Spring Festival couplets originated in Fu Tao. "Fu Tao" is a rectangular red wooden board hanging on both sides of the door in the Zhou Dynasty. According to ancient books, in ancient times, people thought that peach wood was a kind of "fairy wood" with the function of exorcising ghosts and evil spirits. At that time, Fu Tao was six inches long and three inches wide, and the names of "Shen Tu" and "Lei Yu" were engraved on the book. On the first day of the first month, every family hangs the new Fu Tao at home, hoping that everything will be fine in the new year. This custom continued until after the Sui and Tang Dynasties. People gradually wrote some auspicious words on peach symbols, and then decorated the couplets to highlight the festive atmosphere of the New Year, gradually forming the embryonic form of Spring Festival couplets. During the Five Dynasties, Meng Changjun, the last emperor of the post-Shu regime, was quite literary. One year during the Spring Festival, he personally wrote the couplets of "Spring Festival in Qing Yu and Spring Festival in Changchun" on the mahogany board, which was the first Spring Festival couplets recorded in the state-owned history books of our country. Wang Anshi, a great scholar and writer in the Northern Song Dynasty, wrote in his poem "Yuan Ri" that "every family always trades new peaches for old ones". It can be seen that until the Song Dynasty, many people still called Spring Festival couplets "Fu Tao". But since then, people have gradually replaced the mahogany board with paper, and the mahogany symbol is also called "Spring Sticker". In the Ming Dynasty, Fu Tao officially changed its name to "Spring Festival couplets". According to Chen Yunzhan's Miscellaneous Notes on Mao Yunlou in the Ming Dynasty, from Zhu Yuanzhang, the Ming Emperor, it was explicitly required to stick couplets during the Spring Festival. One year before New Year's Eve, Zhu Yuanzhang suddenly issued a decree that all the people in the capital, whether citizens or citizens, should put up a pair of Spring Festival couplets at the door of every household, and he would check it himself anonymously. Sure enough, Zhu Yuanzhang not only personally went out of the city to check, watch and share, but also personally wrote a pair of interesting couplets. He passed by a family and saw that there was no Spring Festival couplets on the door, so he asked the reason. He knew it was a castrated pig, and he didn't know what to write. After a little thinking, he wrote the Spring Festival couplets "Split the road of life and death with both hands and cut off the root of right and wrong with one knife", and everyone present felt that the couplets were appropriate and humorous. Under the advocacy and practice of Zhu Yuanzhang, the founding father of the Ming Dynasty, Spring Festival couplets gained unprecedented popularity in the Ming Dynasty. Since then, Spring Festival couplets have become an important cultural custom for all China people to celebrate the Spring Festival, and have been passed down to this day.
