Couplets, one of the traditional cultures in China, also called couplets or couplets, are antithetical sentences written on paper, cloth or engraved on bamboo, wood and columns. The antithesis of couplets is neat and even, which is a unique artistic form of Chinese language. Couplets are the treasures of China traditional culture.

As a custom, couplets are an important part of China 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.
