As the latest achievement of the sinicization and modernization of Marxist civilization, the modern civilization of the Chinese nation contains a rigorous and complete independent knowledge system, endowing Marxism with a deeper historical foundation and richer cultural heritage. The proposal of this major proposition has deepened our understanding of the laws of socialist cultural construction with Chinese characteristics, the development of Chinese civilization, and the development of human civilization. The Theoretical Connotation of the Modern Civilization of the Chinese Nation In October 2022, when inspecting the ruins of Yin Ruins in Anyang, Henan Province, the state leaders clearly put forward the important proposition of "building the modern civilization of the Chinese nation". In June 2023, national leaders deeply elaborated on the new era and new cultural mission of "continuing to promote cultural prosperity, building a strong cultural country, and building modern Chinese civilization at a new starting point" at the symposium on cultural inheritance and development. In terms of theoretical connotation, the modern civilization of the Chinese nation is a socialist civilization led by the CPC, a civilization rooted in the excellent traditional Chinese culture, with the subjectivity of Chinese culture, and a civilization that draws on and absorbs all the outstanding achievements of human civilization. To promote the research and interpretation of the chemical, physical, and chemical aspects of the modern civilization system of the Chinese nation, we must adhere to the principles of not forgetting the original, absorbing foreign elements, and facing the future. We must take the Marxist concept of civilization as the essential norm, the excellent traditional Chinese culture as the background, and the exchange and mutual learning of civilizations as the development path. The modern civilization of the Chinese nation is a socialist civilization with distinctive Chinese characteristics, which is jointly created by the people of the whole country under the leadership of the CPC. In the academic history of civilization research, Marx is an indispensable intellectual monument. Although he has not conducted specialized civilization research, his contemplation on civilization issues runs through his life. If capital logic plays a dominant role in the development of Western civilization, then the internal logic followed by the construction of modern Chinese civilization is the sinicization and modernization of Marxism. As Marx pointed out, "Where history begins, the process of thought should also begin.". The modern civilization of the Chinese nation has achieved the unity of history and logic in the process of combining the basic principles of Marxism with China's specific realities and with the excellent traditional culture of China. The essence of the modern civilization of the Chinese nation is the socialist civilization led by the CPC, which sublates the western civilization and its capital logic. The most important aspect of studying and interpreting the modern civilization of the Chinese nation is to adhere to the principles of integrity and innovation, and to uphold the essence of the soul, neither following the closed and rigid old path nor the evil path of changing flags and flags. The reason why Marxism can take root and bear fruit in China is, in the final analysis, that the CPC people combine the position, viewpoint and method of Marxism with Chinese history, Chinese culture and Chinese practice to form a sinicized and contemporary Marxism, and use its scientific world outlook and methodology to solve China's problems, and constantly "let Marxism speak Chinese", opening up a new realm for the development of Marxist civilization. The modern civilization of the Chinese nation is rooted in the excellent traditional culture of China and has the subjectivity of Chinese culture, with Chinese excellent traditional culture as the background. The Chinese civilization is the only civilization among the major civilizations of humanity that has not been interrupted and has continued to this day. In recent years, several major projects such as the Chinese Civilization Exploration Project have further confirmed the million year human history, ten thousand year cultural history, and more than five thousand years of civilization history of the Chinese nation. Since modern times, the Chinese nation, which has created a brilliant civilization, has encountered a profound crisis of national humiliation, people's suffering, and civilization dust. Once Marxism was introduced to China, it activated the excellent genes of Chinese civilization with its thorough scientific, people-oriented, practical, and open nature, leading the life renewal and modern transformation of Chinese civilization, and completing the leap from tradition to modernity. The modern civilization of the Chinese nation is rooted in its own country and the fertile soil of its own historical and cultural heritage, endowing the Marxist concept of civilization with the form of the Chinese nation and achieving the metabolism of civilization. The research and interpretation of the modern civilization of the Chinese nation must strengthen cultural confidence, maintain its roots, and elevate cultural subjectivity. With cultural subjectivity, there is a steadfast self in the cultural sense, and cultural confidence has fundamental support. Only by adhering to the principles of upholding integrity and respecting the past without restoring it, and through creative transformation and innovative development of excellent traditional Chinese culture, can we make use of the past for the present, innovate and open up bright prospects for a new future of Chinese civilization. The modern civilization of the Chinese nation is a civilization that draws on and absorbs all the excellent achievements of human civilization, and takes cultural exchange and mutual learning as its development path. Civilization becomes richer and more colorful due to inclusiveness. An open attitude and inclusive mindset are the sources of vitality for the development of civilization. The prosperity of culture and the progress of civilization cannot be achieved without seeking common ground while reserving differences and being inclusive. The modern civilization of the Chinese nation has a profound ideological foundation in absorbing all the outstanding achievements of human civilization. Marxism is not a closed theoretical system, but a constantly developing and open theoretical system. The Chinese civilization has always maintained an open and inclusive attitude towards foreign civilizations, and various outstanding achievements of human civilization have enriched the spiritual world of the Chinese nation. Although Marxism and excellent traditional Chinese culture have different origins, they both have a high degree of compatibility and openness, which fundamentally determines the modern civilization of the Chinese nation nurtured by the "soul vein" of Marxism and the "root vein" of excellent traditional Chinese culture in the practice of Chinese social history. With an open and inclusive attitude, they exchange and learn from other civilizations around the world, adhere to the beauty of beauty, beauty and cooperation, and jointly prosper the world civilization garden. The research and interpretation of modern Chinese civilization must adhere to an open and inclusive attitude. Only by actively absorbing and drawing on all the excellent achievements of civilization created in human history, and achieving self centeredness and utilization, can we draw on excellent ideological and cultural resources from the sum of human knowledge. The modern civilization of the Chinese nation contains a rigorous and complete system of independent knowledge. The essential normativity of Marxist civilization view, the background of excellent traditional Chinese culture, the internal logic of "two combinations", and the development path of civilization exchange and mutual learning have all constructed the independent knowledge system building of modern Chinese civilization. The modern civilization of the Chinese nation is essentially a socialist civilization facing modernization, the world, and the future. It is a national, scientific, and popular civilization. It has achieved integration with the Chinese characteristics, essential requirements, and major principles of Chinese path to modernization, and is consistent with the core mentality, value pursuit, and development goals of Chinese path to modernization. It is the latest achievement of the sinicization and modernization of the Marxist concept of civilization. The modern civilization of the Chinese nation endows Marxism with a deeper historical foundation. The modern civilization of the Chinese nation adheres to and develops historical materialism. Historical materialism, as an important component of Marxist philosophy, reveals the essence and laws of historical movements from the long river of human development. The modern civilization of the Chinese nation adheres to the Marxist worldview and methodology, focusing on the overall situation and starting from the overall situation in terms of history, grasping the essence, direction, and mainstream, adhering to the analysis method of basic social contradictions, adhering to material production as the foundation of social life, and adhering to the position that the people are the creators of history, which is the modern form of Chinese civilization. The modern civilization of the Chinese nation endows Marxism with a deeper historical foundation. National leaders pointed out that "establishing a grand historical perspective, analyzing the evolution mechanism and exploring historical laws from the long river of history, the tide of the times, and global storms, proposing corresponding strategic strategies, and enhancing the systematic, foresight, and creativity of work.". The modern civilization of the Chinese nation connects history, reality and future. It has come from more than 10 years of great changes in the new era, from more than 40 years of great practice of reform and opening up, from more than 70 years of hard work in the founding of the People's Republic of China, from more than 100 years of tireless struggle in the founding of the CPC, from more than 180 years of Chinese national uprising since modern times, from more than 500 years of arduous exploration of world socialism, from more than 5000 years of inheritance and development of the Chinese nation's long civilization, and from the integration of Chinese excellent traditional culture, revolutionary culture, and advanced socialist culture. It has pointed out the direction for us to understand the laws of history, grasp the historical trend, seize historical opportunities, and keep up with the trend of the times. The modern civilization of the Chinese nation is based on the magnificent 5000 year history of Chinese civilization in terms of historical perspective, deeply elucidating the historical inevitability, cultural connotations, and unique advantages of the Chinese path, giving the path of socialism with Chinese characteristics a broader and more profound historical depth. It allows us to know its origin, identify its location, and understand its direction, without being blinded by the complex and diverse historical phenomena. It is a concentrated embodiment of using the big historical perspective to scientifically analyze and view problems, providing us with ideological guidance and spiritual power to enhance historical consciousness and strengthen cultural confidence. The modern civilization of the Chinese nation endows Marxism with richer cultural heritage. The modern civilization of the Chinese nation adheres to and develops the Marxist concept of civilization. Engels once said, "Civilization is a matter of practice and a quality of society." The Marxist concept of civilization deeply ponders the internal logic of civilization evolution, the structural levels of civilization systems, the historical forms and inevitable trends of civilization development from the perspective of human social historical development. In his later years, Marx proposed that backward countries and ethnic groups could cross the "Kaftin Canyon" of the capitalist system and possess all the achievements of civilization created by the capitalist system. He came to the important conclusion that Eastern civilization could completely embark on a development path different from Western civilization. The CPC led the Chinese people to open up a path of socialism with Chinese characteristics, and transformed Marxism's judgment on the inevitable trend of civilization development from theory to reality, which proved the scientific truth of the Marxist concept of civilization. The construction of modern civilization of the Chinese nation is rooted in the fertile soil of Chinese civilization and the construction of new era civilization, and has achieved a series of theoretical innovations and practical creations. The modern civilization of the Chinese nation endows Marxism with a richer cultural heritage. The state leaders pointed out that "only by comprehensively and deeply understanding the history of Chinese civilization can we more effectively promote the creative transformation and innovative development of China's excellent traditional culture, more vigorously promote the construction of socialist culture with Chinese characteristics, and build the modern civilization of the Chinese nation." The "Five in One" overall layout of the cause of socialism with Chinese characteristics requires that the construction of material civilization and spiritual civilization should be coordinated, and Chinese path to modernization should be promoted with new quality productivity. This urgently requires us to accelerate the construction of the cultural form of Chinese path to modernization and the construction of the modern civilization of the Chinese nation. The modern civilization of the Chinese nation is a great creation led by the Party to promote the "two combinations" in the new era. It breaks the cultural revisionism and cultural conservatism that do not distinguish and inherit traditional culture, breaks the complete westernization of Chinese history and culture, and blindly worships Western civilization. It refutes various Western centric civilization views such as the "end of history theory" and "civilization conflict theory", and scientifically answers a series of major issues such as "how different civilizations coexist" and "where human civilization goes" through cultural exchange that transcends cultural barriers, mutual learning that transcends civilization conflicts, and tolerance that transcends civilization superiority. It further enriches and develops the Marxist civilization view. The modern civilization of the Chinese nation connects Chinese civilization, socialist civilization, and human civilization in terms of civilization concept, forming a large pattern, broad vision, and grand atmosphere, demonstrating the inclusiveness of Chinese culture towards world civilization
