The October Revolution ushered in a new epoch in human history. Since primitive society, the evolution of social morphology and change of social system involved the replacement of one exploiting society by another with a new ruling exploiting class. The October Revolution put an end to the system of human exploitation and oppression and overthrew the rule by the exploiting class. A society without exploitation and oppression, and a social system with the people as the masters of the country, were established. People's democracy became a reality. From then on, socialism entered an historical stage as a brand new social morphology and social system, greatly influencing the developmental direction of human society. Under the influence of the October Revolution, socialism became an important choice for many countries to gain national independence, liberation and development. Countries embarked on the socialist road one by one; one-third of world's population once lived under the socialist system, which reinforced the socialist cause and broke the monopoly of capitalism. Socialism became the backbone for safeguarding world peace and development. The victory of the October Revolution, especially Lenin's ideology regarding national liberation of colonial and semi-colonial countries, greatly pushed the awakening of people oppressed by imperialism and colonialism, and the rise of national liberation forces in colonial and semi-colonial countries. It accelerated the worldwide disintegration of the colonial system created by imperialism, and altered the composition of international power and the world structure. Because of the increasingly manifested superiority of the world socialist movement and the socialist system, many capitalist countries had to make constant adjustments in their ruling strategy and seek improvement through the introduction of some measures from the socialist system so as to mitigate the increasingly sharp basic contradictions in the capitalist system.

The October Revolution brought Marxism-Leninism to China. After the First Opium War, China was gradually reduced to a semi-colonial and semi-feudal society and the Chinese nation was plunged into deep suffering. Countless patriots and righteous people in China tested various doctrines and thoughts in order to find the right way to save the country and its people, but all their efforts ended in vain. The success of the October Revolution tremendously shocked and inspired the progressives in China, who were wandering at their wits' end in the dark. The October Revolution ignited a new hope for realizing national independence and people's liberation. Since then, by using the ideals, viewpoints and methods of Marxism-Leninism, they gradually recognized the development trend of the human society, saw clearly the reality that the imperialists were carving up the world and oppressing China, and therefore got a clear understanding of the nature of the Chinese society and the goal of the Chinese revolution. In the end, they finally sought out the fundamental solution to saving the nation in peril – the path of socialism which was opened up by the October Revolution. Comrade Mao Zedong deeply pointed out: "The salvoes of the October Revolution brought us Marxism-Leninism. The October Revolution helped progressives in China, as throughout the world, to adopt the proletarian world outlook as the instrument for studying a nation's destiny and considering anew their own problems. Follow the path of the Russians -- that was their conclusion." Those Chinese progressives, during the process of combining Marxism-Leninism with Chinese workers' movement, established the Communist Party of China (CPC). As a result, the Chinese revolution has since then taken on an entirely new look. Under the strong leadership of the CPC, the Chinese nation indestructibly gathered and united from the state of loose sand, holding steadfastly its own future and destiny. Under the leadership of the CPC, the Chinese people fought heroically for 28 years and secured the victory in the new-democratic revolution, gaining national independence and liberation of the people. Comrade Mao Zedong said: "The people's revolution led by the Communist Party of China has always been a part of the world socialist revolution of the proletariat initiated by the October Revolution." After the founding of the New China, the CPC led the Chinese people to complete the socialist revolution, establish the system of socialism, advance socialist construction, conduct reform and opening up, establish and develop socialism with Chinese characteristics, and obtain an achievement that attracts worldwide attention.
