The ancient writing habit is to write couplets vertically from the right, with the right as the top, that is, the upper couplet is on the right and the lower couplet is on the left. Couplets, also known as antithesis, antithesis, spring stickers, Spring Festival couplets, couplets, Taofu and couplets (named after the pillars hanging in halls and houses in ancient times), are a kind of dual literature, which originated from Taofu. Another source is the spring release. The ancients posted the word "Yichun" more and more at the beginning of spring, and then it gradually developed into Spring Festival couplets, expressing the good wishes of the working people in China to ward off evil spirits and avoid disasters and welcome good luck. Couplets are antithetical sentences written on paper, cloth or engraved on bamboo, wood and columns. It is a unique art form of Chinese, concise and profound, neat and even, with the same number of words and the same structure.
