A glimpse inside a storied 120-year-old lockup

In 1999, the Shanghai Prison Exhibition Hall was set up in this building where historical materials and architectural models of some prisons in Shanghai and across the country are exhibited.

Over its years of operation, junior middle school education was provided universally among the prisoners, with some receiving senior middle school and college education. They obtained diplomas if they passed unified city-level exams. Technical and vocational training was also organized for the prisoners, and those who passed tests were issued graded certificates, said the prison officer.
