Jin Shicheng was a native of Changshan who had never behaved with propriety. Suddenly he became a wandering mendicant priest, behaving as if mad, finding pleasure in eating filth as though it were a delicacy. Whenever dogs and goats left their droppings before him, he would stoop and devour them. He styled himself a Buddha. The credulous common folk and women, marveling at his doings, became his disciples by the tens of thousands. When Jin ordered them to eat excrement, none dared disobey. He raised halls and pavilions, spending money without limit, which people gladly contributed. Magistrate Nan of the county, disgusted by his monstrous behavior, seized and flogged him, making him repair the Confucian temple. His disciples vied in announcing, "The Buddha is in trouble!" and vied in raising funds to ransom him. The temple was finished within a month, and his gathering of money was swifter than the harsh summons of a cruel tax-collector.
The Historian of the Strange remarks: "I have heard of this Taoist Jin, whom people called by his name, saying he was 'a Buddha for the present age.' To go so far as to eat filth is the very extreme. Flogging him could not add to his shame, and punishing him served only a good end—how excellent was Magistrate Nan's handling of the law! Yet for the Confucian school to fall into ruin and require a monstrous priest to repair it is also a disgrace to the scholar-officials."
