In this chapter, Guizhou tells his sister about the argument he had with her. He tells her that she was still a broken-hearted girl before she got married, and that she should not have gotten married so young. He also tells her about his brother, who is a year older than Guizhou, and how they are not alike. Guizhou asks her to share some of her learning experiences. She tells him that she is the one who tutors his homework, although it is a pity that Guizhou's certificate for the "best student award" was lost. She also tells him about the hero cards she and her brother collected when they were younger. They used to collect cards for each story they told, and each card was given to the person who told the story the best. When Guizhou was older, he used to get the best card for the best story, and Guizhou would get the card for every story he told. He was very angry, but he did not have enough money to buy the card, so he bought his brother's favorite mechanical keyboard.
