Before you completely lose your freedom, sit cross-legged for 8 hours every day for 7 days, or you will be beaten. Sitting on the board, you have to recite dozens of prison rules and regulations and codes of conduct. If you can't recite them, you will be beaten and punished. Every day, the prisoners read aloud, "Good leader! Good director! Discipline well! A series of prison rules, such as conducting education, actively reforming, being frank and lenient, resisting strictness, being pro-government, being close to the people, changing from evil to good, turning over a new leaf, coming back from the brink, and "seriously studying national laws" ... "。

The prisoner should shout "report" before speaking, and the discipline should call you. You should shout "here" and don't talk to other prisoners. When you get out of the cell, you have to squat down and put on handcuffs. Every time you check the detention center, you should collectively lie on the wall, undress and search carefully. If you find prohibited items, you will be in trouble. I have to work hard, mop the floor and clean the toilet every day. You can only eat on the ground for 5 minutes. When you see discipline, you should hold your head down and feel inferior.

Some people come out of the detention center with chronic diseases, such as hepatitis A, hepatitis C, pneumonia, stomach trouble and eczema. Because the crowded environment and sanitation in the detention center cannot be guaranteed.

Sitting on the board for a long time will hurt your ass. Many people leave black cocoons on their buttocks and ankles when they come out. The suspect must be absolutely honest and dare not move casually.
