97 years ago today, on November 11, 1928 (September 30, 1928 in the lunar calendar), the Communist Party of China demanded that the whole party correct its wrong ideas. On November 11, 1928, the Central Committee of the Communist Party of China issued the "Letter to All Comrades of the Central Executive Committee of the Communist Party of China", which once again clarified to the whole party the main content of the political line of the "Sixth National Congress" and the party's current general tasks and strategic guidelines. It is emphatically required that party organizations at all levels correct eight incorrect concepts such as paying attention only to legitimate movements and peaceful development, despising guerrilla warfare, ignoring the revolutionary role of the peasants, covering everything with peasant consciousness, giving up urban work, focusing on the countryside, giving up open movements, and fantasizing that a revolutionary upsurge is At the same time, it pointed out the harm to the party caused by the extreme democratization of the concept of internal party organization, the substitution of attacking individuals for criticism of opportunism, the struggle for personal morale, the establishment of small internal party organizations, the transformation of anti-opportunism into anti-intellectuals, the suspicion of the line of reforming the party, and the formalism of introducing a few workers as a method of reforming the party. Call on the whole party to overcome "left" and right mistakes such as opportunism and blind activism, strengthen party building, expand the party's political influence, win over and organize the masses, and promote the upsurge of the revolution.
