Metaphor illustrates a truth through one thing. On the surface, this writing seems to be dominated by things, but in fact, the purpose of things is to explain some truth.
Lyricism by borrowing things refers to the writing method of describing objective things to express one's thoughts and feelings. The main point of this method is to describe things closely related to changes in personnel, honor and disgrace, life and death. Every grass, tree, brick and stone is filled with the joys and sorrows of the characters everywhere. Although it is only a description of things, every word is full of real and moving emotions.
