History is a history of development, understanding, and ideological enlightenment; people use history to clarify ideas, develop ideas, and enhance understanding, and people also use history to get enlightenment, change concepts, and change practices to adapt to the general laws of historical development. A history of the development of socialism, that is, the history of ideology and understanding of the development of socialism, that is, the history of the development of the laws of social development; At the same time, it is also a history of people's understanding of socialism being further enhanced, reflected, sublimated and re-determined. Through the nearly 500-year history of socialist development, we can see that the development of a new thing has a historical development process from young immaturity to maturity; in this process, there are repetitions, setbacks, failures, and successes; everything is actually so normal, because the development law behind its things is at work, and history is so stumbling through the bumps and entering a new stage. Just as no two leaves in the world are the same, no country in the world follows exactly the same path of development. The reason why we embarked on the development path of socialism with Chinese characteristics is determined according to China's national conditions and historical development conditions, and is completely an inevitable choice for historical development. Today, socialism is no longer an empty noun concept, nor is it the object of criticism in the past, and the development of socialism, especially the vigorous development of socialism in China, is enough to shock the world, and it has forced many organizations and political forces in the world to dress themselves up as the image and supporters of socialism, and all declare that they are engaged in socialism. In such a complicated situation, the historical reality of the development of socialism tells us that we must clearly understand what socialism is and understand the history of the development of scientific socialism. History is a mirror that allows us to see many experiences and lessons from both positive and negative aspects of history, so that we know what to do, how to understand problems, and not to make the same historical mistakes; History is also a wake-up call, which tells us: There are some people who, in spite of the facts of history, the lessons of history, and the warnings of history, insist on going their own way, go their own way, and make the world unpeaceful and restless, then history must solemnly sound the alarm on its head and not let the tragedy of history repeat itself. History is even more a tool of struggle, and those who are hostile to socialism often start from history, change history, and engage in nihilism against the history of the Chinese revolution, in a vain attempt to negate the achievements of the Chinese revolution and the development of socialism by denying history. Only by understanding and respecting history is the history of development and the foundation for achieving social progress. History is still a kind old man who respects the law, it knows how to care, how to care, knows how not to let the weak suffer losses, knows how to let the new strength thrive, everything with development prospects, everything with vitality, no matter how weak it is at the beginning, will surely win support, win trust, win strength and win hope, it will surely move towards prosperity and strength, socialism is such a new thing, a new force, it is more a spiritual belief and a hope, no matter what storms and storms it encounters, Hardship and hardship, it will be inexorable and unstoppable. As a new thing, socialism has gone through a historical development process of nearly 500 years from the initial idea, ism, and trend of thought, to the later social movement, and then to the establishment of a socialist system, among which it has experienced the historical process of development from utopia to science, from theory to practice, from practice in one country to practice in many countries, experienced twists and turns in the development path, and also experienced brilliant and splendid development years. Therefore, socialism is also a historical development process of constantly meeting challenges, overcoming difficulties, and achieving victories. On the road of China's modernization and development, the reason why we chose socialism and take the socialist development path is the result of the painful choice made by the Chinese people in the course of the development of China's modern history since the Opium War in 1840, the choice of history and the people, because socialism represents the direction of the development of the times, and because only socialism can save China. Today, history has come to the 21st century, socialism has also ushered in new challenges and new development opportunities, especially socialism with Chinese characteristics, which has won the attention and expectations of the world, the development theory, development path and development system of socialism with Chinese characteristics chosen by the Chinese people and its great achievements have exerted great influence in the world, and also won the confidence of the Chinese people's road, theory and system, and the Chinese spirit, Chinese strength and China's rise have become an unavoidable topic of world history. A Chinese dream of the great rejuvenation of the Chinese nation is surging and rising on the land of China. General Secretary Xi Jinping pointed out that to realize the Chinese dream, we must take the Chinese road, carry forward the Chinese spirit, and unite China's strength. These three musts unify the three major elements of the Chinese road, Chinese spirit and Chinese strength for the first time, and they are a basic ruling principle for our party to lead the people to realize the Chinese dream of the great rejuvenation of the Chinese nation. In particular, taking the road of socialism with Chinese characteristics is a political prerequisite for realizing the Chinese dream. The unification of the path of socialism with Chinese characteristics with the Chinese dream is the process of realizing the Chinese dream, and the process of comprehensive development of China's economic construction, political construction, cultural construction, social construction and ecological civilization construction, which embodies the essential requirements of building a prosperous and strong China, a democratic China, a civilized China, a harmonious China and a beautiful China. This is the conclusion of history, this is the choice of the people. With the development of socialism in China for more than 60 years, especially the development of reform and opening up for more than 30 years, the socialist road has become broader and broader, and tremendous development achievements have been made that have attracted worldwide attention. Today, when we study socialist theory, take the road of socialism with Chinese characteristics, and build a socialist country, we must understand the history of the development of socialism; only by understanding the history of socialist development can we correctly understand and evaluate a series of problems facing the development of socialism, correctly face various challenges and difficulties in the development of socialism, and strengthen our ideals and convictions in socialism.
