Every household in China will post Spring Festival couplets every Spring Festival. The origin of Spring Festival couplets should also start from Fu Tao. According to ancient legend, there is a big peach tree in Dushuo Mountain in the East China Sea. There is a tea tree and a gloomy Er Shen and Er Shen under the peach tree. In case of trouble, they will tie it up and feed it to the tiger. Later, during the Spring Festival in China, in order to drive away ghosts, they drew these two statues on the mahogany board, which is Fu Tao.
Spring Festival couplets are a new style originated from ancient parallel prose in China, which draws lessons from the traditional literary form of China's poems. It is different from ancient parallel prose and poetry, and it is a unique independent style. Although the antithetical couplets in regular poems or parallel prose are often wonderful couplets, they can only be called couplets if they exist independently of regular poems or parallel prose.
