The narrator explains that the story does not intend to describe real events or characters. It is merely a coincidental coincidence. He says that he is satisfied with his profession within the past 20 years. The professor of language, jiang, is talking about a student named momo Xue, who has just written an excellent essay. jiang says that the student's name is written on the essay, and shuyuan says that his name was also written on it. The narrator says that if he took the original essay and copied it, the original would be on his own hard drive, not on momo's. If he took out the student, everything would be completely exposed. He then shows the professor and his students the history of his hard drive and says that there is no essay there. He claims that the browsing history is all about luxury goods.
