Couplet skills 1. As we all know, if the number of words in the upper part is the same and the upper part is a word, then the lower part must also be a word.
2. The parts of speech of couplets must be the same, nouns belong to nouns and verbs belong to verbs. For example, the first two words of the upper couplet are verbs, and the first two words of the lower couplet are verbs.
3. The color of the upper and lower couplets should be flat. The end of the first part is silent, the second part is closed, and the end is dull. The rhythm of couplets should also be relative. But one or three words are not necessarily relative, and two or four or six words should be strictly relative.
