秦城监狱
Qincheng Prison has been under the administration of the 13th Bureau of the Ministry of Public Security most of the time since its establishment. Beginning in late October 1967, it came under the control of the People's Liberation Army which at this point had been put in charge of the 13th Bureau by the Central Cultural Revolution Group and Zhou Enlai. The "Military Control Commission of the 13th Bureau" administered the prison until April–June 1969 when the Bureau itself was abolished. The administration of Qincheng Prison now became the responsibility of a "Military Control Commission of Qincheng Prison" which reported to the Beijing municipal Bureau of Public Security Military Control Commission and "not" to the Ministry of Public Security. Thus formally "downgraded" in administrative terms, Qincheng was until the end of 1972 referred to in public documents as the Seventh Brigade of the Military Commission of the Beijing Bureau of Public Security. The Ministry of Public Security reasserted control over the prison in early 1973, after a decision to this effect had been taken by Premier Zhou Enlai on 8 January of that year.
