Most editions tie this lot to Ma Chao chasing Cao Cao, as told in the novel Romance of the Three Kingdoms, while one names it after its own image, treasure found in a dream. In the novel, Cao Cao has killed Ma Chao's father, and Ma Chao comes east with his cavalry for revenge. At Tong Pass he routs Cao's army and rides Cao himself down. Hearing his pursuers shout for the man in the red robe, Cao throws off the robe; hearing them shout for the long beard, he hacks it short. Cao Hong arrives to rescue him at the last moment, and Ma Chao is left with nothing. The prize was within arm's reach and vanished, which is exactly how a dream of treasure feels on waking. That is the lesson of a lower lot: what seemed already won was never really held.
