秦城监狱
In July 2007, Chen was expelled from the Communist Party, and his case was transferred to judicial authorities. In comparison to the judicial action against Chen Xitong, Chen's case proceeded at a much faster pace. During the investigation, Chen was placed under house arrest in Qinhuangdao, where he lived in a mansion and spent most of his time playing cards and reading, ordering his meals from menus. Thereafter, Chen was transferred to Qincheng Prison in the Changping District of Beijing.
