The correct thinking of people comes from practice, and practice unfolds in the long river of human development, which is both historical and practical. Practice has no end, and theoretical innovation has no end. And innovative theories that have been proven effective in practice also need to be truly mastered by the masses and transformed into material forces for transforming the world. Only by "learning the theory of truth" and "learning the theory of truth" can we rectify the root and cultivate the essence. To learn true theory, one must go back to basics. Extract powerful ideological weapons from accurately grasping worldviews, methodologies, and perspectives that run through them. The report of the 20th National Congress of the Communist Party of China put forward that "it is the solemn historical responsibility of the contemporary CPC people to constantly write a new chapter of the sinicization and modernization of Marxism. To continue to promote theoretical innovation based on practice, first of all, we must grasp the world outlook and methodology of socialism with Chinese characteristics for a new era, and adhere to and use the positions, views and methods that run through it".
