秦城监狱
Dai Qing, a famous Chinese human rights activist jailed at Qincheng Prison recalls that there is another type of interrogation room in which the stool is replaced by a chair and there is carpet on the floor. Additionally, there is air conditioning in the room. During the Cultural Revolution, before the interrogation had begun, everyone in the room had to read some quotes from Mao's Little Red Book loudly, and these quotes are also posted on the wall.
