He stressed that we should take the comprehensive and strict governance of the Party as the long-term strategy and eternal topic of the Party at the height of the long-term governance of the Party, the long-term stability of the country, and the happiness and well-being of the people. We should always adhere to the problem-oriented, maintain strategic focus, carry forward the thorough self-revolutionary spirit, always play the trumpets of confrontation, persist in the strict tone, measures, and atmosphere for a long time, and carry out the great self-revolution of the Party to the end. Since then, "self revolution" has been mentioned many times. In the report of the 20th National Congress of the CPC, he solemnly declared that "the Party has found the second answer to the self-revolution, which jumps out of the historical cycle rate of the rise and fall of chaos". Qian Xiaoping said that the theory of self-revolution is an important part of the sinicized Marxist party building theory.

"Self purification" emphasizes to purify the Party's team and ensure the Party's physical health by removing viruses and tumors and filtering impurities; "Self improvement" emphasizes the priority of prevention, blocking the loopholes in the system, improving the supervision mechanism, and improving the Party's long-term governance ability; "Self innovation" emphasizes deeply grasping the development trend of the times and constantly opening up the future through reforming the old and renovating the new; "Self improvement" emphasizes strengthening party spirit training and political experience, constantly improving the political realm, ideological realm and moral realm, and comprehensively enhancing the ability to govern.

Deng Jingting, a professor at the Criminal Law Science Research Center of Renmin University of China, believes that self-revolution is embodied in the courage and courage of the Party to correct itself, which is essentially to adhere to the truth and seek truth from facts. If a century-old party and a ruling party want to jump out of the historical cycle of the rise and fall of chaos, they must constantly carry out self-innovation and self-revolution.
