The origin of couplets:

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. It is a antithetical sentence 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.

Couplets are the treasures of China traditional culture, and the earliest recorded couplets appeared in the Three Kingdoms period. During the Hongwu period of the Ming Dynasty (1368- 1399), an extra-large iron cross was unearthed in Luling, Jiangxi Province (now Ji 'an City, Jiangxi Province), on which the year number of Sun Quan Chiwu in the Three Kingdoms period (238-250) was cast.

On the iron cross, there is also a beautifully made couplet cloud: "The four seas celebrate An Lan, and the iron column leaves a cross; All the people are pregnant with Ozawa, and the golden stove is fragrant for thousands of years. " Its form and content are related to early Christians in China. Spring Festival couplets are called Spring Festival couplets, funeral couplets are called elegiac couplets, and wedding couplets are called violet couplets.

Couplets are a national style written by using the characteristics of Chinese characters, and generally do not need to rhyme (only the antitheses in the rhyme need to rhyme).
