1. Physical environment: southern prisons usually consist of buildings and walls to limit the inmates' range of motion. Buildings within prisons include cells, cafeterias, exercise areas, classrooms, etc. These facilities provide the basic necessities of life and work. Cells are usually single or multiple occupancy, depending on the circumstances.
2. Security measures: Prisons have security measures in place to ensure the safety of inmates and prison staff. For example, prisons usually have security cameras, steel doors, and security screening equipment for monitoring and restricting inmate movement. In addition, prisons conduct regular patrols and security drills to address potential threats.
3. Daily life: Southern prisons provide basic daily living facilities and services such as food, medical care, spiritual counseling, and educational opportunities. Inmates will usually work, study and rest on a set schedule.
It is important to note that specific prison environments vary from region to region and from particular prison to particular prison. Each prison has its own administrative rules and regulations and security measures that are designed to maintain order and protect the safety of inmates and staff. If you are interested in the environmental conditions of a specific prison, I recommend that you check the public reports of the relevant prisons or consult the relevant organizations.
