When the teacher arrives, the gang is ready to go to class, but the headmaster refuses to let them go. He tells the students that he needs to teach them a lesson, or else they'll keep coming back. The gang leader, wangxiaoxiu, is happy that the teacher arrived on time, because otherwise, he'd have been kicked in the guts. He's also excited because he's the leader of the gang, and he thinks he can beat the teacher with his fists. He asks the teacher if he thinks a strong fist makes you a good fighter, and the teacher says that he doesn't think so. .
