The story takes place in Anqiu City, a small and medium-sized town in Hebei Province, an anti-Japanese base area behind the enemy in 1943. At this time, our army's forces continued to grow and develop, and several surrounding counties and cities were liberated. The Japanese and puppets in Anqiu City were all panicked and thought of retreating. Cai Shuigen (played by Shi Xiaopeng), a big guy who runs a donkey meat restaurant "Dingxianglou", was quite appreciated by the Japanese puppets, and he was actually an underground Communist Party member who played the enemy in the palm of his hand. Under the leadership of Cai Shuigen, several Communist Party members launched a fearless underground anti-Japanese activity. The 28-episode sitcom "Underground Traffic Station" launched by Yingshi Company has become the first sitcom in China to reflect the theme of the Anti-Japanese War with its unique form and brand-new perspective after two years of careful planning. This drama adheres to the consistent style of Yingshi comedy, which makes the audience laugh while being influenced by revolutionary optimism and revolutionary heroism.
