In class four, a boy named Xiao tells his teacher that he wants to go to a private school to play some games. The teacher tells him that the school will not be open during the national holidays. The boy tells the teacher that a girl and a boy are playing the same game, and that the boy has lost to the girl before. He tells the boy to go compete with the girl if he thinks he is good enough. The girl tells him to sit down and punch, but the boy refuses to do so, saying that he will beat the girl one day.
