The so-called "image" is an objective image used to pin the author's subjective feelings; The so-called artistic conception is that the author unifies his subjective feelings with the description of objective scenery, and shows meaningful images in this unity. For example, Lu You's "Scattered mud grinds into dust, only the fragrance remains the same" describes the image of plum blossom that is not afraid of setbacks, dares to be the first in the world, and is noble. Artistic conception is the unity of a group of images, such as: "the old vine is faint, the small bridge is flowing, the old road is thin, and the heartbroken person is in the end of the world." It can not only carry out concrete images, but also read the harmonious artistic conception more easily.
