Thirty-six lines of poetry, * * * is divided into nine groups, a group of four sentences, a group of three rhymes, and the other group must use another rhyme, like nine quatrains. This is its neat side. Its intricacy is reflected in the level change of nine rhymes. At the beginning, the first and third groups use flat rhymes, the second and fourth groups use flat rhymes, and then all the 5678 groups use flat rhymes, and finally end with rhymes, interspersed at will, and the tone is neat and not rigid. Syntactically, parallelism, antithesis and flowing pairs are widely used, and the cohesion and integration are wonderful, and the article is full of charm.
