He stressed that we should improve the internal control mechanism, consciously accept the supervision of all aspects, strictly manage the discipline inspection and supervision cadres, strictly punish the corrupt elements in the system, and resolutely prevent and control the "black under the light". How to prevent "black under the light"? Professor Zhang Xiaoyu of the Central Party School (National School of Administration) said in an interview with China.com that the prevention and control of "black under the light" should be done in three aspects. First, we should firmly establish the thinking of rule of law in the whole process of discipline inspection and supervision. The basic thinking of rule of law, such as rules, procedures, evidence and restriction, is the fundamental way to prevent power corruption. The second is to further improve the system construction of discipline inspection and supervision, especially the system construction of case handling procedures and team construction. Although there are laws and regulations in the field of discipline inspection and supervision in China, such as the Supervision Law, the Law of Supervisors, and the Regulations on the Implementation of the Supervision Law, the relevant laws and regulations are not enough considering the extreme importance of discipline inspection and supervision. Third, we should further improve the division of labor and cooperation mechanism between discipline inspection and supervision organs, procuratorial organs and judicial organs. Discipline inspection and supervision organs should not only strengthen internal system construction and internal power restriction, but also accept external supervision and restriction. Qian Xiaoping, director of the Anti-Corruption and Rule of Law Research Center of Southeast University, pointed out that to prevent "blackness under the light", strict management of discipline inspection and supervision cadres includes internal supervision and external supervision. In terms of internal supervision, the first is to carry out supervision by comprehensively implementing the main responsibilities of the Party Committee and the discipline inspection and supervision organs. The second is to supervise through the organization and leadership mechanism of the discipline inspection and supervision organ. The third is to strengthen the construction of the internal control mechanism for case handling, and establish a full-process supervision mechanism in the aspects of case clue management, review and verification, case classification, and handling, to prevent improper interference in cases. In terms of external supervision, the first is the legal supervision and work supervision of the People's Congress over the discipline inspection and supervision organs. The Standing Committee of the People's Congress at all levels has the right to listen to and review the special work report of the supervisory committee at the corresponding level and organize law enforcement inspection. Second, the People's Court and the People's Procuratorate supervise the exercise of power of discipline inspection and supervision organs and public officials according to law by performing the trial and procuratorial functions entrusted by the Constitution and law. Third, other supervision. There are other forms of supervision over the discipline inspection and supervision organs and their staff, such as democratic supervision, social supervision and public opinion supervision, thus forming a three-dimensional supervision system. Qian Xiaoping stressed that compared with internal supervision, external supervision, especially the supervision of judicial organs, still has room for further improvement in the scope, strength and effect of supervision. To prevent "black under the light", Li Feng, associate professor of the Political and Legal Teaching and Research Department of the Central Party School (National Academy of Administration), believes that the role of the temporary Party branch can also be fully played. The review and investigation team is a temporary special organization that carries out work at the front line of supervision, discipline enforcement and law enforcement, with heavy tasks, wide contact with the society and concentrated power risks. Should be fully developed
