Prisoners will work in factories, mines, aquaculture farms and other places. These jobs are hard and tiring. Some prisoners will be assigned to specific posts according to their own specialties, such as locksmith, electrician, lathe worker, milling worker, maintenance worker, shoemaker, sewing worker, construction worker, etc. The prison will also provide ideological, cultural and technical education to criminals to help them transform into law-abiding citizens. In prison, prisoners also have rest time, so they can do all kinds of leisure activities and read books.
