抗战胜利后,东北地区成为国共两党争夺的首要目标。为了夺取东北,创造有利于我的战略态势,中共中央作出了“向南防御,向北发展”的战略决策和一系列的战略部署,指导我党我军先机进入东北创建根据地。在3年多的时间里,我军先后进行了四平保卫战、“三下江南”、“四保临江”等防 After the victory of the Anti-Japanese War, the northeast region became the primary goal of the two parties fighting for the Kuomintang and the Communist Party. In order to seize the northeast and create a favorable strategic situation for me, the CPC Central Committee has made strategic decisions and a series of strategic plans for “defensive southward development and northward development” and guided our party and our army to establish bases in the northeast. In more than three years, our army has successively conducted the Siping War of Independence, the “three under the south” and the “four protected Linjiang”
