There is always a source for thousands of miles of rivers, and trees are thousands of feet high and have roots. General Secretary Xi Jinping pointed out that socialism with Chinese characteristics did not fall from the sky, but is a fundamental achievement made by the Party and the people through untold hardships and at great cost. Socialism with Chinese characteristics is the dialectical unity of the theoretical logic of scientific socialism and the historical logic of China's social development, and is a scientific socialism rooted in the land of China, reflecting the will of the Chinese people, and adapting to the requirements of the development and progress of China and the times.

Socialism with Chinese characteristics has been achieved through the great practice of reform and opening up over the past 40 years. After the Third Plenary Session of the 11 th CPC Central Committee, the Chinese Communists, with Comrade Deng Xiaoping as the main representative, re-established the ideological line of emancipating the mind and seeking truth from facts, thoroughly repudiated the erroneous theory and practice of "taking class struggle as the key link," carried out reform and opening up with tremendous political and theoretical courage, and successfully created socialism with Chinese characteristics. After the Fourth Plenary Session of the 13 th CPC Central Committee, the Chinese Communists, with Comrade Jiang Zemin as the main representative, defended socialism with Chinese characteristics in the face of the severe tests of the disintegration of the Soviet Union, the collapse of the Communist Party of the Soviet Union, the drastic changes in Eastern Europe, and the serious setbacks in world socialism, established the reform objectives and basic framework of the socialist market economic system, pushed forward the new great project of party building, and successfully pushed socialism with Chinese characteristics into the 21 st century. After the 16th National Congress of the Communist Party of China, the Chinese Communists, with Comrade Hu Jintao as the main representative, adhered to the path of scientific development, began to form an overall layout for building socialism with Chinese characteristics, focused on promoting the party's ability to govern and advanced nature, and successfully upheld and developed socialism with Chinese characteristics at a new historical starting point. Since the 18th National Congress of the Communist Party of China, the Party Central Committee with Comrade Xi Jinping at the core has not forgotten its original aspiration, kept its mission in mind, continued to struggle, coordinated and promoted the overall layout of the "five-in-one", coordinated the promotion of the "four comprehensive" strategic layout, unswervingly implemented the new development concept, and promoted historic changes in the cause of the Party and the country, socialism with Chinese characteristics has entered a new era, scientific socialism has radiated strong vitality and vitality in China in the 21st century, and the great banner of socialism with Chinese characteristics has been held high in the world. It has continued to write a new chapter in upholding and developing socialism with Chinese characteristics.

Socialism with Chinese characteristics has been achieved through continuous exploration nearly 70 years since the founding of the People's Republic of China. After the founding of New China, the Chinese Communists, with Comrade Mao Zedong as the main representative, led the whole party and the people of all nationalities throughout the country to creatively carry out socialist transformation and establish the basic socialist system on the basis of rapidly healing the wounds of war and restoring the national economy. There is no ready-made model to follow in how to build socialism in China, and this is a brand-new topic facing the party, and our party has made arduous explorations. In the course of studying and studying the course of socialist construction in the Soviet Union, our party soon became aware of the limitations of the Soviet model and proposed to take the Soviet Union as a mirror and independently explore a road of socialist construction suited to China's national conditions. Under the party's leadership, China has made tremendous achievements in socialist construction and has accumulated some valuable experience. However, due to the "leftist" mistakes in the party's guiding ideology for a period of time, many correct ideas on socialist construction have not been upheld and implemented, and even the "Cultural Revolution," which is a serious mistake of an overall nature and a long period of time, has occurred. Despite the difficulties and ups and downs in exploration, the positive results achieved by our party are extremely valuable, providing valuable experience, theoretical preparation, and material foundation for creating socialism with Chinese characteristics in the new historical period. Taking the Third Plenary Session of the 11 th CPC Central Committee as the historical period, our party led the people to carry out socialist construction, which is mainly divided into two historical periods: before and after the reform and opening up. These are two periods that are interrelated and have major differences, but in essence, they are both practical explorations in which our party leads the people to carry out socialist construction. Socialism with Chinese characteristics was created on the basis of the establishment of the basic socialist system and the construction of the People's Republic of China for more than 20 years, and the exploration of socialist practice before the reform and opening up has accumulated conditions for the exploration of socialist practice after the reform and opening up, and the exploration of socialist practice after the reform and opening up is the persistence, reform and development of the practice and exploration of the previous period.

Socialism with Chinese characteristics has been achieved through the practice of our party leading the people to carry out the great social revolution for more than 90 years. Since its founding, the Communist Party of China has regarded the realization of communism as the party's highest ideal and ultimate goal, shouldered the historical mission of realizing the great rejuvenation of the Chinese nation without hesitation, carried out a great social revolution with arduous and extraordinary hardships, and composed a magnificent epic of majestic mountains and rivers. Our party united and led the people to find a correct revolutionary path of encircling the cities with the countryside and seizing political power by force, waged a bloody struggle for 28 years, completed the new democratic revolution, established the People's Republic of China, and realized China's great leap from thousands of years of feudal autocracy to people's democracy. Since the founding of the People's Republic of China, our party has united and led the people to complete the socialist revolution, establish the basic socialist system, promote socialist construction, complete the most extensive and profound social transformation in the history of the Chinese nation, and realize the great leap of the Chinese nation from continuous decline in modern times to a fundamental reversal of destiny and continuous prosperity and strength. After the Third Plenary Session of the 11 th CPC Central Committee, our party united and led the people to carry out a new great revolution of reform and opening up, carried out a series of revolutionary changes in the socialist road, theory, system and culture, broke down all ideological and institutional obstacles that hindered the development of the country and the nation, opened up the road of socialism with Chinese characteristics, and opened a new era of socialism with Chinese characteristics, the great leap from getting rich to becoming strong. To uphold and develop socialism with Chinese characteristics in the new era, we must always maintain the revolutionary spirit and fighting spirit, continue to push forward the great social revolution that our party has led the people for more than 90 years, and strive to make socialism with Chinese characteristics show a stronger and more convincing force of truth.

Socialism with Chinese characteristics was achieved in the historical process of the Chinese nation from decline to prosperity for more than 170 years since modern times. After the Opium War in 1840, China suffered from the brutal aggression of the imperialist powers and the decadent rule of Chinese the feudal autocracy. The Chinese nation has never succumbed, and countless people with lofty ideals have followed one after another, exploring the way to save the country and the people, and carrying out singing and crying struggles. Sun Yat-sen proposed the "Three People's Principles" and led the Xinhai Revolution to success, ending the absolute monarchy that had ruled China for thousands of years. Due to the constraints of the historical process and social conditions, the Xinhai Revolution did not change the semi-colonial and semi-feudal social nature of old China, did not change the tragic fate of the Chinese people, and failed to fulfill the historical task of realizing national independence and the people's liberation. The October Revolution brought Marxism-Leninism to China with the sound of a cannon. From the scientific truth of Marxism-Leninism, the advanced elements in China see a way out for solving China's problems. Since its founding, the Communist Party of China (CPC) has united and led the people through countless difficulties and dangers, made great sacrifices, won the victory of the new democratic revolution, carried out socialist revolution and socialist construction, carried out a new revolution of reform and opening up and socialist modernization, and found, adhered to and expanded the path of socialism with Chinese characteristics. In the arduous exploration of socialism with Chinese characteristics, the Party has led the people to overcome one seemingly insurmountable difficulty after another, created one miracle after another in the annals of history, and ushered in a bright future for the great rejuvenation of the Chinese nation.

Socialism with Chinese characteristics is the result of more than 5,000 years of inheritance and development of Chinese civilization. The excellent traditional Chinese culture is the "root" and "soul" of the Chinese nation, the outstanding advantage of the Chinese nation, and the cultural root and source of civilization of socialism with Chinese characteristics. For more than 5,000 years, the continuous and profound Chinese culture contains the most fundamental spiritual genes of the Chinese nation, and is the rich nourishment for the Chinese nation's endless growth and development. The outstanding elements of traditional Chinese ideology and culture have played a very important role in the formation and continuous development of Chinese civilization for thousands of years without interruption, in the formation and maintenance of the political situation of China's unity and unity, in the formation and enrichment of the spirit of the Chinese nation, in encouraging the sons and daughters of China to safeguard national independence and resist foreign aggression, in promoting the development and progress of Chinese society, and in promoting the balance of social interests and social relations in China. At the same time, the rich philosophical thoughts, humanistic spirit, and traditional virtues of China's excellent traditional culture are important sources of ideas for solving the common problems faced by contemporary mankind, and provide useful inspiration for global governance and governance. Excellent traditional culture is the foundation of the inheritance and development of a country and a nation, and it must be creatively transformed and innovatively developed, so that it can become a valuable resource for upholding and developing socialism with Chinese characteristics in the new era.

By understanding the historical origins and development and evolution of socialism with Chinese characteristics, we can understand how our party has historically chosen Marxism and the socialist road through repeated comparisons and summaries in the process of promoting revolution, construction, and reform. how did they integrate the basic tenets of Marxism with China's reality and the characteristics of the times, and independently follow their own path? How did they go through untold hardships and pay a huge price to create and develop socialism with Chinese characteristics? Only socialism can save China, and only by upholding and developing socialism with Chinese characteristics can we achieve the great rejuvenation of the Chinese nation.
