1.

2. Couplets, also known as couplets, door pairs, spring stickers, spring couplets, antithetical couplets, peach symbols, couplets (named after the couplets that were often hung in the halls and houses in ancient times), etc., are a type of couplets. This kind of duality literature is said to have originated from Taofu. Another source is spring couplets. The ancients often posted the word "Yichun" on the first day of spring. Later, they gradually developed into spring couplets, which express the Chinese working people's good wishes to ward off evil spirits, eliminate disasters, and welcome good fortune. Couplets are dual sentences written on paper, cloth or carved on bamboo, wood, or pillars.

3. Parallel prose and verse are the two direct sources of couplets. In the process of its own development, couplets also absorbed the characteristics of ancient poetry, prose, lyrics and music. Therefore, in addition to verse and parallel prose, the sentence patterns used in couplets also include ancient poetry, prose, and imitation of lyrics and music. Different sentence patterns have different applicable rhythms and different leniency and severity.

4. As a custom, couplets are an important part of Han traditional culture. In 2005, the State Council of China listed the custom of couplets in the first batch of national intangible cultural heritage lists. The custom of couplets has been passed down and spread among the Chinese and even in regions around the world where Chinese is spoken and among ethnic groups that have cultural origins with Chinese characters. It is of great value to the promotion of Chinese national culture.

5. It is generally believed that couplets are the most unique literary form in China. Where does its uniqueness lie? Mainly in structure and language. Couplets can be called "dual structure" style. A standard couplet always consists of two parts that oppose each other. The former part is called the "upper couplet", also called "chuju", "opponent" and "duigong"; the latter part is called the "lower couplet". Also called "couples", "duiwei" and "duimu". Two parts come in pairs.

6. Only the first couplet or only the second couplet can only be regarded as half a couplet. Of course, many couplets, especially those written and hung, have horizontal scrolls in addition to the upper and lower couplets. Horizontal comment is an organic part of this kind of couplet. It is often a summary, finishing touch, or consistent with the couplet. It is usually four characters, but there are also two, three, and five characters. One word or seven words.
