Thought reform in the People's Republic of China (Chinese: 思想改造; pinyin: sīxiǎng gǎizào, also known as "ideological remolding" or "ideological reform") was a campaign of the Communist Party of China to reform the thinking of Chinese citizens into accepting Marxism-Leninism and Mao Zedong Thought (Maoism) from 1951–1952. Techniques employed included indoctrination, "struggle sessions," propaganda, criticism and self-criticism, and a variety of other techniques.
The Chinese term sīxiǎng gǎizào (思想改造, lit. "thought reform") "ideological remolding" compounds the words sīxiǎng () "thought; thinking; idea; ideology" and gǎizào "transform; reform; remold; remake; correct".
The related term sīxiǎng gōngzuò (思想工作, lit. "thought work"; also translated as thought-work or thoughtwork) "ideological education", with gōngzuò () "work; job". In modern CCP usage, sīxiǎng gōngzuò "thought work" is a more inconspicuous term for sīxiǎng gǎizào "thought reform".
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 "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 speech "Talk at Yan'an Forum on Literature and Arts" 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-bourgeoisie" such as sociology, political science, and economics were abolished.
