On this day 66 years ago, on June 29, 1959 (May 24, 1959 in the lunar calendar), Mao Zedong Lushan talked about the lessons of the "Great Leap Forward". On June 29, 1959, Mao Zedong Lushan talked about the lessons of the "Great Leap Forward". The original purpose of the Lushan Conference held in 1959 was to summarize the experience and lessons since the "Great Leap Forward", correct the "left" impatient and aggressive tendency to advance, and improve the comprehensive balance. However, due to Peng Dehuai's letter in the later stage of the meeting, the meeting quickly turned against the right. Regarding the original purpose of the Lushan Conference, Mao Zedong's conversation with the directors of the coordination districts in Lushan on June 29, 1959 can be used as a powerful proof. Mao Zedong said: One of the important lessons of the "Great Leap Forward" is that the comprehensive balance is not done well, which is a fundamental problem in economic work. Only by doing a good job in the balance between agriculture itself, agriculture, forestry, animal husbandry, deputy and fish, the balance between various departments and links within the industry, and the balance between industry and agriculture, can the proportional relationship of the entire national economy be correctly handled. Mao Zedong also said that in the past, the order of arranging the national economy was heavy industry and light agriculture, but in the future, I am afraid it will be reversed. For the first time, it was proposed to arrange the national economic plan in the order of agriculture, light and heavy. Mao Zedong believed that Chen Yun's opinion in the past that "the market should be arranged first, and then the infrastructure should be arranged" was correct. To arrange the food, clothing, housing and transportation, this is a problem related to the stability of the five hundred million people. Mao Zedong also pointed out that there is some semi-anarchism in the current economic management system. " The four powers (human rights, financial rights, commercial rights, and industrial rights) "were released more in the past, but faster, causing confusion. Unified leadership and centralized power should be emphasized. Decentralized powers should be properly recovered. Comments: The lessons of the Great Leap Forward are too profound!
