The historical progress of China in the 20th century is the result of the joint action of objective and subjective factors, external and internal factors, and historical logic and people's power are the fundamental factors. The China * * * production party complied with and mastered the historical laws, and played a vanguard, organization and leadership role. In this sense, it can be said that the historic progress of China in the 20th century was made under the leadership of China's * * * production party. China * * * production party follows the law of social development, formulates the line, program, principles and policies in line with China's national conditions, and strives to put them into practice, which points out the direction for the historic progress of the Chinese nation in the 20th century. Over the past 80 years, the China * * * production party has also fallen a lot and made many mistakes. However, having learned the lessons of setbacks, our Party has more firmly adhered to the scientific ideological line, thoroughly studied the national conditions of China, combined the truth of Marxism with the reality of China, and constantly explored the road of revolution and construction in practice. During the period of the new-democratic revolution, the line and program of the new-democratic revolution led by the proletariat and based on the alliance of workers and peasants against imperialism, feudalism and bureaucratic capitalism were formulated by the masses. After the founding of People's Republic of China (PRC), our party creatively opened up a socialist transformation road suitable for China characteristics. On the basis of establishing the basic socialist system, we have constantly explored the laws of economic construction, political construction and cultural construction, formulated a series of principles and policies, and gradually established an independent and relatively complete national economic system. There have been serious mistakes in the line, principles and policies, but our party itself has recognized and corrected the mistakes and formulated the major policies of reform and opening up, which has brought new vitality and vigor to China. Under the guidance of Deng Xiaoping Theory, we have formulated the basic line and basic program for the primary stage of socialism, formulated a "three-step" development strategy to basically realize socialist modernization, formed a blueprint for building Socialism with Chinese characteristics, and initially grasped the laws of building socialism in countries with relatively backward economy and culture. It is with these great theories, routes, strategies and blueprints that the development of China society has a direction. As the vanguard of the working class, China's * * * Production Party has played a powerful role in organizing and leading, changed the fragmented situation of China, closely United the people of the whole country, and worked hard to promote the historic progress of the Chinese nation. Looking back on the history of China's beating, humiliation and continuous wars in modern times, people can't help but think of such a question: Why did a huge ancient empire fail to resist the attack of foreign colonists, so that so many unequal treaties were signed? Why did so many warlords scuffle in the unified territory, causing countless wars and destruction? Why are there so many foreign forces looking for and manipulating their agents in China, and staged scenes of intrigue? The reasons are, of course, the decline of the system, the decay of politics, the weakness of the economy, the backwardness of science and technology and so on. But the disintegration of the people is undoubtedly one of the important reasons or manifestations. In order to completely change the face of China, we must unite all the people and the whole Chinese nation. Who can bear such responsibility? Different classes, different political parties, different social groups, different political forces and different people have tried and worked hard, but who succeeded in the end? No, only under the leadership of the * * * production party in China, people's unity and national unity were realized nationwide (except in Taiwan Province Province), which fundamentally changed the fragmented situation of old China. Through the establishment of a socialist country under the people's democratic dictatorship led by the working class and based on the alliance of workers and peasants, the great unity of workers, peasants, intellectuals and other people from all walks of life has been realized; Through the implementation of the unified national structure and the system of regional ethnic autonomy, 56 ethnic groups have formed socialist ethnic relations of equality and mutual assistance and achieved great unity among the people of all ethnic groups throughout the country; Through the implementation of the system of multi-party cooperation and political consultation led by the * * * production party, the broad United front composed of all socialist workers, patriots who support socialism and patriots who support the reunification of the motherland, including compatriots in Taiwan Province Province, compatriots in Hong Kong and Macao and overseas Chinese, has been consolidated and expanded; Through the policy of "one country, two systems", the smooth return of Hong Kong and Macao has been realized, and the century-old humiliation has been cleared. In the past century, China has been able to move from chaos to reunification, which is a great cause with boundless merits. Without the organization, cohesion, guidance and unity played by the China * * * Production Party, it is unthinkable. The China * * * Production Party advocated and established an advanced and lofty value system, inherited, absorbed and promoted advanced Chinese and foreign cultures, changed the mental outlook of the people in China and promoted the development and progress of Chinese civilization. Over the past 80 years, the China * * * Production Party has not only influenced the historical process of China politically and organizationally, but also transformed Chinese civilization ideologically and culturally by gradually forming a scientific world outlook and values, which has had a far-reaching impact on the spiritual world of the Chinese nation. China's * * * production party accepted Marxism–Leninism from the west through comparison and identification, and gradually combined it with China's reality, making it China, realizing two historic leaps in thought and theory, and successively produced Mao Zedong Thought and Deng Xiaoping Theory. As the basic theory of the Party, it not only guides all the actions of the Party itself, but also spreads widely and deeply into the body of China society and people's thoughts, becoming the spiritual pillar of the Chinese nation. China * * * production party also absorbed many other achievements of foreign civilization, especially advanced science and technology, management experience and so on. Since the reform and opening up, cultural exchanges between China and foreign countries have become more extensive. Deng Xiaoping's thoughts of "looking at the world", "catching up with the times" and "three orientations" have pushed us to the world and broadened our horizons. The 80-year history has proved that to promote the continuous progress of the Chinese nation, we must adhere to the leadership of the * * * production party. The ruling position and leading position of the China * * production party are determined by the nature of the party's vanguard of the working class, formed in the test of long-term struggle, and the people's choice and historical necessity. The historical changes in China in the 20th century have proved that only the China Productivity Party can lead the people of China to win national independence, people's liberation and socialism, create the road of Socialism with Chinese characteristics, and realize national rejuvenation, national prosperity and people's happiness. In old China, no political party could lead the abyss of China and out of the dark. In contemporary China, no other force can replace the leadership and ruling position of China's * * * production party. Without the leadership of the Party, China would be in chaos. Therefore, upholding the Party's leadership is the key to China's development, stability and socialist modernization. Facing the new century, the party's leading position can only be adhered to, not weakened, not strengthened and not shaken. This is determined by objective reality, by the fundamental interests of the Chinese nation, and not by personal will.
