The October Revolution was the first successful socialist revolution in human history. It established the first socialist country led by the proletariat, opened up a new era for human beings to explore the socialist road, spread Marxism-Leninism to the whole world, and greatly shocked the capitalist world. The October Revolution declared to the whole world that a brand-new social system has changed from an ideal to a reality. For the first time in human history, the unequal society of exploitation and oppression has been eliminated, and it is the first time to try to build a beautiful society of fairness, justice and common prosperity. The October Revolution dealt a heavy blow to imperialist rule and greatly inspired the international proletarian revolutionary movement and the liberation movement of the oppressed people in colonies and semi-colonies. It changed the development direction of Russian history, transformed Russia in a socialist way, and had a great impact on the development of the whole human society. Mao Zedong wrote a passage in 1949: "The October Revolution brought us Marxism–Leninism with artillery. The October Revolution helped the advanced elements in the world and China, and regarded the proletarian world outlook as a tool to observe the destiny of the country and reconsider their own problems! ! !
