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 words "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 Shi Sui Ji" said: "Spring Festival couplets, that is, Fu Tao."
