After graduating from high school, the narrator writes a letter to his teacher. He apologizes for the trouble he's having with his classmates, but he doesn't want to apologize to the teacher, because he thinks the teacher is too busy to be bothered. He tells the teacher that he'll be his teacher, not a teacher anymore. The teacher agrees, and the narrator tells him that his name is Shen sheng, and he is a student of the teacher's. The narrator says that the editor of his story has told him that it's not suitable for publication now, but the teacher assures him that there's no conflict between his writing style and his business writing style. He also tells the narrator that he should be careful not to tell anyone about his writing, because some of it is "rubbish" . He says that he wants to return to his studies now, and that he hasn't seen the teacher talking so seriously in a long time.
