The antithesis, requirements and words are the same, the structure is equivalent, the level and level are relative, the parts of speech are similar, and the artistic conception is consistent.
Stick to the right, rhyme has the stress of "stick to the right" The so-called "sticky" means that the flat type of the upper and lower parts must be one type: the upper part is type A, and the lower part is type A; If the couplet is B-shaped, it is B-shaped. That is to say, the level of the second word of the last sentence must be the same as that of the second word of the previous sentence, flat and sticky, and the two links must be glued together. The so-called "antithesis" means that the sentence and antithesis of each couplet must be of opposite types: the sentence is type A and the antithesis is type B; If the sentence is B-shaped, the duality is A-shaped. That is to say, in the antithesis, even numbers and even lines are completely opposite. The couplet mentioned here does not necessarily require antithesis, but refers to the so-called first couplet, platoon couplet, neck couplet and tail couplet. As far as the seven laws and five laws are concerned, the first two sentences are the first couplet, the last two sentences are the parallel couplet, and so on. Except for couplets and necklaces, the first couplet and the last couplet are not opposed. There are only four quatrains, so the first two are couplets and the last two are couplets. All associations need to stick to it, which is what we often say.
