Tang Taizong (r. 626-49 CE) was campaigning in Liao and when he reached Dingzhou there was a spirit by the roadside, dressed in white robes and standing tall atop a tomb, its spirited demeanour especially distinctive. When Taizong sent people to question it, it replied: “Our long-ago defeated the lord’s long-ago; the lord’s present defeats our present. Glory and splendour differ in each age; what use is the bitterness of chasing and seeking them?” Its speech being complete, it vanished. On further questioning, the tomb turned out to be that of Murong Chui.
