1, political prisoner armor class is the highest and the living allowance is the best. They don't need to take part in labor. They can apply for a separate room, have a menu, don't wear prison clothes, watch closed-circuit television and read some censored newspapers, participate in sports activities regularly, and the prison regularly organizes physical examinations and the care of professional doctors. But the monitoring is very strict. You can't leave the prison staff's 24-hour surveillance range.
2. Economic criminals are paid less than political prisoners but more than criminals, and engage in mental or light manual labor. Wearing prison clothes and often exercising outdoors, the medical conditions are relatively acceptable and loose.
3. Criminals have the worst living conditions, engaged in heavy manual labor, no choice of food, wearing prison clothes, unable to walk freely, living in multiple cells and poor medical conditions.
