82 years ago today, on July 30, 1943 (June 29, 1943 in the lunar calendar), Mao Zedong issued instructions on work behind enemy lines. On July 30, 1943, Mao Zedong issued instructions to the Central Bureaus, Central Sub-bureaus, and District Party Committees on the principles, policies, and tasks of work behind enemy lines. It was pointed out that Jiang Hu's plan to attack the border areas was exposed by me in time. Seeing that I was prepared, I was forced to temporarily stop it. There is hope for one year of peace, but my military defense preparations must not be relaxed. As for the work principles and policies in the liberated areas behind the enemy lines, on the basis of the original six policies, we should add the struggle against the enemy (anti-sweeping and anti-encroachment), and add class education to become eight policies. The order is: struggle against the enemy; rectify the three winds; streamline the army; unify leadership; support the government and love the people; develop production; review cadres and class education. The common and frequent tasks among the masses are war, production, and education. Class education is class education that is unified and isolated. The name of class education is not mentioned externally.
