Hardly had the scholar got home when his wife was killed. How was the murderer found?

If any dynasty in history is the worst, it must be the Jin Dynasty, especially the Western Jin Dynasty. The image of national subjugation appeared in the second emperor of the Western Jin Dynasty, followed by the rebellion of eight kings, which eventually led to the rebellion of five kings. A few years after reunification, the Central Plains was once again in turmoil, and the Hu people went south to establish political power. Among them, a group of barbarians established the pre-Qin Dynasty, and the third emperor, Fu Jian, was afraid in the battle of Feishui.

Fu Jian has a younger brother named Fu Rong, who is very capable, especially in solving crimes. Fu Rong encountered such a situation when he was a school policeman in Beijing.

A scholar named Dong Feng went home after studying abroad for three years. As a result, his wife was killed as soon as he got home. His wife and brother suspected Dong Feng was the murderer and sent him to the government. Dong Feng was forced to admit that he had killed his wife.

Fu Rong looked at the case and felt suspicious, so he interrogated himself. However, the case has passed for a long time, and there is no witness or material evidence, so Rong Rong changed his way.

He asked Dong Feng if he had encountered anything strange when he went home, and if he had gone to divination.

Dong Feng replied that he was just about to go home and had a strange dream. In his dream, he rode through the south, then came back from the north, and finally the horse crossed the south again. This time, Du Nan's horse stayed in the water, but he didn't move. He looked down and saw two suns in the water. One was on the horse's left, white and wet, and the other was on the horse's right, dark and dry. He was afraid and ran to the master to interpret his dream.

The dream interpreter told him that you might go to jail, and you should "stay away from three pillows and avoid taking three baths" when you go home.

When I got home, my wife really let him take a bath and put a pillow for him. Dong Feng remembered what the dreamer said, but he didn't take a shower or put a pillow. When his wife saw that he didn't do it, she took a bath pillow and slept, but she didn't know that her wife died like this.

According to Dong Feng's answer, Fu Rong directly said that the case was solved, and even the murderer's name was known. What's going on here? The following passage is ridiculous, so I'll post it directly:

The ridge is water, the horse is Li, and those who dream of riding south and spinning north and south all follow Li from the ridge. Three hexagrams change at the same time, becoming "reason". "Li" is a woman and "Kan" is a man. Two days, the image of two husbands. Naoto Kan is a law enforcement official. When an official scolded her husband, a woman bled to death. "Look" has two yin and one yang, "Reason" has two yang and one yin, and there are inheritance and translocation. ..... The horse left and wet, wet, water, left water and right horse, Feng Zi also. Two days, Chang Zi also. Feng Chang killed it. -"The Book of Jin"? Biography of fu Rong

Roughly means horse, water, etc. There are specific correspondences in the Eight Diagrams of Zhouyi, but the left side of the horse is a wet day, and the wet represents water, so the left water and the right horse become "wind"; Two days' ears are "Chang", so the murderer's name is "Feng Chang". Why two days can't be "luck" or "luck" is because the word "Li" in the gossip is "two yang and one yin" (the symbol is similar to three, and the middle horizontal is two short horizontal), and one yin represents women and one yang represents men, so it is the word "long".

Finally, when I found this constant peak, it was really the murderer. He had an affair with Dong Feng's wife, and he planned to let Dong Feng take a bath on the pillow to commemorate the incident and then kill him. Unexpectedly, Dong Feng didn't do this, so he killed his wife by mistake.
