"High security", that is, high security prison area, is commonly known as the strict management team in prison.

This is a place where prisoners are discouraged and cold. Once you enter the strictly managed team, the police who manage you are no longer ordinary police, but special police.

Usually, the prison area has enough activity space and colorful entertainment activities, but you are greeted by cold handcuffs, shackles and a palm-sized room in the strict management team.

High-security prisons mainly hold criminals with fixed-term imprisonment of 15 years or more, life imprisonment or death penalty with a two-year suspension.
