The TV series Heaven hides traitors is adapted from a real case. The prototype of Changling City in the play is Changde City, Hunan Province, and the prototype of Zijiang City in the play is Yiyang City, Hunan Province.

According to Jianghu legend, this man is ruthless and resourceful, and controls the underground casinos in Hanshou and Yiyang. His men are absolutely loyal to him, and they don't know what methods he uses. Moreover, this criminal gang has a large number of military guns and ammunition, and they don't know where they got it. In order to train his men, Zhang Jun will take his men to grab a few people and take them to remote places every year to practice marksmanship and courage. Moreover, As long as you are attracted by Zhang Jun, he will try his best to draw you closer to his gang. The first thing to join his gang is to kill a person to show loyalty, which is a bit like the outlaw warlords.

I'm from Changde. I still remember clearly that the day when the case happened happened was the first day of my first year of high school. After school, I rode my bike home and saw a large number of people gathering from a distance. That kind of scene made me jumpy even now, as if there had been a great revolution. I have only seen this kind of scene on TV. The road for several kilometers was crowded with people and the traffic was paralyzed. I had to get off the cart and walk. I saw three bodies lying on the ground along the way. According to passers-by, they were extremely fierce. They wanted to grab a taxi, holding the driver's head in one hand and pointing a gun at the driver's head in the other. Moreover, Zhang Junyou has several men, all of whom are retired special police officers, and their marksmanship is extremely accurate. They are really a hundred paces, and someone is chasing him behind. He runs in front, and suddenly his backhand is a shot, which can hit the forehead of the person chasing him.
