In Chinese poetry, a couplet is a pair of lines of poetry with certain rules.
A couplet must adhere to the following rules:
- Both lines must have the same number of Chinese characters.
- The lexical category of each character must be the same as its corresponding character.
- The tone pattern of one line must be the inverse of the other. This generally means if one character is of the level (平) tone, its corresponding character in the other line must be of an oblique (仄) tone.
- The last character of the first line should be of an oblique tone, which forces the last character of the second line to be of a level tone.
- The meaning of the two lines need to be related, with each pair of corresponding characters having related meanings too.
Outside of poems, they are usually seen on the sides of doors leading to people’s homes or as hanging scrolls in an interior. Although often called antithetical couplet, they can better be described as a written form of counterpoint. The two lines have a one-to-one correspondence in their metrical length, and each pair of characters must have certain corresponding properties.
Based on the information on https://en.wikipedia.org/wiki/Antithetical_couplet
it is interesting to listen to the pinyin: duìlián
Note: with some imagination we could phonetically transfer that perhaps into ‘daiin’.
In 1605, the Jesuit missionary Matteo Ricci published Xizi Qiji (《西字奇蹟》; Xīzì Qíjī; Hsi-tzu Ch’i-chi; “Miracle of Western Letters”) in Beijing. This was the first book to use the Roman alphabet to write the Chinese language.
What is also interesting are the rules, for pinyin. For example:
AA: Duplicated characters (AA) are written together: rénrén (人人, everybody), kànkan (看看, to have a look), niánnián (年年, every year)
ABAB: Two characters duplicated (ABAB) are written separated: yánjiū yánjiū (研究研究, to study, to research), xuěbái xuěbái (雪白雪白, white as snow)
AABB: Characters in the AABB schema are written together: láiláiwǎngwǎng (来来往往; 來來往往, come and go), qiānqiānwànwàn (千千万万; 千千萬萬, numerous)
