1June, 938, the battle of Wuhan broke out, and the anti-Japanese war situation was critical. Xie Gengyang, a military spy, took the initiative to "steal" Qingfan Meng, a spy of the Communist Party of China who had been secretly detained for a long time, shot him by the river, dumped his body in the river and drifted downstream to the Japanese position. Qingfan Meng, with Xie Gengyang's forged false information, convinced the Japanese that the Soviet army would send troops to the northeast, and the pace of attacking Wuhan was forced to slow down. Due to the hasty preparation, Xie Gengyang's plan went wrong, and Japanese agent Sato firmly believed that this was a conspiracy of China people. He personally went to Wuhan to verify the authenticity of the information. Qingfan Meng, who survived, learned from the Japanese torture that this plan would do harm to the Communist Party of China (CPC). He risked his life to escape from the Japanese camp and returned to Wuhan to stop it. The "Lie Plan" was submitted to the Kuomintang and communist party. In order to resist the Japanese war in Wuhan, the Kuomintang and the Communist Party decided to complete the "lie plan" hand in hand. In order to make up for the defects in the plan, Ma Xiaoyou, a female announcer of the Eighth Route Army, was arranged to pretend to be husband and wife with Qingfan Meng, and they were tested by the Japanese army. The intelligence elites of the Kuomintang and the Communist Party, together with Japan's most elite agents, waged a struggle in Wuhan around this lie plan.
