Comrade Xi Jinping pointed out that "the more our cause develops in depth, the more we need to constantly enhance our dialectical thinking ability." We should learn to master the fundamental methods of materialist dialectics, constantly enhance our dialectical thinking ability, and improve our ability to handle complex situations and complex problems. Learning dialectical materialism can not only increase knowledge, but more importantly, it has the guiding significance of methodology, which can enable us to continuously enhance the ability of dialectical thinking. It is very important for Party members, cadres, especially leading cadres, to promote their work, and for philosophers and social scientists to do a good job of research and speed up the construction of philosophy and social sciences with Chinese characteristics.

       Dialectical materialism hints at the correct way for philosophers and social scientists to study and research. Intensive reading of classics and thinking of classics should go hand in hand. Understanding dialectical materialism without classical works tends to lead to vulgarization and dogmatization. Intensive reading of classics is essential for learning and research. If intensive reading of classics is to grasp what the author writes, then thinking about classics is to understand why the author writes like this. Learning can accumulate knowledge, but it is necessary to think about how to transform knowledge into one's own. Intensive reading of classics and internalization of classics into the mind is a dynamic process of reflection, while thinking about classics is a prominent manifestation of initiative. Only by thinking can we comprehend and grasp the classics, and then internalize the classics into our own thinking ability. Only through the continuous cycle of intensive reading and thinking can book knowledge be transformed into their own thinking ability and understanding ability. To study Marxist classics, we should not only let our thinking sink into classics, strive to follow the inherent logic of classics, but also grasp the historical background, author's intentions, problem orientation and realistic value of the text, so as to form an overall grasp of the text. In the process of thinking, we should also pay attention to the combination of perceptual experience to understand ideas. After all, rational knowledge should be based on perceptual knowledge, and the continuous transition of rational knowledge can not be separated from the help of perceptual knowledge.

       Dialectical materialism reveals the correct direction of academic research for philosophers and social scientists. The academic advocated by Marxism is not academic for academic purposes, but emphasizes that academic research should serve the change of the world. Practicality is a distinctive feature of Marxist philosophy which is different from other philosophies. Marxist classical writers have a strong sense of criticism and problem, and often interpret their theoretical propositions in criticizing various wrong theories. For example, the basic viewpoints and principles of dialectical materialism are more and more clearly explained in Marx's criticism of Hegel and Feuerbach, Engels'criticism of Durin and Lenin's criticism of empirical criticism. Comrade Xi Jinping pointed out at the Symposium on philosophical and social sciences: "Theoretical innovation can only begin with problems. In a sense, the process of theoretical innovation is the process of finding, screening, researching and solving problems. The problem is the fulcrum of innovation in philosophy and social sciences. Only through this fulcrum can we effectively promote the construction of philosophy and social sciences with Chinese characteristics. People's problem consciousness is often subject to theoretical vision and value standpoint. What we call problem consciousness refers to the problem consciousness under the Marxist theory. Human society is constantly developing and changing, and new situations and problems emerge in endlessly. Any influential original research results are the result of thinking and studying the local prominent social problems at that time, and the product of answering the questions of the times. This requires philosophers and social scientists to creatively perceive and screen problems, actively set forward-looking subject innovation issues, and then concentrate on research and problem solving.

       Comrade Mao Zedong pointed out that "idealism and metaphysics are the most labor-saving in the world, because they can be blabbered by people, not based on objective reality, nor subject to objective reality." Strengthen investigation and research, accurately grasp the objective reality, ideologically there is a source of living water, in order to truly grasp the objective law. When Marx wrote Das Kapital, in order to write more than 20 pages of English labor law, he read the Blue Paper in the British Museum containing the reports of the British and Scottish Commission of Inquiry and factory inspectors. This enlightens the vast majority of philosophers and social scientists to learn and understand dialectical materialism and constantly enhance their ability of dialectical thinking, which requires great efforts and real efforts. It is necessary to strengthen investigation and research, widely possess materials and carefully identify relevant documents in order to make the collected data comprehensive and accurate. At the same time, a comprehensive review of past research results, the results of previous studies as the starting point and basis for their own research, careful review, carefully combed. Only in this way can we put forward systematic and valuable new ideas and opinions to guide new practice.
