What is an image? Image refers to an objective thing that is integrated with the author's subjective feelings, and it permeates the author's aesthetic consciousness and personality interest. Generally speaking, when a poet creates, he will express his feelings with the help of objective things and turn them into images.
For example, the "moon" is an objective thing, but the poet writes it into his own poems to express bright, cold, reunion and scattered emotions. It contains the poet's emotional interest and becomes an image. For another example, willow stands for farewell, grass stands for parting, moon stands for homesickness, wild goose stands for homesickness and wandering, chrysanthemum stands for nobility, seclusion and loneliness, and bamboo stands for integrity and modesty. Dry represents missing, loneliness, sadness, etc. In Shan Jutu on an Autumn Night written by Wang Wei, "After the rain, there is an empty mountain, and it stands in late autumn. There is moonlight in the pine forest, crystal stones in the stream, the sound of bamboo in front of the fishing boat, and the sound of lotus leaves in front of the fishing boat. Why not leave in spring?" We first feel the "empty mountain", "bright moon", "clear spring", "rock" and "bamboo forest.
