Also known as Dr. Li and originally named Li Changzhou. He is a respected teacher who survived a childhood tragedy where seven children died in an air-raid shelter. After the incident, his parents changed his name from Changsheng due to a fortune teller's advice and moved away. For twenty-three years, he was haunted by the vengeful spirits of his childhood friends who died because of him. He was a strict materialist before encountering supernatural events. He jokingly joined the Moon Cult during a counseling session, which later led to his rescue.
