There are a few things to consider when writing a dialogue between characters in a novel: 1. Confirm the background and context of the conversation. Character conversations should take place in specific situations such as a battle, a decision, a trip, and so on. In this situation, the characters should have their own background and purpose so that the reader can better understand their dialogue. 2. Give the character a personality. Every character should have their own personality and characteristics, such as intelligence, stupidity, courage, selfishness, and so on. These characteristics should be expressed through the language of dialogue so that readers can better understand the characters. 3. Use the tone and expression of the conversation. The tone of the conversation should be in line with the situation and the character's personality, such as relaxed, serious, humorous, etc. The expressions in the dialogue should also be reflected, such as joy, sadness, anger, etc., so that the reader can better feel the emotions of the characters. Pay attention to the structure and rhythm of the conversation. The structure of the dialogue should conform to the plot and situation of the story, such as simple sentences, complex sentences, long sentences, short sentences, etc. The rhythm of the conversation should also be reflected, such as fast, slow, tense, relaxed, etc., so that the reader can better feel the rhythm and emotion of the conversation. 5. Use the hints and metaphor of the conversation. In the dialogue, hints and metaphor can be used appropriately to let the readers better understand the meaning and extension of the story. For example, through the dialogue between the characters, it hinted at the relationship between the characters, the development of the story, and so on. I hope these suggestions will be helpful. I wish you good results in your writing!
