"Insisting on cultural self-confidence" in educational reform embodies a belief, a pursuit and a persistent spirit. Specifically, in order to adhere to cultural self-confidence in educational reform, it is especially necessary to highlight cultural consciousness, cultural introspection, cultural self-improvement and cultural responsibility in educational reform. The education of "four self-confidences" should face up to three kinds of questions that teenagers usually ask and solve doubts and doubts in a convincing way. To be clear, young people should not only have personal confidence, but also have the confidence of China, People's Republic of China (PRC) (PRC) and the Chinese nation as a member of the Chinese nation. Only the self-confidence of political parties, nationalities and countries can actively participate in the practice of creating a better life; Only with road confidence can we maintain strategic strength and avoid making subversive mistakes in practice; Only by theoretical self-confidence can we grasp the law and guide practice with scientific theory; Only when the system is self-confident, can we obtain the fundamental guarantee for China's development and progress and provide China's plan for mankind to explore a better social system; Only cultural self-confidence can enhance the spiritual strength of the people of the whole country and provide inexhaustible motive force for realizing the great rejuvenation of the Chinese nation. Contemporary young people have not experienced the complete process of poverty and weakness, internal troubles and foreign invasion, the primary stage of socialism and reform and opening up in old China. Therefore, it is not easy to understand the preciousness of Socialism with Chinese characteristics's achievements, and sometimes it is impossible to correctly treat social contradictions and problems such as the new economic normal, the widening gap between the rich and the poor, the deterioration of the ecological environment, and frequent corruption. In view of this situation, it is necessary to educate young people to observe the society from the viewpoint of universal contradiction, to look at problems from the perspective of development, and to make it clear that Socialism with Chinese characteristics's achievements are the mainstream and the essence, and the problems in development will ultimately be solved by development. Socialism with Chinese characteristics's insistence on road self-confidence, theoretical self-confidence, institutional self-confidence and cultural self-confidence is the most reasonable and well-founded person. How to have "four self-confidences" is actually how to view and evaluate Socialism with Chinese characteristics's road, theory, system and culture. To strengthen the "four self-confidences" education for teenagers, the most fundamental thing is to educate teenagers to pick up Marxist "binoculars" and "microscopes" and observe the world and analyze problems with Marxist world outlook and methodology. In order for teenagers to better adhere to the "four self-confidences", it is necessary to strengthen the education of dialectical materialism, historical materialism, Marxist political economy, the basic principles and methodology of scientific socialism, the coordinated education of the "five in one" overall layout and the "four comprehensive" strategic layout, and the education of the socialist core values and the "Chinese dream" for teenagers.
