King Huai of Chu was about to release Zhang Yi back to Qin, yet he feared that Zhang Yi would sabotage his plans and cause Chu to lose territory before Qin. Jin Shang said to King Huai, "Allow me to accompany Zhang Yi to Qin. If through diplomacy I can secure the land, then Your Majesty shall not lose it; if I cannot secure it, I shall request permission to put Zhang Yi to death." King Huai replied, "Very well." Thereupon Jin Shang journeyed to Qin together with Zhang Yi. Jin Shang then said to the King of Qin, "Permit me to sow discord between Your Majesty and Zhang Yi." The King of Qin answered, "Very well." Jin Shang then spoke to Zhang Yi, saying, "I have heard that in returning to Qin, you intend to exchange Chu's territory for Chu's crown prince. In my private reckoning, your land is insufficient to compensate for the crown prince of Chu, and moreover, your territory would surely be ceded in full. If you would heed my counsel, I shall see to it that a lady of Qin is wed to the King of Chu as his wife, and that the King of Chu sends his crown prince to Qin as a hostage. Thus shall the alliance between Qin and Chu be made firm, and your territory preserved." Zhang Yi, finding the argument sound, said to the King of Qin, "I request that a lady of Qin be wed to the King of Chu as his wife, and that the King of Chu send his crown prince to Qin as a hostage." The King of Qin replied, "Very well." So the King of Qin halted Zhang Yi's departure, and instead the crown prince of Chu came to Qin as a hostage. The King of Chu, seeing that Zhang Yi remained in Qin, dispatched an envoy to present the territory to Qin.
💡 商战启示录
This passage illustrates how the strategist Jin Shang, through dual-agent tactics, safeguarded Chu's interests amid the Qin-Chu power struggle while neutralizing the threat posed by Zhang Yi. In modern commercial warfare, this strategy can be translated into "information intermediation" and "interest restructuring." For instance, in corporate merger negotiations, when both parties reach an impasse due to information asymmetry, a third-party advisor (the equivalent of Jin Shang) can engage both buyer and seller simultaneously, leveraging their respective concerns—the seller's fear of asset depreciation, the buyer's worry of overpaying—to propose a "share swap + performance earn-out" structure, transforming adversarial negotiation into a collaborative framework that satisfies the buyer's need for control while securing the seller's exit returns. Jin Shang's "sowing discord" was in essence a redesign of the transactional architecture, leading both sides to believe the new proposal surpassed the original. In business practice, as in Alibaba's acquisition of NetEase Kaola, an intermediary may introduce cross-border logistics resources as a "hostage" to balance mutual trust and ultimately close the deal. The key insight: masters of commercial strategy do not confront head-on; rather, like Jin Shang, they alter the game's dynamics by forging new interest alignments—be it through alliance or hostage—turning the opponent's moves into one's own strategic placements, achieving victory without engaging in battle.
