On August 1, 2011, in Wuyun Town, Jinyun County, Zhejiang Province, this peaceful town fell asleep at night with cicadas singing in midsummer.
At this moment, a woman's harsh scream pierced the entire night sky, and then a man's terrified voice shouted: "Kill, help."
Villagers living nearby heard the sound and woke up from their sleep to find that it came from the family surnamed Cao.
Villagers living nearby heard the sound and woke up from their sleep to find that it came from the family surnamed Cao.
When the villagers opened the door, they saw a bloodied man running past the door, looking like the grandson of the Cao family.
Behind him was a man with a knife who quickly chased after him, and the villagers recognized the man as Zheng Yongjun, a neighbor of the family surnamed Cao.
Why did the neighbor Zheng Yongjun kill the family surnamed Cao? What is the relationship between the Zheng family and the Cao family? Let's take a look at the life of the Zheng family and the Cao family.
The Zheng family and the Cao family were originally neighbors, and the water from the two wells did not violate the river water, and they got along peacefully.
There was originally a vacant land between the two families, but when the village divided the land, due to negligence, the vacant land was not divided to anyone, so the land was always empty.
Later, the Cao family began to do business abroad, catching up with the good times, coupled with the flexible mind of the Cao family, which made the Cao family make a lot of money abroad.

When they returned home for the New Year, the Cao family drove home in a luxury car, wearing new clothes, and carrying a large number of gifts. This made the next-door neighbor Zheng family look at it and envy it in their hearts.
Soon, the villagers also discovered the changes in the Cao family, from a poor and white dilapidated family to a large family with clothes and brocade returning to their hometowns, and the story of the Cao family also became a talking point for the villagers in Wuyun Town after tea and dinner.
When visiting the door for the New Year, they went to the Cao family to congratulate him, which also made the vanity of the Cao family quickly satisfied.
Just as the so-called people rely on clothes and horses on the saddle, the Cao family under the accumulation of wealth gradually has their own right to speak in the town, and gradually becomes horizontal.
The children of the Cao family fought and made trouble, and the Cao family also connived and acquiesced, and the people in the town could only endure it silently because of the power of the Cao family.
Soon the Cao family turned their attention to the vacant land, and they could not think of a penny to build a house on the vacant land, and they said they would do it, and the next day they hired workers to start construction.
The sound of workers building quickly alarmed the neighbor Zheng family, which made the Zheng family very angry, this vacant land is between the two families, why should the Cao family take it for themselves?
Zheng Yongjun of the Zheng family stood up and stopped the construction workers on the spot. Although Zheng Yongjun did not have much wealth, he was strong and had developed limbs, and the construction workers were afraid of conflict, so they immediately called the Cao family.
And the Cao family refused to show up, and they did not put their neighbors Zheng family in their eyes at all.
So Zheng Yongjun repeatedly took people to make trouble at the construction site, and the Cao family finally stopped working.
In the process of negotiating with the Cao family, Zheng Yongjun also felt a deep sense of powerlessness, his family had no money and power, let alone no one to support him, and it was so difficult to get justice after being bullied.
After watching the Cao family stop working, Zheng Yongjun decided to go out to work to earn money, and he advised his family not to have a frontal conflict with the Cao family when he was not at home.
But after Zheng Yongjun left, an accident happened.

The Cao family saw Zheng Yongjun go out to work, so they resumed the project. The Zheng family's mother went to reason, and the Cao family even scolded him.
The movement of the two families grew louder and louder, until it alarmed the village committee.
In order to settle the dispute, the village committee called the two families together to discuss dividing the vacant land into two, and the two families took half of it on average.
The Zheng family immediately agreed with the village committee's approach and agreed. But the Cao family was bound to get this open space, and they even did not hesitate to make a trick for this reason.
After that, the Cao family hired a few people to fill several large buckets full of dung and put them in the open space, because the open space was close to the Zheng family's kitchen, so as soon as the wind blew, the smell of feces spread into the Zheng family's kitchen.
The smell of summer feces is disgusting, which also makes the Zheng family miserable.
The Zheng family's mother once stepped forward to theorize with the Cao family, but the Cao family did not put this old woman in their eyes at all.
They told the Zheng family mother that the buckets of dung would remain here until they agreed to give up the vacant lot.
The Cao family's patience is limited, and if the matter is not resolved within a month, they will spill feces into the Zheng family's house, and the hatred between the two families will accumulate more and more.
Once, when the Cao family was shopping on the street, they accidentally saw the daughter-in-law of the Zheng family, and a group of people gathered around, speaking frivolously to the daughter-in-law of the Zheng family, just ready to step forward. The daughter-in-law of the Zheng family, who was also angry, went home and cried, and then informed the Zheng family's mother about it.
The mother of the Zheng family watched her daughter-in-law suffer in her own home, and she couldn't get angry, so she took her daughter-in-law and daughter to the Cao family theory. The Cao family looked at the three women and children in front of them and laughed wildly.
They beat and scolded the three women and children, and in the end, the Zheng family's mother was broken in her leg, and the daughter-in-law and daughter's body was also blue and purple.
After the daughter-in-law of the Zheng family sent her mother to the hospital, she could no longer bear it, and called her husband Zheng Yongjun, who was working far away in Shanghai, to tell Zheng Yongjun the truth, and Zheng Yongjun was angry and returned home overnight.
On the way home, he called his brother-in-law, Ding Kaiya, who was working as an assistant police officer.
The brother-in-law was also extremely angry when he heard that his mother-in-law and wife had been beaten. So, the two big men planned together to give the Cao family a little color.

On the night of August 1, 2011, the two pried open the door of the Cao family with kitchen knives, and Zheng Yongjun lost his mind, brandishing a kitchen knife at the Cao family and hacking and killing.
The Cao family was frightened and ran around, but Zheng Yongjun did not let any of them go.
When the villagers arrived, all the more than ten members of the Cao family fell to the ground, and the courtyard was full of blood. After being rescued by the hospital, three people died and seven were injured.
The police soon arrested Zheng Yongjun and his brother-in-law, Ding Kaiya. In late 2001, a local court sentenced Zheng to death. Ding Kaiya was sentenced to three years in prison.
The tragedy of the Cao family tells us that there will be rain when the sky is crazy, and woe to the madness of people, and we must not go too far in doing things and doing things.
