When writing a novel, is it usually written in the first or third person?

When writing a novel, it is usually written in the first or third person. First-person writing is usually used to tell personal experiences or stories so that readers can directly participate in the story, such as Journey to the West, Water Margins and other traditional martial arts novels. This kind of writing style could allow the reader to feel the development of the plot more realistically and enhance the reader's sense of immersion. Third-person writing was usually used to tell the stories of others or to tell the characters and events in a fictional world, such as the Harry Potter series, Dream of the Red Chamber, and other modern novels. This way of writing allowed the readers to understand the plot and characters more objectively and better explore the fictional world of the novel. The specific writing style chosen depends on factors such as the genre of the novel, the theme, and the audience.
