Whether you use the first or third person when writing a novel depends on the writing style and the plot. The first person was usually used to describe a character's personal experience or to describe the character's emotions and thoughts directly. This would allow the reader to get closer to the story and create a stronger sense of immersion. For example," I " could be a protagonist, describing his life experiences, emotions, and thoughts. The reader could understand the story from the perspective of " me." Third-person narrations are usually used to describe events and characters 'actions, allowing the reader to view the story from a bystander's point of view more objectively and calmly. For example,"he" or "she" could be a protagonist, but the reader would not directly feel the emotions and thoughts of the protagonist. Choosing to use the first or third person depended on the story and writing style.
