In Shandong in 1942, Wang Qiang, a member of the railway guerrillas, was responsible for destroying the Japanese army's railway transportation lines and cooperating with counter-mopping up in the base area. He and his comrades planned to blow up the "Japanese Army Material Transport Bridge" - there were heavy Japanese troops stationed on the bridge. Wang Qiang disguised himself as a railway worker, sneaked into the bridge pier and installed explosives. During the operation, his comrades were discovered by the Japanese army. Wang Qiang was unfortunately injured while protecting his comrades.
