From the Marco Polo Bridge Incident in 1937 to the victory of the Anti-Japanese War in 1945, it covered the entire cycle of the Anti-Japanese War in North China - from the early rapid advance of the Japanese army and the fall of North China, to the establishment of anti-Japanese base areas behind enemy lines and the launch of guerrilla warfare, to the Japanese army's "mopping up/clearing out/encroaching" base areas into the most difficult stalemate stage, and finally to local counterattacks and victory. It covers various forms of resistance such as mountain guerrilla warfare, breach warfare, mine warfare, tunnel warfare, and traffic breach warfare, and restores the true situation of the base area where supplies are scarce, equipment is backward, and the military and civilians are united, taking into account both historical reality and artistic creation.
