Couplets, also known as couplets, are antithetical sentences written on paper, cloth or engraved on bamboo, wood and columns. They are concise, neat and even, and they are a unique art form of Chinese language. According to legend, couplets originated from Meng Changjun, the master of Shu after the Five Dynasties. It is a cultural treasure of the Chinese nation. The couplets hung during the Spring Festival are called Spring Festival couplets.

Couplets, also known as couplets, dual plays, door pairs, spring stickers, spring couplets, couplets and peach symbols, are a kind of dual literature and originated from peach symbols. Couplets are a national style written by using the characteristics of Chinese characters. Generally, there is no need to rhyme (only couplets in regular poems need to rhyme). Couplets can be roughly divided into poetry couplets and prose couplets. The format of couplets is strict and the part of speech is relative. Traditional couplets are connected in form, with the same content, harmonious tone and rigorous antithesis.

With the rise of poetry in the Tang Dynasty, prose couplets were excluded. Prose couplets are generally informal, straightforward, and do not avoid repetition. They do not overemphasize the equivalence of parts of speech without losing duality.

Spring Festival couplets have a long history. It is said that they originated from Meng Chang, the master of Shu after the Five Dynasties. On the peach symbol board at the door of his bedroom, he wrote: "Come in the New Year, the first day is Changchun", which means "Write the peach symbol" (see Shu Lang). This is the earliest couplet in China and the earliest Spring Festival couplets.

The second part is to confront, agree with or refute foreign objects. The meaning and depth of antithesis cannot be said without prose couplets.

Features:

First, the upper and lower couplets have equal words and the same structure. In addition to deliberately leaving the position of a word to achieve a certain effect, the number of words in the upper and lower parts must be the same.

Second, the corresponding parts of speech are the same. Verb to verb, adjective to adjective, quantifier to quantifier, adverb to adverb and relative words must be in relative positions.

Third, it is necessary to have a clear hierarchy and a harmonious tone. According to the rhyme, the upper rhyme should be wrinkled and the lower rhyme should be flat, which is called "wrinkled flat".

Fourth, the rhythm corresponds, that is, the places where the upper and lower links stop must be consistent.
