In a scene from “Robber South” (2001), which tells the story of a young man in the city making a living as a fruit seller while dreaming of becoming a businessman, the protagonist watches as a subway train pulls into a station, and in an instant the focus of his attention switches seamlessly to a deep blue sky. Compass in hand, he walks from house to house, tracing each door and wall with his fingers, a metaphor for his search for his own place in the city.
