It's almost time for every household to post new Spring Festival couplets, but it's not easy to post couplets well, especially to distinguish the upper and lower couplets accurately. The symmetry of format, phonology and word meaning is achieved, and such symmetry should be formed. The upper and lower couplets must have the same part of speech, relative content and level and level.

As early as the Warring States period more than two thousand years ago, the "peach stalk", also known as "peach symbol", was hung on the Spring Festival in the Central Plains. In the Qing Dynasty, Fucha Dunchong's "Yanjing Years" recorded: "The Spring Festival couplets are also Taofu." The relationship between Spring Festival couplets and peach symbols can also be seen from the traditional Spring Festival couplets, such as "firecrackers get rid of the old, peach symbols are renewed" and Wang Anshi's poem "Thousands of families always exchange new peaches for old symbols".

What is a peach charm? According to Huai Nan Zi, the names of shentu and Yu Lei are written on the mahogany board and hung on both sides of the door. Such a couplet is a peach symbol. In the Five Dynasties, more than 700 years AD, Meng Fang, the queen of Shu, wrote, "New Year's Qing Yu, JiajieNo. Changchun." It is recorded as the earliest Spring Festival couplets in China. Since Meng Chang wrote the Taofu, scholars followed suit and regarded the Spring Festival couplets as elegant things, so the wind of writing Spring Festival couplets gradually spread.

In the Song Dynasty, couplets were not only inscribed on peach symbols, but also used on the pillars, which was later called "couplets". It was not until the Ming Dynasty that "Taofu" was really called "Spring Festival couplets". According to Chen Yunzhan, a scholar in the Ming Dynasty, "When a public official or a scholar is at home, a Spring Festival couplets must be added at the door, so that the emperor can walk out." The emperor's advocacy made the Spring Festival couplets increasingly prosperous and formed a fashion that has never wavered so far.
