It depicts beautiful images and expresses good wishes with neatly contrasting, concise and exquisite words. When people paste New Year red (Spring couplets, blessing characters, window grilles, etc.) on the door of their homes, it means celebrating the Spring Festival. Officially kicked off. Every Spring Festival, no matter in urban or rural areas, every household will choose beautiful red Spring Festival couplets and paste them on the door to bid farewell to the old and welcome the new, adding to the festive atmosphere. Another source of Spring Festival couplets is spring stickers. The ancients often posted the word "Yichun" on the first day of spring, and later gradually developed into Spring Festival couplets. It is said that this custom began in the Song Dynasty and became popular in the Ming Dynasty.
