Prisoners have their own life time besides completing the prescribed things every day. Those who want to play ball and study, go to the library to read. This kind of life is quite boring. It's not like going out to drink, play or do anything. If you are inside, you must accept control and labor. Don't think that someone will give you food, sleep when you are full, and eat when you are full.
Many people want to enrich their lives, so they should be more active in lovesickness than others and strive for the opportunity of commutation. Therefore, many people will behave well in prison and strive for opportunities for performance, such as learning a professional knowledge and taking some certificates. I think the main thing is to see if a person's mind has changed, whether he is aware of the bad things he did before, and if he really repents, then he will know what to do every day.
What you do every day in prison, of course, depends on what crime you commit. Felony or life imprisonment is different from ordinary crimes and is subject to different controls. Generally speaking, accepting labor unions is the main job of prisoners in prison, followed by making ideological reports and attending education classes. Some prisoners can study hard in prison, put forward specific and useful measures for prison management, or apply for invention patents, and they can get reduced sentences and rewards.
Prison life is boring every day. Prisoners can get to know their cellmates, chat and exercise together, so that time will be faster. But after all, it is the loss of external stimulation, freedom and affection, which is the price that crime must pay.
