During the 1939 Battle of Fanchang, Zhu Zhen, a platoon leader of the New Fourth Army, led his unit in escorting journalist Lu Ying, who carried evidence of the Japanese army’s atrocities in Nanjing as well as their operational plans. Pursued and blocked by Japanese forces, the team suffered continuous casualties and endured life-and-death trials, including ambushes on snowy plains and fierce combat in mountain caves. In the end, Zhu Zhen sacrificed his life for the mission, while Lu Ying successfully delivered the evidence, aiding the New Fourth Army in securing victory and exposing the crimes of the Japanese military.
