ABSTRACT
Owing to long years of oppression by the three big mountains–imperialism, feudalism and bureaucrat-capitalism –in old China, the productive forces developed at a very slow pace, and science and technology lagged far behind some countries. The history of science and technology shows that the creations and inventions of the world's laboring people in these fields cannot remain a monopoly of one nation for long but inevitably will sooner or later spread to all nations. The counterrevolutionary double-dealing tricks of the "gang of four" were similar to those of the bandit gang of Trotskyites. Lenin pointed out after the October Revolution the importance of obtaining as quickly as possible from the capitalist countries the means of production, such as locomotives, machinery, and electrical equipment.
