Why can Bao Zheng find out the murderer of headless corpse through divination?

Zhouyi, divination, divination, etc. Today, it is regarded as a feudal superstition by many people, but few people will say that if you read the Book of Changes thoroughly, you will become a fortuneteller. This fairy doesn't mean that she can live forever, but that she can see through the way of nature and the laws of all things and stop being confused about the world. As for predicting life, future, karma, etc. That is even more obvious. There are still these people who call themselves fortune tellers in many streets.

But in ancient times, divination had another function, which was to solve crimes.

In the Northern and Southern Dynasties, the former Qin emperor Fu Jian had a younger brother named Fu Rong, who was good at divination and tried to solve a bizarre case of killing his wife. After Chen Ziang was imprisoned in the Tang Dynasty, he also calculated himself and died in prison. Bao Gong An, a case-solving novel in Ming Dynasty, also recorded the story of Bao Zheng using divination to solve the case.

The general process of the case is as follows:

In Yuanzhou, under the jurisdiction of Tokyo (Kaifeng, the capital of the Northern Song Dynasty), there are two brothers, one is Zhang Chi and the other is Zhang Han. The two brothers live together. Married Zhou and gave birth to a child at the age of 1. Then one day, Zhou's mother was seriously ill and sent someone home to call her daughter back to visit.

Before Zhou He and their children arrived at their parents' home, their mother had recovered, but they stayed at their parents' home for a month. Later, Zhang Chi was invited to a friend's house and told his brother Zhang Han to take his wife and children home. Zhang Han went on his way after receiving his sister-in-law and nephew. It was very hot on the road in summer, and his sister-in-law had a hard time holding the child. Zhang Han suggested that he take his nephew home first and let his sister-in-law wait in the shade of the road for a while. He hired a sedan chair himself.

As a result, when Zhang Han came back again, her sister-in-law disappeared, and she didn't go to her parents' house to ask. Later, my sister-in-law's body was found in a remote place on the mountain, and her head was gone. Uncle Zhou sued for raping his sister-in-law, and the county magistrate beat him. Zhang Han pleaded guilty to imprisonment, but was executed in the autumn.

Six months later, Bao Zheng traveled around the country. It was strange to see this case, but he didn't have any evidence himself, so he asked someone to find a fortune teller. Bao Zheng asked the man to calculate the hexagrams in "Escape from Tianshan Mountain", and the hexagrams are: If you encounter hexagrams, you can ask. Yu's family went to the east, and the sugar mouth was full of rice.

Bao Zheng just wanted to think. He asked his neighbor Xiaomou to take two officers to Jiankang (now Nanjing) to inquire about the Zhang family.

This inquiry really saw his wife Zhou, and Xiaomou quickly let your official catch two people who kidnapped Zhou. It turned out that Zhou rested on the mountain that day. When they saw her alone, they forced her to take off her clothes and write, let a woman put it on, then killed the woman and took Zhou to beg along the way.

They didn't understand, and asked Lord Bao how he knew Zhou was in health. Promise smiled and said: Yu's family went east, and there was no Yu, so the bottom of Yu's family's departure was the word "sword"; "Rice comes out of chaff" means taking rice out of chaff, which is naturally the word Kang, and together it is Jiankang (now Nanjing). The body is headless, so it is hard to tell if it is Zhou. In addition, there are many merchants in Jiankang, so I suspect that Zhou has been abducted.
