It is not the seven laws that require antithesis, but the laws and poems all require antithesis. There are five words and seven words in regular poems, and there is a rare six-word regular poem. The antithesis not only embodies the beauty of neatness, but also forms the cadence of rhyme, that is, the beauty of melody. Generally speaking, except for the first pair and the second pair, all other couplets require antithesis. But in reality, the author often does not fully meet this requirement. Generally speaking, just don't use words to hurt!
