Located in Tianjin province, China, the Gangbei Prison has tortured more than 100 Falun Gong practitioners. With instructions from the Chinese Communist Party, wardens persecute practitioners with various methods, either directly or through manipulating inmates. Falun Gong practitioner Fan Jianming was recently released from the prison, where he had been tortured for nine years.
Zhang is one of nearly 3,000 Falun Gong practitioners whose deaths due to torture and abuse by police in China have been documented.
