If you cut off what everyone has done and do a separate article, it is called "unique skill", and the name of the quatrains comes from this.

The absolutely unique concept of four sentences is naturally formed. Since the Book of Songs, most poems have taken four sentences as a paragraph. The poems in The Book of Songs are mostly four words and four sentences, which the ancients called "a chapter". During the Han and Wei Dynasties, there were very few four-sentence poems as a whole, so it is not necessary to define four-sentence poems as poetic nouns, that is to say, four-sentence poems did not become the standard. However, in a long poem, the creative method of four sentences is naturally formed. After the Jin and Song Dynasties, due to the influence of folk songs, poets liked to imitate four folk songs, and a large number of small poems with five words and four sentences appeared. After the Qi and Liang Dynasties, four sentences and one absolutely became the norm of poetry and were given the name "absolutely". The "broken sentences", "short sentences" and "quatrains" in the Southern Dynasties are all used to refer to poems with five words and four sentences.
