The chapter opens with a discussion of the importance of circulation, or the flow of energy, throughout the body. It is said that if a person loses all of his or her qi , it will cause nausea, dizziness, and even death. The discussion is interrupted by the appearance of a man crossing the road. The man asks if he can find his father's name, but the man does not have a photo of him. When the man tells him that he has found his father, the man is surprised to learn that he is a student at his school. He asks if the man could be a teacher, and the man says that he could not find his name. He tells the man that he will let him know if he is able to find the father. The two men discuss the book that the man was talking about, and when the man asks him if he could get a band of aid from his drawer, he says that it is the book of the man's ancestor, the xiao . The men discuss how the heirs to the ancient bloodlines of warriors have come to live in the modern world, struggling against the trials of urban life.
