When Wang Changling was the county magistrate of Tongjiang, law enforcement was strict, he was unselfish, and he was a good and honest official. Once, a case occurred in the area under his jurisdiction. A passing merchant who was drunk beat people to serious injuries and was caught on the spot. Witnesses and physical evidence are very clear. Although such a case does not lead to a capital crime, the consequences are also very serious. The criminal will be stabbed in a distant prison camp to be punished. It is often impossible to predict the future of life and death. The night before the sentencing. Wang Changling dreamed of a visit from an old friend, who he had not heard from for a long time. After the two exchanged pleasantries, the man said to Wang Changling, I know you are an honest official, but the criminal in the case you are currently handling is my unworthy son. How can I dream of standing by and watching in such a situation? If you can remember the friendship between us, please deal with it and avoid severe punishment, I can die without regret.

Wang Changling told him in his dream that this case was right and wrong, and all parties have admitted the cause and effect, and the law on which the punishment was based is also very strict. I am even afraid that I am powerless, and I hope to get your understanding. The man was very dissatisfied after hearing this, and said angrily, "When you went to the exam, you lent me ten taels of silver and did not return it, and now you should repay my favor. Wang Changling replied, "I have not forgotten, and I also remember your kindness. When I was able to return it, I did not hear from you, which was not my original intention. The man became even more angry after hearing this, and scolded him. Now I am also a ghost. If you insist on going your own way and do not want your old feelings, don't blame me for turning your face and being ruthless. After saying that, I left angrily. When Wang Changling woke up suddenly, he realized it was just a dream.

The next day, Wang Changling was not affected by the dream, and insisted on judging the case according to the law, sending the criminal to a vicious place. Before leaving, he collected twenty taels of silver and gave it to the prisoner, explaining that he would not be embarrassed along the way. Only then did he feel relieved. A year later, Wang Changling will report to the capital. He brought two or three entourages. One night, he walked to a river. At this time, he saw a fierce white-clothed ghost with a shaggy head and screams. He carried a big knife and floated away. He shouted, "Ruthless and unrighteous people, take your life! Wang Changling was shocked when he saw it. The person who came was his old friend, the father of the criminal, and the person who supported his dreams.

At this time, the attendants all shouted and fled, and Wang Changling also ran forward. The ghost was chasing after him wielding a big knife, and the ghost did not disperse. Looks like it was about to catch up. At this time, a team of ceremonial guards came on the road, and it looked like the king was on patrol. Wang Changling could take care of a lot at this time, and when he saw this, he rushed to the front of the driver and shouted for help. I saw the ghost hiding by the side, not daring to show up. Wang's escort took Wang Changling down long ago, but someone sent an order to the guard, and Great Emperor Dongyue stopped the driver to ask questions. Wang Changling said in shock after hearing that it was the Great Emperor Yin Si who had arrived. Then he went to the emperor in fear and knelt down to reply.

The Great Emperor of Dongyue asked about his place of origin, what happened? Wang Changling answered truthfully one by one. After hearing this, the Great Emperor of Dongyue ordered the guards to take the ghost. The guards arrested the evil ghost in front of them in an instant. The emperor said, how can human love interfere with the law. How do you care about the affairs of the young world for ghosts and disturb the laws of the yin and yang world? Today I will send you to the hard labor room, and when you have suffered criminal law, we will discuss reincarnation. As soon as the words fell, a guard drove the wind to take the evil ghost. The Great Emperor of Dongyue encouraged Wang Changling a few more words, praising him for his strict law enforcement and selflessness. Only then did he lead the guards to leave. This pair of ghosts, father and son, one who despised the law and the other who regarded the law as a child's play, finally got the end they deserved!
