Description of one's own life experiences: autobiographies are usually narrated from the perspective of the protagonist. Therefore, it is necessary to describe the protagonist's own life experiences, including his family, education, work, love, marriage, illness, rehabilitation, etc. 4. Prominent personal feelings and experiences: autobiographical novels usually focus on the protagonist's personal experiences, so it is necessary to highlight personal feelings and experiences so that readers can better understand the protagonist's inner world.
