Couplets are a unique form of literature and art, which began in the Five Dynasties and flourished in the Ming and Qing Dynasties, with a history of more than 1000 years. As early as before the Qin and Han Dynasties, there was a custom of hanging peach characters in the New Year, that is, writing the names of the legendary shentu and Lei Yu on two mahogany boards and hanging them on the left and right doors to exorcise ghosts and eliminate evil spirits. This custom lasted for more than 1000 years. It was not until the Five Dynasties that people began to paste couplets on mahogany boards. According to the history of the Song Dynasty and the records of Shu, Meng Chang, the king of Shu after the Five Dynasties, awarded a bachelor's degree every year. This is the earliest Spring Festival couplets in China.
