On April 27, 1957, the Central Committee of the Communist Party of China issued the "Instructions on the Rectification Movement." It pointed out that in order to overcome the newly growing bureaucracy, sectarianism and subjectivism that are divorced from the masses and reality within the party in recent years, it is necessary to carry out a general and in-depth rectification movement throughout the party to improve the Marxist ideological level of the party., improve work style, and adapt to the needs of socialist transformation and construction. The "Directive" also points out that in handling contradictions among the people, we must follow the policy of "proceeding from the desire for unity, through criticism and self-criticism, and achieve a new unity on a new basis", and implement the principle of "saying everything you know and saying everything you say, and the speaker is innocent. Those who hear should be warned, if there is something to change, and if there is nothing to encourage them" to achieve the goal of "learning from past mistakes to avoid future ones, and curing illnesses and saving people."
