The main reason for using "Dao" instead of "Shuo" in the creation of novels was to enhance the artistic conception and expressiveness of the language. The word "Dao" had a profound meaning and extension. It could represent a kind of idea, a kind of thought, a kind of realm, and even a kind of feeling. By using the word " Dao ", the author could express the philosophy and values that the character had realized in his heart, allowing the readers to better understand the thoughts and emotions of the character. " Speaking " seemed a little monotonous and superficial, unable to express the artistic conception contained in " Dao." In a novel, the language of a character is not only used to express thoughts, but also to express the character's personality, emotions, and situation. Using the word "Dao" could make the character's language have more meaning and depth, and better show the character's inner world. In summary, using "Dao" instead of "Shuo" can enhance the expressiveness and artistic conception of the language, better express the thoughts and emotions of the characters, and thus better shape the characters in the novel.
