They are the cradle cultivating police. Strengthening basic construction of public security colleges and universities ,combining each aspect management and teaching work thus forming a perfect management system is the cornerstone promoting long-term development of public security education undertakings. Since 2011, Students＇ Affairs Office of Criminal Police College of China has developed and implemented basic construction programs, starting with students organizations at grassroots level, achievinv better results. It has certain reference significance for improving student management work in public security colleges.展开更多
