Zhou Yuanshu was from Suiyang, and served as Secretary-General to Pinglu, residing in the official dwelling at Linzi. One night, when he was about to go to bed, he suddenly heard the sounds of a great many horses and heavy baggage carts. Knocking on his door he sent someone out, who reported: “Li Sikong waits to call on you.” Yuanshu thought through the people he knew, but this was not among them. He therefore concluded: ‘He must be somebody from my home region I do not yet know.’ He then went out to see the guest, invited him to be seated, and asked politely where he had come from. The reply came: “I come to make my home at this very place, and have not yet anywhere to stop, so seek to dwell in this residence.” Yuanshu was shocked, and asked: “Why come here?” He replied: “This is our former home.” Yuanshu said to him: “I came here on an official post, and the house has long been passed down as a government residence. When did the gentleman live here?” The other replied: “I lived here once in the Kaihuang era under the Sui.” (i.e., 581-601 CE) Yuanshu said: “In that case, must not the gentleman surely be a spirit?” He said: “Yes, indeed. The regional officials have permitted me to establish a shrine here, and therefore ask the gentleman simply to move on.” Yuanshu could not agree, and said: “People ought not to mix with spirits. Can it really be that I am about to die, and the gentleman can therefore bully me? Even if that is so, there are no grounds for handing over this residence to the gentleman. Even were I to die, I should still make my case against the gentleman.” He therefore summoned his wife and children, and told them: “I am going to die. Place plenty of paper and brushes in my coffin, as I am going to engage in a disputation with the gentleman Li.” They provided wine to drink, and the pair made several hundred toasts, their speech growing ever more stern. The visitor seemed about to depart, but stayed back, and, after a long time had passed, a servant came and spoke: “A message for the lady from Sikong. Secretary Zhou is emotionless. How can one dispute with such a person? He invites catastrophe.” At this the visitor then said farewell and departed. They showed him to the door, and he then suddenly vanished. Yuanshu remained in good health.
