Introduction to the prologue hall: In the center of the prologue hall is a bronze statue "Toward Victory", which shows the leadership style of the five secretaries of the Central Committee of the Communist Party of China, Mao Zedong, Liu Shaoqi, Zhu De, Zhou Enlai and Ren Bishi. On the wall, there are embossed reliefs in Chairman Mao Zedong's handwriting on the operational policy of the Ping-Tianjin Campaign. The huge mural "Victory Symphonic Poem" surrounding it reflects the grand scenes of the soldiers and civilians in Northeast and North China fighting bravely and winning the battle.
