Trivia, insights & behind the scenes
The New Fourth Army was a real Communist force during WWII, making this rare prestige TV about their intelligence operations rather than conventional battles.
The title 'Jue Sheng' (决胜) translates to 'Decisive Victory'—ironic given the series focuses on small, precarious gambits rather than triumphalism.
