Dang Kou

In early 1938, the Japanese army invaded Shandong Peninsula. A box containing important military secrets of the Japanese army passed through Yidu County and was robbed by the righteous Gong Sunxian. Therefore, he was hunted by Japanese agents. Before his death, he entrusted the box to Yang Baoguo, the owner of the Yongxing Martial Arts Gym. Yang Baoguo, the owner of the Yongxing Martial Arts Gym, swore to defend the box to the death and was killed by the Japanese agents. Yang Erhu, who was hated by his country and family, vowed to avenge his father and protect his family and country. Inspired by his brother Yang Dalong, an underground party member, and progressive students Xia Ling, Gong Sunyu and others, he gradually realized that his personal resistance to Japan was weak and that only relying on the Communist Party could save China. Erhu inherited his father's legacy of resisting Japan and saving the country, and fought wits and courage with Osakaoka. They started a desperate battle for the box, and gradually uncovered the Japanese secret plan to develop highly toxic biological and chemical weapons. They finally defeated the Japanese conspiracy and successfully destroyed the Japanese biological and chemical weapons development base in Sheshan. Yang Erhu further strengthened his determination to defend his homeland and continued to grow on the road to resisting Japan and saving the nation. He gloriously joined the Communist Party of China and became a true revolutionary warrior.
