Senior discipline inspector Han Henglin has said that officials should fight corruption and other illegal conduct in China's prison system.
Han, chief of discipline inspection in the Ministry of Justice which oversees nationwide prisons, told his subordinates that the prison system faces "a severe and complicated situation" in the fight against corruption.
Abiding by the rules must be incorporated into daily administration, education and promotion of officials in the prison system, Han was quoted as saying by the Communist Party of China's (CPC) Central Commission for Discipline Inspection.
In 2014, discipline inspection agencies nationwide investigated about 50,000 cases of minor violations and punished more than 20,000 officials including high-level officials like former national security chief Zhou Yangkong and a number of senior military officials.
