At the end of the Yongjia era (307-13 CE), there was a Liu Jiao who lived in Jinling. His elder brother had died young, and his sister-in-law lived as a widow. One night, his sister-in-law and a servant-girl were asleep in the hall when the servant suddenly cried out and hurried to his room. She told him: “On the wall where your sister-in-law sleeps there is a very strange and unwholesome sight.” Liu Jiao quickly picked up a knife and lit the fire. Just as he reached the woman, he saw that there were shapes like human faces on all four walls, their eyes opened wide and their tongues protruding. Some were tigers, some dragons, changing to take on every conceivable shape, and growing as he watched to over a zhang (3.3m) in length. His sister-in-law then died.
