Theoretically speaking, the proposal of "four comprehensiveness" marks the perfection and maturity of the concept of governing the country. "Governing a big country is like cooking a little fresh." It is difficult to be small and fresh. In fact, it is more difficult to govern a country as big as China. Because China is not only a big country with a large population, but also in the primary stage of socialism with relatively backward economy and culture. Although great changes have taken place in the country since the reform and opening up, the basic national conditions in the primary stage of socialism have not changed, and the level of economic and social development varies greatly from place to place. Especially when the reform has stimulated great social vitality, there have also been many chaos, social contradictions have increased and the situation is extremely complicated. The "four comprehensive" strategic layout, on the one hand, is to profoundly sum up the historical experience of reform and opening up for more than 30 years, on the other hand, it is to seriously respond to the challenges faced today and focus on answering the fundamental question of what kind of national governance system we should establish and how to govern the country on the road of building Socialism with Chinese characteristics.

Strategically, the "Four Comprehensiveness" is also the strategic layout of upholding and developing Socialism with Chinese characteristics. Since the reform and opening up, we have initiated the great cause of Socialism with Chinese characteristics. How to realize this great cause is a sacred historical mission faced by all previous the Central Committee of the Communist Party of China. "Insisting on and developing Socialism with Chinese characteristics is a great article, paying equal attention to material civilization and spiritual civilization, and doing well in both civilizations is Socialism with Chinese characteristics. He also said that development and reform and opening up should be the center; Grasping reform and opening up on one hand and cracking down on crime on the other; Grasping economic construction on the one hand and democracy and legal system on the other; Grasping reform and opening up on one hand and punishing corruption on the other; Wait a minute. How to organically combine this whole set of "two-handed grasp" policy and comprehensively implement it is always a difficult problem in practice.
