Since its birth, in guiding the workers' movement and socialist revolution, construction and reform, Marxism has made glorious achievements that have attracted worldwide attention, profoundly changed the world pattern and the development trend of human society, and revealed new development prospects for human society. Although opponents of Marxism have repeatedly claimed that Marxism is outdated, when the development of human society has a dilemma, people invariably return to Marx's ideological resources to seek inspiration to solve the dilemma, and the socialist system guided by Marxism has also gained new vitality and vitality after suffering setbacks. In a certain sense, the reason why contemporary capitalist society can get rid of the curse of the past periodic economic crisis is also due to the profound critique of the capitalist system by Marxism. Whether it is the efforts of European capitalism to overcome the economic crisis in the mid-to-late 19th century, or the hot sales of Marxist works in the Western world after the world financial crisis in 2008, whether it is the phenomenon of Marx being rated as the "first thinker of the millennium" by Western intellectual circles, or whether Marxism is constantly denigrated by his enemies, all of them show the great ideological influence and lasting vitality of Marxism. The tremendous ideological influence and lasting vitality of Marxism come from its scientific nature and truth. As General Secretary Xi Jinping pointed out in his speech at the Symposium on Philosophy and Social Science Work, "Although Marxism was born more than a century and a half ago, history and reality have proved that it is a scientific theory and still has strong vitality. Marxism profoundly reveals the universal laws of nature, human society and the development of human thinking, and points out the direction for the development and progress of human society. Marxism adheres to the position of realizing the liberation of the people and safeguarding the interests of the people, and takes the realization of free and comprehensive development of human beings and the liberation of all mankind as its own responsibility, reflecting mankind's beautiful vision of an ideal society; Marxism reveals the essence, internal connections and laws of development of things, and is a 'great tool for understanding' and a powerful ideological weapon for people to observe the world and analyze problems; Marxism has a distinct practical character and is committed not only to scientifically 'explaining the world', but also to actively 'changing the world'. In the history of human thought, no theory has had such a broad and tremendous impact on the progress of human civilization as Marxism." Marxism does not exhaust the truth; it continues to develop with the development of the times and the development of human practical activities. As a scientific world outlook and methodology, and as a "great tool for understanding," Marxism must constantly face the challenges of the development and changes of the times and answer major issues raised by different stages of historical development. In the era in which Marx and Engels lived, although bourgeois rule has been established in the major capitalist countries and the capitalist system is on the rise, the inherent contradictions of capitalist society have begun to be exposed, and the contradictions between the proletariat and the bourgeoisie have become increasingly apparent. Provide theoretical arguments for the replacement of the capitalist system by the socialist system. It was through the two great discoveries of the materialist view of history and the theory of surplus value that Marx realized the development of socialism from utopia to science, and provided a scientific guide and correct direction for the development of the workers' movement at that time. From the end of the 19th century to the 20s of the 20th century, the development of capitalist society reached a new stage, that is, the imperialist stage, the inherent contradictions of capitalist society showed new characteristics, due to the role of the law of unbalanced economic and political development of capitalism, the contradictions between imperialism sharpened, and human society entered a new era with war and revolution as the theme. Faced with the changes in the theme of the times and the new situation and new tasks facing the workers' movement, Lenin profoundly analyzed the changes in the basic contradictions of capitalist society in the imperialist stage, explored the main contradictions and laws of development in the imperialist period, profoundly revealed the historical inevitability that socialism can be the first to win victory in one country, led the Russian proletariat and the masses of the people to overthrow the tsarist autocracy, established the first socialist state in human history, and realized the great transformation of socialism from theory to reality. It has opened up a new era in human history and provided a brilliant example for future generations to uphold and develop Marxism. "The October Revolution sent us Marxism with the sound of a cannon." When Marxism was introduced into China, the Chinese nation was in danger of extinction and extinction, and Chinese society was in the abyss of a semi-colonial and semi-feudal society. Since the Opium War in 1840, ancient China has suffered "great changes unprecedented in 3,000 years"; groups of advanced Chinese have constantly explored the road to saving the country and the people; the foreign affairs movement promoted by enlightened people in feudal society has failed; the movement to restore and change the law launched by the bourgeois restorationists has not succeeded; the old-style peasant uprising launched by Hong Xiuquan and others has failed; and the bourgeois democratic revolutionary movement led by Sun Yat-sen and others has also died. After the introduction of Marxism into China, the outstanding elements of the Chinese nation who are struggling to find a way to save the country and the people have found new hope. The Chinese, represented by Li Dazhao, Chen Duxiu and others, began to study and propagate Marxism, and Marxism combined with the Chinese workers' movement to give rise to the Communist Party of China. However, how to achieve national independence, people's liberation, and then establish a socialist system in a semi-colonial and semi-feudal backward eastern country is a question that Marx, Engels and even Lenin have never encountered, let alone answered. This is a new and severe topic that history and the times have put forward for the Chinese Communists. In this regard, the Chinese Communists made painstaking explorations. The Chinese Communists represented by Comrade Mao Zedong conformed to the requirements of the times, integrated the universal principles of Marxism with China's reality, creatively promoted the Sinicization of Marxism, realized the first historical leap in the Sinicization of Marxism, and formed Mao Zedong Thought, the first major theoretical achievement of the Sinicization of Marxism. It was precisely under the guidance of Mao Zedong Thought that the Chinese people, through arduous efforts, overthrew imperialist colonial rule, established New China, realized national independence and people's liberation, and established the socialist system, laying a solid foundation for the progress of Chinese society and the development of the Chinese nation. The establishment of the socialist system has profoundly changed the basic structure and basic outlook of Chinese society and laid a solid foundation for the progress of Chinese society. However, in a large eastern country where the level of productive forces is very low, the rural population accounts for the overwhelming majority, and feudal traditions are deeply rooted, what kind of socialism to build and how to build socialism is another brand-new topic put forward by history and the times for the Chinese Communists. In this regard, the Chinese Communists have made unremitting theoretical and practical explorations, during which there have been setbacks, lessons, and joy of success. Since the beginning of reform and opening up, the Chinese Communists represented by Comrade Deng Xiaoping have adhered to the ideological line of seeking truth from facts, integrated the general principles of Marxism with China's reality, achieved the second theoretical leap in the Sinicization of Marxism, and formed a theoretical system of socialism with Chinese characteristics, including Deng Xiaoping Theory, the important thinking of the "three represents," and the scientific outlook on development. It is precisely under the guidance of the theoretical system of socialism with Chinese characteristics that China's socialist construction and reform has made great achievements that have attracted worldwide attention. History and practice have proven that upholding and developing Marxism is the fundamental guarantee for China's achievements in revolution, reform and construction. However, we must also be soberly aware that in the current era, with the in-depth development of economic globalization, political multipolarization, social informationization, and cultural pluralism, various contradictions and problems facing human society are unprecedentedly complex, the struggle in the ideological field is intensifying, and Marxism is also facing many new challenges. To uphold and develop Marxism, it is necessary to deeply study the basic tenets of Marxism, especially to thoroughly study and study the classic works of Marxism, to remove the fog imposed on Marxism, and to restore Marxism to its true form; To uphold and develop Marxism, we must also resolutely oppose the dogmatic and pragmatic attitude toward Marxism. Marxism is not a rigid dogma, nor is it a "treasure chest"; if we ignore changes in historical conditions, it is obviously not the correct attitude to treat Marxism by every sentence that a Marxist classic writer has said for a specific historical condition and a specific situation as a universal truth, and if everything must be found in the works of Marxist classic writers, Marxism as a whole should be tailored according to subjective needs, and arbitrary chapters and extracts from Marxist classic works. Nor is it the correct attitude towards Marxism; To uphold and develop Marxism, we must also continuously promote the Sinicization, modernization and popularization of Marxism, and persistently apply Marxist stands, viewpoints and methods to study and answer major theoretical and practical issues in China's reform, opening up, and socialist modernization; To uphold and develop Marxism, we must also make efforts to truly study, believe, understand, and apply Marxism; we must conscientiously study the classic works of Marxism, master the Marxist stand, viewpoint, and method, grasp the essence of Marxist thought, and consciously use the Marxist world outlook and methodology to analyze problems and guide practice. To uphold and develop Marxism, we must constantly deepen the theoretical study of Marxism. Since the beginning of reform and opening up, the central authorities have attached great importance to the study of Marxist theory, and have deeply promoted the research and construction project of Marxist theory, the construction of Marxist theoretical disciplines, and the construction of Marxist colleges. But as General Secretary Xi Jinping said, we "also have some comrades who do not have a deep understanding and understanding of Marxism, lack sufficient skills and high-level achievements in applying Marxist positions, viewpoints, and methods, and lack of skill and high-level achievements in building a discipline system, academic system, and discourse system guided by Marxism." There are also some vague and even erroneous perceptions in society. Some believe that Marxism is outdated, and China is not engaged in Marxism now; Some people say that Marxism is only an ideological preaching, and there is no academic rationality and systematization. In practice, in some fields, Marxism has been marginalized, generalized, and labeled, and in some disciplines it has been 'lost', in teaching materials it has been 'missing', and in forums it has lost its voice." Therefore, strengthening the study of Marxist theory is the unshirkable glorious mission of Marxist theoretical disciplines and philosophy and social science workers in colleges and universities. The School of Marxism of Northwest Normal University has a long history of running schools and a relatively deep academic accumulation, its predecessor is the Marxism-Leninism Teaching and Research Department established in 1953, and the Department of Political Education was established in 1959, and began to recruit undergraduate students majoring in ideological and political education. After the hard work of successive generations of scholars, it has now become an important Marxist theoretical discipline talent training and academic research base in Gansu Province, the college has two second-level discipline doctoral programs in Marxist basic principles and ideological and political education, a master's degree program in Marxist theory first-level discipline, has a postdoctoral research mobile station for Marxist theory, and Marxist theory discipline is a provincial key discipline in Gansu Province. The college has a faculty with a firm political stance, reasonable structure and high professional level, and has edited and published continuous publications of "Marxist Theoretical Research" in recent years. In order to further strengthen the construction of Marxist theoretical disciplines and improve the teaching and research ability of young and middle-aged teachers, the college organized young teachers to carry out scientific research and compiled this set of "Sinicization of Marxism" book series. It is hoped that the publication of this series of books will provide reference materials for teaching and research personnel and other readers of Marxist theory to study and study Marxism, and also hope to be criticized and corrected by experts and scholars.
