The Dunhuang shilu reports: When Wang Fan died, a thief opened his tomb and saw Wang Fan playing chupu (a form of boardgame) with someone; he rewarded the robber with wine, and the thief drank it in terror, watching someone lead a bronze horse out of the tomb. That night a divinity arrived at the city gate, announcing that it was the envoy of Wang Fan, that someone had opened his tomb, marking his lips by swallowing dark wine, and that when that person returned at dawn they could verify this and capture him. When the thief entered the city, those on the gate therefore bound and questioned him, and it was just as the divinity had said.
