Yin Ji, a native of the Song Dynasty, said that he could see ghosts since he was a child, and when he was an adult, he tried to talk to ghosts, but every time he could, he was used to it and didn't feel too scared, but he himself didn't know anything about magic. Once he went to visit a friend in Yanzhou, and when he was walking halfway, he saw a yellow-clothed ghost walking on the road with a penny on his back and a post in his hand. Seeing that he didn't look like a ghost, Yin Ji smiled and greeted him and asked him where he was going. The yellow-clothed ghost thought he was not human and told him that he was going to Yanzhou to do something.

The yellow-clothed ghost was a little hesitant and said, I'm afraid it's inconvenient to drink if I have something urgent to do. After a while, he said again, what's wrong with drinking a little? So he sat down. When he was happy, Yin Ji asked, "Can you tell me anything?" The yellow-clothed ghost said that there was a man named Zhu Wen in Yanzhou who was going to teach him a lesson. Zhu Wen was Yan Zhou Ling at that time, the uncle of Yin Ji's friend. When he found out, he asked in surprise, why did he do this? The yellow-clothed ghost said that this person's judgment was unfair, and every time there is a lawsuit, he always favors the poor side, and there is no justice to speak of. Now someone has sued Guangding Mansion, and the manor thinks that he is still clean, so he tacitly allows me to give him the appropriate punishment.

Yin Ji asked again how will he be punished. The ghost in yellow took the penny and said, I will hit him with this, and it will hurt for a month if I hit him, and I am going to hit him three times. What do you think? Yin Ji deliberately excused Zhu Wen and said, since there is no actual rule, can you sell me a thin noodle and beat it? After hearing this, the ghost in yellow deliberately said that these things should be discussed after dinner. Yin Ji understood, so he found an inn by the road and ordered a lot of dishes in the room to entertain him. After eating, the ghost was very happy and said to him, You really have a deep affection for me! What else is there to say? I will do what you told me. After saying that, he got up and bid farewell to Yin Ji and hurried away.

The next day Yin Ji went to Yanzhou, and sure enough, he heard from his friends that Zhu Wen had a back problem last night and it was too painful to get out of bed. Yin Ji went to visit him through his friends and persuaded him. I have heard of your clean name, which makes me admire it very much, but how can the laws of the country make your mileage vary? Truth and money have nothing to do with it. Poverty is reasonable, and it will be full of people for a long time. Do you think this is the truth? Zhu Wen was very unhappy when he heard this, and scolded him for being unreasonable. Yin Ji told him the process of seeing hell in detail, and said that his medicine could not be treated, and he would be fine in a month. Zhu Wen was surprised when he heard that. He didn't really believe it. His nephew said that my friend could go to hell.

A month later, his back was cured without medicine, and Zhu Wen believed it. He summoned Yin Ji and said shamefully, I think everyone is rich and unkind, but I forgot that the law is the yardstick for upholding truth and fairness. How dare I do that in the future! Yin Ji was very happy to hear him say this. Later, Zhu Wen's judgment was indeed fair, and there was no such absurd thing as the defendant and the plaintiff being poorer than anyone else when they went to court.
