Couplets are a national style written by using the characteristics of Chinese characters, and generally do not need to rhyme (only the antithetical sentences in regular poems need to rhyme).
As a custom, couplets are an important part of China traditional culture. In 25, China the State Council listed the custom of couplets as the first batch of national intangible cultural heritage list. 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.
