What is the description and expression of science children's poetry in the language and form of poetry?

There are many ways to express poetry. The traditional way of expression that was first popular in China and has been used to this day is "Fu, Bi and Xing". "Preface to Mao Poetry" says: "Therefore, poetry has six meanings: one is wind, the other is fu, the third is comparison, the fourth is prosperity, the fifth is elegance, and the sixth is ode."

In the meantime, there is a quatrain called "three lights, the sun, the moon and the stars, four elegant poems."

In the six meanings, "style, elegance and praise" refers to the types of poems in the Book of Songs, and "Fu, Bi and Xing" are the expressions in poems.

Fu: It is a way to express things directly. Zhu, a scholar in the Song Dynasty, said in the note of Biography of Poetry: "Fu is telling the truth."

For example, The Book of Songs, Ge Tan and Wild Goose used this technique.

Bi: It is to use metaphors to describe things and express thoughts and feelings. Liu Xie said in Bi Xing: "What is Bi Ye? When you write something to add meaning, you threaten to cut it off. " Zhu said, "If you compare one thing, you can compare it with another." For example, the book of songs such as Cat and Mouse is written in this way.

Xing: It is the way to revitalize things, that is, to borrow something from the beginning to describe things and express thoughts and feelings. In the Tang Dynasty, Confucius said, "Xing, starting from the class, starts from one's own heart. In poetry, all the plants, animals and birds are raised to see what they mean, and they are all happy with words." Zhu pointed out more clearly: "Xing, let's talk about other things first, so as to cause the lyrics to be sung.

These three methods of expression have been handed down all the time, and they are often used comprehensively and complement each other, which has a great influence on poetry creation in past dynasties.
