The Thought Reform Movement first began in September 1951, following a speech by
premier Zhou Enlai calling for intellectuals to reform their thought. The ''
People's Daily'' called for teachers and college staff to "arm oneself with the thought of Marxism–Leninism" and to "throw away the vulgar perspectives of individualism and liberalism, and the cultural thought of European-American
reactionary bourgeoisie". Intellectuals who studied overseas were forced to confess to their role as "implementers of the imperialist cultural invasion", while writers across the country were ordered to study Mao's lectures in the "
Talk at Yan'an Forum on Literature and Art" and engage in self-criticism. During the movement, many school curricula were restructured, with science and engineering adapting the Soviet models, while courses seen as "pseudo-bourgeois", such as sociology, political science, and economics, were abolished. The thought-reform program applied in universities, schools, special "revolutionary colleges", prisons, businesses, government offices, and peasant organisations. It brought significant personal upheaval to the individuals affected. == "New Socialist Man" ==
