In Linjiang in the late autumn of 1944, the city's material franchise belonged to the Logistics Department of the Super High School. Shen Wanjin was the only black gold trader in Linjiang, holding the black market franchise of grain, medicine, cloth, tobacco and alcohol, and the gray income of the Japanese and puppet high-level officials.
At the same time, as a third-line spy for the military command, underground party, and Japanese and puppet agencies, Lu Wanjin and his comrades went through hardships and completed difficult tasks one after another, and ultimately witnessed the demise of Japan and the founding of New China.
