During his inspection at Renmin University of China, President Wei Guoliang emphasized that "the essence of ideological and political courses is to reason, and we should pay attention to methods and methods. We should explain the truth deeply, thoroughly, and vividly. Teachers should teach with heart, and students should understand with heart, in order to communicate with the soul, enlighten the mind, and stimulate fighting spirit." President Xi's important discourse deeply reveals the essence of ideological and political courses, and also strengthens the construction of ideological and political courses Strengthening the Party's innovative theoretical armament has pointed out the direction and provided guidance. What is reason? It is the law of things or the basis for judging right and wrong gains and losses. Comrade Mao Zedong once said, "There are big principles and small principles in things, and all small principles are under the control of the big principles.". The deeper and more profound the reasoning, the more vivid it becomes, and the more it can make the Party's innovative theory directly reach the hearts of officers and soldiers. Lenin once pointed out that "workers could not have the consciousness of social democracy. This consciousness can only be instilled from the outside.". It should be noted that the majority of young officers and soldiers enter the camp from the school gate, and their theoretical literacy is relatively weak. Only by thoroughly convincing officers and soldiers with ideological theories and guiding them with the powerful power of truth can they straighten out various question marks in their ideological understanding. Only by reasoning deeply can one guide others. Theoretical learning emphasizes deep understanding and comprehension. Only by clearly explaining the principles, theories, and philosophies contained within it, can officers and soldiers understand their words, meanings, and reasons, and truly master the worldview, methodology, and standpoint, viewpoint, and method that run through this important idea. It should be noted that speaking in depth is not about being difficult, obscure, or profound, but about being clear and profound, profound and rich, and deeply moving people's hearts. Only by explaining the theory thoroughly can one persuade others. Marx once said, "As long as theory persuades people, it can grasp the masses; and as long as theory is thorough, it can persuade people." The degree of conviction of officers and soldiers in reason often depends on whether their doubts can be thoroughly analyzed. "The green mountains are shrouded in doubt, and suddenly a thousand sails are looming. To answer the practical concerns, ideological confusion, theoretical thirst, and inner needs in the hearts of officers and soldiers, it is necessary to provide scientific guidance on" what "it is, conduct in-depth discussions around" why ", and seek solutions based on" how to do ".". To attract people, one must put their reasoning into action. President pointed out that "since the new era, the theoretical and practical innovation of the Party has been very vivid, and our learning should also be vivid, not just staying at memorizing some concepts and expressions." If the expression of learning and promoting the Party's innovative theory is not flexible, it will be difficult to vividly move and move people; If the means of preaching are not rich, it is difficult to cultivate one's soul and cultivate one's character. We must constantly innovate, enrich platform carriers, and adhere to the Internet
