Introduction to the pre-war hall: The pre-war hall uses a variety of modern display methods such as multimedia and scene reproduction, as well as rich and detailed physical objects and photos, to show the audience the strength of the enemy and our forces before the Laiwu Battle in 1947. The deployment and pre-war situation vividly demonstrate the strategic shift of our army in order to encircle and annihilate the Li Xianzhou Group, cleverly set up suspicious troops, escape from the golden cicada, abandon Linyi, mobilize troops on a large scale, and "save the south for the north".
