An in-depth analysis of the classic masterpiece of domestically produced alternative espionage wars, subverting the hard-core narrative of traditional espionage wars.

The humorous and down-to-earth narrative style, the unique spy war perspective on the economic front and the vivid and three-dimensional character portraits are combined with the atmosphere of the market in addition to the tense game of power to unlock the unique charm of the spy war theme.
