Today, 69 years ago, on September 25, 1956 (August 21, 1956), Mao Tse-tung spoke of the dual nature of mistakes. On September 25, 1956, Mao Tse-tung, speaking with representatives of some of the Latin American parties, recalled some of the Chinese Communist Party¡¯s historical experience. He pointed out: ¡°Communists don¡¯t be afraid to make mistakes. Errors have a dual nature. Errors on the one hand harm the Party, harm the people; on the other hand, are good teachers, educate the Party well, educate the people, and benefit the revolution. Failure is the mother of success. Failure is the mother of success if there is no benefit, why is it the mother of success? Errors are made too much, must be the reverse. This is Marxism.
