In the ten years of the new era, our Party has constantly deepened its understanding of the law of self-revolution, constantly promoted theoretical innovation, practical innovation and institutional innovation in Party building, and initially established a comprehensive and strict Party governance system. Marxist materialistic dialectics tells us that we should observe things and grasp the laws of development of things from the perspective of universal connection, comprehensive and systematic development and change. For our world's largest ruling party, which has been in power for more than 100 years, has been in power for more than 70 years, has more than 96 million party members, and has significant global influence, there are many unique problems that need to be solved, and faces major risks and serious challenges outside. Many problems are caused by a single occurrence. Only the "system" level focuses on efforts, and overall, not partial, systematic, not piecemeal Only by persistently, not transiently, and in a high standard, not in a general way, can our party always maintain its progressiveness and purity, and lead the towering ship of socialism with Chinese characteristics to break through the waves and forge ahead.

In terms of institutional structure, the "1+4" inner-party regulatory system under the Party Constitution, which is divided into the Party's organizational laws and regulations, the Party's leadership laws and regulations, the Party's own construction laws and regulations, and the Party's supervision and security laws and regulations, has been formed. It pays attention to the coordination, coupling and supporting of laws and regulations in all aspects, strengthens the implementation of the system, and gives play to its strong governance ability. At the same time, as a dynamic system, the system of comprehensive and strict governance of the Party is constantly developing and improving with the theoretical, practical and institutional innovation of the Party's construction. To build a comprehensive and strict party governance system, the key is to improve the "system". The "system" includes many levels, but the foundation is the system.
