The North Korean prison camps are unlike South Korean penitentiaries that are in the form of a building, but in the form of a closed village, surrounded at their outer perimenters by barber-wire fences punctuated with guard towers and patrolled by heavily armed guards. People in the camps get up at 5 a.m. and carry out their assigned labor from 5:30 a.m. They are extremely hard labored in mining, timber-cutting, or farming enterprises. There is no exception for children. School in the camp provide basic math, reading, writing etc., in the purpose of conducting labor, and students are forcibly labored.
