On this day, 69 years ago, March 6, 1956 (January 24, 1956 in the lunar calendar), an enlarged meeting of the Central Military Commission was held. On March 6, 1956, an enlarged meeting of the Central Military Commission was held. The main topics of the meeting were the strategic principles for defending the motherland and national defense construction issues. Peng Dehuai delivered a report on "Strategic Guidelines for Defending the Motherland and National Defense Construction Issues"; Ye Jianying delivered a report on "Several Issues on Military Training in 1956"; Huang Kecheng delivered a report on "Issues on Rectifying the Organization and Improving Leadership Methods"; Tan Zheng delivered a summary report on "On the Work of Eliminating Counterrevolutionaries in the Army"; Song Renqiong delivered a report on "Overcoming Conservatism in Cadre Work and Comprehensive Planning Issues for Cadre Work". The meeting determined the strategic policy of active defense: before the outbreak of war, continuously strengthen China's military strength, continue to expand international united front activities, and stop or delay the outbreak of war militarily and politically. When imperialism launches a war of aggression against China regardless of the consequences, the People's Liberation Army must be able to immediately provide a powerful counterattack, stop the enemy in predetermined fortified areas in the early stage of the war, stabilize the front line, cover the whole country from peacetime to wartime, and then gradually shift from strategic defense to strategic counterattack. The meeting also made provisions on this and put forward requirements for national defense construction. The meeting decided to reduce the current number of personnel in the entire army by one-third.
