Dengzhou Miao Gongyan, when his father was young, once entertained a few friends who had not seen each other for a long time at home. Everyone was very happy and drank until late at night, and they were all seven or eight points drunk. At this time, a person named Liu Sheng took a wine glass and stood up to toast everyone, but fell headfirst to the ground. Everyone only said they were drunk and came to his aid. Unexpectedly, he suddenly stood up, his expression changed, and he asked everyone, "What is the land here?" Everyone saw that his expression and words were different, unlike usual, and they suspected that he was possessed by a ghost. They were all very afraid, and they all had no masters. Master Miao had served in the army and had some courage. Seeing this, he said to him, this is a village somewhere. I saw Liu Sheng after thinking for a moment, as if he wasn't going far.

Miao Gong heard the words, Where is the immortal going, and why is he possessed in the body of a mortal today? I only heard Liu Sheng say, I have something to ask for, but I don't know if you can trust me? Miao Gong replied, if it wasn't for hurtful and illegal things, how could I not do it? Liu Sheng was satisfied now, so he said, I was caught in a trap a few days ago and arrested. At this time, I am locked in a courtyard in a certain village. If I can help you, I will not forget your kindness. The place Miao Gong heard him say was not very far, but I didn't know the family. Although that was the case, I still agreed. When I arrived at the house overnight, it was already very deep. The owner's family was probably sleeping soundly. Miao Gong saw that the courtyard was just a bamboo fence, only waist-high. After entering, he saw a wooden box in the corner, and a weasel was locked in the wooden box, looking at him as if waiting for his arrival.

When he got home, his friend Liu Sheng was already awake, and everyone asked him what happened when he was unconscious. However, he could no longer remember anything. Since then, the weasel would often appear in Duke Miao's house, sometimes catching mice in the house, and sometimes reporting pheasants and hares.

One night, Miao Gong dreamed that a man in yellow arrived, and he fell to the ground and called Miao Gong his benefactor, and said, "The benefactor is a good man from the third generation. In this life, he will have a wealthy family, peace and wealth, and pain and disaster have nothing to do with you and your family. But how can you not repay your life-saving grace? I have to do small things for you to watch the house and protect the house, and hunt for some mountain goods to repay you. I hope you don't dislike the slightest gift. Miao Gong often said to people in the future that although this weasel didn't have a big favor for me, his heart to repay his kindness was more than that of ordinary people. The spirituality of animals is like that of humans.
