In novels, the transformation of person refers to the transformation of a character's perspective or tone into another character's perspective or tone to achieve a more vivid and rich description effect. During the transformation, one had to pay attention to the identity, personality, emotions, and other factors of the character to avoid unnecessary misunderstandings or conflicts. At the same time, the person conversion also needed to be carried out according to the needs of the story to achieve the best effect. For example, in the novel Journey to the West, Sun Wukong, as the main character, often used the person "I" to express his feelings and thoughts. In some plots, it was also necessary to change Sun Wukong's perspective to the perspective of other characters. For example, in Dream of the Red Chamber, when Sun Wukong helped Jia Baoyu find the spiritual peach, he used the person "I" to express his views and feelings. In order to achieve a more vivid and rich description effect and ensure the continuity and rationality of the story, the author should carefully consider the identity, personality, emotion and other factors of the characters in the novel.
