The word 'harmony' in novels usually referred to the coordination, balance, and rationality of the plot, character, and atmosphere of the scene. Harmony in the novel meant that the whole story structure, character relationship, plot development and other aspects presented a relatively balanced state without too much conflict or imbalance. For example, a novel might tell the tragic experience of a character, but the whole story would not seem too pessimistic or desperate due to the coordination of his personality characteristics and behavior patterns. Similarly, a novel may emphasize the evil behavior of a certain character, but the whole story will not seem too absurd or unreasonable due to the harmony of its background, motives, encounters, etc. Harmony in a novel means that the content of the story is coordinated, balanced and reasonable, which can arouse the readers 'resonance and emotional response. At the same time, it also helps to build an attractive and infectious literary world.
