Xing: to support things to arouse interest, talk about other things first, and then draw out the things, thoughts and feelings that the poet wants to express through association, which is equivalent to the current symbolic rhetoric. Xing means that emotion is in an image, and the image is also an image, so Xing has a realm of self and a realm of selflessness.
It can strengthen and deepen the expression of the ideological content of poetry.
