Xu Qingqing's former best friend and the primary antagonist. She was consumed by jealousy because Gu Yan always liked Xu Qingqing despite them growing up together. She practiced the handwriting of both Xu Qingqing and Gu Yan and switched all their letters since they went to the countryside. She told Xu Qingqing's stepmother about the job introduction letter from Gu Yan, causing her stepsister to take the job. She told the village rascal where Xu Qingqing was going, leading to her rape, and used the five yuan bribe to buy cloth and make a dress so she could happily attend college. She also had someone cause trouble to get Xu Qingqing's medical practice qualification revoked. At the class reunion, she publicly mocked Xu Qingqing, then chased her to the rooftop where she confessed everything and pushed her off the building. Xu Qingqing dragged her down with her, and she died in the fall.
