Whether you use the first or third person when writing a novel depends on the plot and theme of the novel. First-person writing is often referred to as "autobiographical" writing. The reader can participate more deeply in it and feel the author's emotions and experiences. This writing style was suitable for personal stories or novels with more detailed and complicated plots. For example," Dream of the Red Chamber " was a novel that was mainly written in the first person. The readers could have a deeper understanding of the relationship between Jia Baoyu and Lin Daiyu. Third-person writing is often referred to as "narrative" writing. The reader cannot participate directly in it but can understand the story through the author's perspective. This style of writing was suitable for novels that told complex plots and characters, as well as novels that needed to show the interactions and relationships between different characters. For example, Romance of the Three Kingdoms was a novel that was mainly written in the third person. The readers could understand the history and characters of the Three Kingdoms more objectively. The choice of first or third person depended on the plot and theme of the novel. If you need to show your personal feelings and experiences or need to tell a complex plot and character relationships, it might be better to write in the first person. If you need to tell an objective story or show the interactions and relationships between different characters, it might be better to write in the third person.
