The Book of Songs is mainly composed of four words and miscellaneous words. Structurally, the form of repeated chapters and sentences is often adopted to enhance the lyrical effect. Only a few words are changed in each chapter, but it can receive tortuous and changeable artistic effects. In language, we often use disyllabic rhymes, reduplications and conjunctions to describe things and imitate sounds, which is poor. "Less is always more, and the situation is very clear." In addition, some rhymes in The Book of Songs, some rhymes in every other sentence, some rhymes at the end, and some rhymes in the middle. The rhyming rules of modern poetry are almost all in the Book of Songs.
