This chapter's epigraph comes from a poem by a famous poet named Duan. Duan's poem is about a young girl who faints and is rescued by her parents, who treat her like a daughter. The girl's parents are the ones who brought Duan home and treated him like a son. The little boy who saved Duan is called "Tang zheng" , and Duan asks him who taught him martial arts. The boy tells him that he learned it from a sixth-grader who was also his teacher. The old man, who Duan calls "the old man," tells the boy that he does not know where his master is, but that he is free and unrestrained.
