Fighting and obstructing official duties are relatively minor. Generally, you can go out within 37 days. Whether you can go out will be judged according to the severity of the injury. If the time span is 3 to 3 years, it will be a group fight and serious injury. Generally, fighting lasts for 3 to 10 months. There are various criminal cases, mostly fighting and obstructing control, thieves and robberies, less murders, drug trafficking, fraud, and various economic cases. The environment changes a person. I couldn't imagine the feeling of being roasted before, but when you see everyone like that, you become numb. In fact, the detention center is not as scary as you think. It also has strict rules and regulations. It is impossible to bully you casually, as long as you don't cause trouble. But the food was really bad. I lost 7 pounds in the first week. I had white rice and pickled mustard for breakfast every day. The pickled mustard has no other taste except salty. On Tuesdays and Saturdays, I would add an egg. Lunch and dinner are basically a cycle of potatoes, cabbage, roasted bran, vermicelli, tofu, and kelp. The taste is simply unpalatable. Sleeping in Datongbu, each person has four and a half pieces of wood. If the person sleeping next to you is fat, that's unlucky. It's basically crowded. I'm unlucky. Although the person sleeping next to me is not fat, one of them is crazy. The reason she came in was because she stole a bunch from the fruit stand. Don't catch grapes and fight with the vendors. A lot of things happened to her later. Life there is indeed very regular. Without mobile phones and computers, everyone basically just chats to pass the time, which in turn shortens the distance between people.
