The rectification movement refers to a series of ideological education and rectification work carried out by China in order to strengthen the Party's ideological and organizational construction, improve the Party's Marxist level and overcome the non-proletarian ideology existing in the Party during the War of Resistance against Japanese Aggression period and the War of Liberation.

The main contents of the rectification movement include: opposing subjectivism to rectify the style of study, opposing sectarianism to rectify the style of work, and opposing stereotyped Party writing to rectify the style of writing. The rectification movement adopted the policy of "taking history as a mirror, curing diseases and saving lives", and achieved two goals of clarifying thoughts and uniting comrades through criticism and self-criticism.

The rectification movement is the first large-scale rectification movement in the history of China, which is of great significance for strengthening Party building and promoting the development of the China revolution.
