Pay attention to the following points when writing couplets:
First, the words are equal. Couplets can have one word or more words. How many words are the first part, how many words must be the second part. You can't go up more and fall less, or go up less and fall more.
Second, the parts of speech are the same. Verb to verb, adjective to adjective, quantifier to quantifier, adverb to adverb and relative words must be in relative positions.
Third, the level is relative. Couplets are a style separated from poetry. According to two words and one syllable, the upper part of the two words is flat, and the lower part must be flat, so it has a sense of rhythm. You can't even talk to each other. You can't even talk to each other. Especially the last three words, there can be no three-level crown and three-level tail.
