Couplets, also known as antithesis, antithesis, spring stickers, Spring Festival couplets, couplets, Taofu and couplets (named after the pillars hanging in halls and houses in ancient times), are a kind of dual literature, which originated from Taofu. It is a antithetical sentence written on paper, cloth or engraved on bamboo, wood and columns. It is a unique art form of Chinese, concise and profound, neat and even, with the same number of words and the same structure.

According to legend, couplets originated from Meng Chang, a master of Shu after the Five Dynasties. It is a treasure of Han traditional culture. Spring Festival couplets are called Spring Festival couplets, funeral couplets are called elegiac couplets, and wedding couplets are called violet couplets. Couplets are a national style written by using the characteristics of Chinese characters, and generally do not need to rhyme (only the antitheses in the rhyme need to rhyme). Couplets can be roughly divided into poetry couplets and prose couplets.

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 Changjun, the master of Shu after the Five Dynasties. He wrote an inscription on the peach symbol on the door panel of the dormitory: "When the New Year arrives, the number of festivals will be in Changchun", which means the words "Write the peach symbol" (see Shu Lang). This is the earliest couplet in China and the first Spring Festival couplet.

As a custom, couplets are an important part of Han traditional culture. In 2005, the custom of couplets was listed in the first batch of national intangible cultural heritage in the State Council, China. The custom of couplets is passed down and spread in Chinese-speaking areas and ethnic groups with cultural origins of Chinese characters, which is of great value for promoting Chinese culture.
