The next morning, the police arrive at the police station to find Sun lying dead in his room. He has been dead for about a month. The police chief tells him that he is the only one who has committed suicide by jumping from a building. He tells the chief that he can only find out about the man's memory by looking at his clothes and shoes. The chief asks the police captain to bring him to the room of the man who committed suicide. The captain tells the police chief that the man was a student named wangbaogang, who liked leather shoes, suits, and dressing up as a teacher. He took the keys of the building and went to his room to check on his body. He left his shoes in the wet floor of his room all the time.
