Experience the repeated chapters and singing forms in poetry.

Reduplication is widely used in poetry, which is a kind of expression of poetry, that is, the syntax of each chapter is basically the same, only a few corresponding words are changed in the middle, and it is sung repeatedly. The function is to deepen the impression, render the atmosphere, deepen the main body of the poem, enhance the musicality and rhythm of the poem, and let the feelings be expressed heartily. Overlapping means that sentences with the same meaning overlap back and forth. It is often used to express the strong feelings of the characters, giving people the feeling of "a hundred turns and a thousand turns" and "three days around the beam". Making good use of overlapping sentences can make the works have strong artistic charm.
