It is said that Meng Changjun, the monarch of Shu after the Five Dynasties, was a monarch who liked to be unconventional. On New Year's Eve at the end of 964, he had a whim to let a bachelor named Xin write two sentences on the mahogany board and hang them on the door frame of his living room as peach symbols. These two sentences are "Qing Yu in the New Year, Changchun in the First Festival". Enjoy the legacy of the previous generation in the new year. The second sentence is to the effect that festivals show that spring is always there. Since then, the form and content of Fu Tao have changed, not only by replacing "Shen Tu" and "Lei Yu" with parallel couplets, but also by expanding the connotation of Fu Tao, not only to ward off evil spirits and disasters, but also by adding the content of praying and wishing. This became the earliest Spring Festival couplets in China.
