The first person, second person, and third person could be interchanged in the novel, depending on the style of the novel and the author's wishes. First-person narration usually allows the reader to understand the story from the protagonist's point of view. It can enhance the reader's sense of immersion and allow the reader to feel the plot and emotions of the characters more personally. Therefore, the author could flexibly use the first person to shape the characters and promote the development of the plot according to his own writing style and plot needs. Second person narration allows the reader to participate in the story as the author or protagonist, which can increase the narrative power and depth of the novel, allowing the reader to better understand and feel the emotions and psychological state of the characters. Therefore, the author could also use the second person to enhance the emotional atmosphere of the novel. Third-person narration was to tell the story as a bystander, which could allow the readers to understand the plot and characters more objectively, and at the same time, it could also increase the narrative effect and rhythm of the novel. Therefore, the author could use the third person to show the perspective and point of view of different characters to enhance the narrative and readers of the novel. Using the first person, second person, and third person in a novel has different effects and advantages. The author can flexibly use different people to shape the characters and promote the development of the plot according to his own writing style and plot needs.
