Provisions for writing couplets:
When the ends of two couplets are both flat tones with one sound and two sounds, which couplet is big because the antecedent is the couplet; The content of one couplet is small, and the next couplet is for the consequences. Of the two couplets, Ji Xing generously held high the contents of Fu Men Kai, which belongs to the principle and should be the first couplet; The content of peace and auspiciousness in the four seasons is very small, which belongs to the result of good luck and should be the bottom line.
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.
