83 years ago today, on December 30, 1942 (November 23, 1942 in the lunar calendar), the Communist Party of China launched a large-scale production movement in northern Shaanxi.

At the end of December 1942, the Central Committee of the Communist Party of China put forward the policy of "developing the economy and ensuring supply", calling on the military and people in the base areas to be self-reliant, overcome difficulties, and carry out large-scale production movements. Since 1941, due to the frenzied offensive and brutal "sweep" of the Japanese army, the military siege and economic blockade of the Kuomintang, and the invasion of natural disasters, the finance and economy of the anti-Japanese base areas of the Communist Party of China have suffered extremely serious difficulties. The Central Committee of the Communist Party of China then formulated a series of specific policies for the large-scale production movement: in all production undertakings, the policy of giving priority to agriculture and the comprehensive development of agriculture, animal husbandry, industry, handicrafts, transportation and commerce; in public-private relations, the policy of "taking into account both public and private" and "military and civilian"; in the relationship between the top and the bottom, the policy of unified leadership and decentralized management; in the relationship between production and consumption, the policy of hard production and strict economy; in the form of organization, the policy of cooperation and mutual assistance, production competitions, and rewards for labor heroes. To promote the development of the large-scale production movement, leaders such as Mao Zedong and Zhu De also personally participated in productive labor. Inspired by slogans such as "Do It Yourself" and "Plenty of Food and Clothes", the army and the people in the base areas quickly launched a large-scale production movement dominated by agriculture. The anti-Japanese democratic government established a number of self-sufficient industries; the army developed agriculture and some industries and commerce with the goal of self-reliance; government organs and school personnel also developed self-sufficiency economy; farmers were widely organized to develop agricultural production. Through this movement, the Communist Party of China tried to overcome serious material difficulties in the areas under its jurisdiction and lay a material foundation for persevering in the Anti-Japanese War and striving for final victory.
