To solve the problem of appreciating ancient poems, or to understand China's ancient poems, we must go deep into the artistic conception through the images of the works. Our nation's aesthetic habits advocate euphemism and implicature, and we like to pin our emotions on objects. 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.
