Perhaps the most abstract form of expression in literature is abstract description. An abstract description was to express the author's feelings and thoughts by describing abstract concepts such as concepts, emotions, and thoughts instead of directly describing specific images or scenes. This form of expression helps the author to establish emotional resonance and understanding in the reader's heart, so it is considered one of the most abstract forms of expression in literature. For example, Calvino, the master of modern literature, had many abstract descriptions in his works, such as "a lonely forest","a sunny morning","a dark night", etc. These descriptions did not seem to directly involve specific images or scenes, but they actually expressed the author's emotions and thoughts.
