On May 27, 1949, Shanghai, the largest city in China, was liberated. Just as the people were excited and ready to celebrate their victory, a large number of counter-revolutionary spies lurking in Shanghai launched crazy sabotage activities under the leadership of the Military Commission's Liberation Society. They used speculators to speculate in silver dollars in an attempt to destroy the emerging RMB.In just one month, the Shanghai market was in chaos, prices soared, and people lived in dire straits.In order to smash the enemy's conspiracy, stabilize the market, and completely eliminate the power of the Guangfu Society, our army's reconnaissance hero, Yàn Shuangying, was ordered to disguise the Green Gang hooligan and invade the Guangfu Society.
