Guo Qilin's acting skills in the novel were obviously good, but he attacked his appearance. Perhaps it was because people usually evaluated the appearance of the protagonist in the novel, and this evaluation often affected the image of the protagonist and people's attitude towards the protagonist. Guo Qilin's appearance might become the first impression people had of him and affect their attitude and evaluation of him. Therefore, when people attacked Guo Qilin's appearance, it might be to create a more three-dimensional and interesting character image, and it might also be to promote the development of the story. In novels, the image and appearance of the characters were also one of the important means to shape the character's image. Through people's evaluation of the protagonist's appearance, readers could better understand the protagonist's personality and characteristics, and at the same time, provide more background and storyline for the character setting.
