Putting up Spring Festival couplets is the first thing people do to celebrate the Spring Festival. Whenever the Spring Festival approaches, every household will put brand-new Spring Festival couplets on both sides of the gate, with black characters on a red background, which is steady and bright. Express the family's best wishes for the new year, such as "six animals are prosperous and the grain is abundant". Some Spring Festival couplets also focus on reflecting different "happiness views" of different industries and families. Therefore, it is undoubtedly a meaningful way to observe folk customs to carefully study the Spring Festival couplets posted by people during the Spring Festival.

Spring Festival couplets originated in Fu Tao (rectangular red boards were hung on both sides of the gate in the Zhou Dynasty). According to the Book of Rites, the peach symbol is six inches long and three inches wide, and the names of ghosts and gods Shen Tu and Lei Yu are written on the mahogany board. "On the first day of the first month, I made a peach symbol for this family and named it Xianmu. All ghosts are afraid of it." Therefore, the Qing Dynasty's "Yanjing Year" records: "Spring Festival couplets, that is, Fu Tao." During the Five Dynasties and Ten Kingdoms period, in the court, someone inscribed couplets on peach symbols. The History of Shu Family in Song Dynasty said: Meng Chang, the master of the later Shu Dynasty, ordered Zhang Xun, a bachelor, to write a poem on the mahogany board, "Because it is not working, it pretends to write a cloud:' Welcome the New Year, celebrate Changchun'". This is China's first Spring Festival couplets. Until the Song Dynasty, Spring Festival couplets were still called "Fu Tao". There is a saying in Wang Anshi's poem that "thousands of households always exchange new peaches for old ones." In the Song Dynasty, the peach symbols were changed from red boards to paper, which were called "spring stickers" and "Spring Festival couplets".

Generally speaking, it is not allowed to post Spring Festival couplets at home on New Year's Eve, because according to the custom of our country, the married girl is already a family member, and it is not allowed to post Spring Festival couplets at home. Moreover, posting couplets is a man's business and generally does not require girls to do it. In some families, it is easy to cause other unnecessary disputes and misunderstandings. For example, if you stick them at home but not at your husband's house, it will easily lead to family conflicts.
