On the first 10 day, sit cross-legged for 8 hours every day, don't move, or you will be beaten. Sitting on the board, you have to recite dozens of prison rules and regulations and codes of conduct, and you will be punished if you don't recite them.
Sitting on the board for a long time will hurt your ass. Many people will leave a black mark on their ass when they come out. The suspect must be absolutely honest and dare not move casually. The detention center has no freedom at all, and you have to shout for a report when you pee. You can't go to the toilet without permission. Everyone must work under compulsion. Every day 10- 12 hours, more than 20 people live together, and the urine is also in the cell, which stinks. Generally do lighters, wallets, handicrafts processing. If you can't finish the work, you will be punished and you will try your best to finish it. You are afraid of being beaten and not having enough to eat. You cook cabbage every day, and the conditions are very poor.
