What should I do if I commit criminal responsibility and enter the detention center?

After interrogation and confession by the police, he was sent to the detention center. First, he stripped off his clothes and had a physical examination, especially to check if there was anything in his anus. He washed cold water and changed into the prison uniform of the detention center, shaved his head and entered the cell. I am 15 square meter cell for 25 people, which is very crowded. You can only bathe in cold water every day. When you first go in, you should take off your clothes and check the cold water disinfection of anus and genitals. I was forced to work on the back of the board, or I was beaten if I couldn't. I took off my pants and shoes and was spanked 500 times by the captain. You can't sit still for days, and you don't have enough to eat every day. Put your hands on your head during the interrogation, or you will be beaten. After the trial, go back to the cell and wait for the verdict.
