The train arrives at Shanghai South Station, and the narrator tells all the passengers to follow him. He tells them that he has checked the route, and that he doesn't know what the first problem is. He says that the train is already 3pm, and they have bought 6pm return tickets for the trip back to Shanghai. The narrator says that sometimes the results aren't so important as they used to be, and sometimes they don't matter at all. He's not going to repeat his studies, he says, because he's already walking on the same path that others have been walking for eighteen years, and he wants to walk on his own path for the rest of his life.
