The similarities between autobiography and biography lie in that both of them are about the life of characters. The difference is that autobiography is written about the author himself, while biography is written about others. That is to say, in autobiography and biography, there are fundamental differences in the relationship between the writing subject and the historical subject, which brings about other differences between autobiography and biography. In biography, the author is behind the text. He is hidden, or, as EdelEdel, Leon says, a “figure under the carpet.” In autobiography, however, the author overtly assumes the central position of the text.
