The King of Yan said to Su Dai, "I am eager to hear your strategy, yet I abhor excessive cunning. Now you speak of Qin—if Qin does not heed your counsel, what will you do?" Su Dai replied, "I have heard that loyalty and trustworthiness are the noble conduct of a scholar, while deceit and falsehood are the base behavior of a scholar. What I am about to say is neither deceitful nor false. I beg to go and persuade the King of Qin on Your Majesty's behalf, so that Qin will not send troops against Yan, and Yan may yet obtain precious treasures—this is my wish. If Qin does not comply, I am willing to let the blood from my neck stain the hem of Your Majesty's robe." The King of Yan said, "Well said." Su Dai then journeyed to Qin and addressed King Zhaoxiang of Qin, saying, "I have heard that an enlightened sovereign does not detest loyal words, and a wise ruler does not reject forthright remonstrance. Now, though the state of Yan is small, its aspirations are far-reaching, and its strength is sufficient to defend itself. If Your Majesty seeks to attack Yan, I fear the other feudal lords may harbor divergent intentions. It would be better to forge a bond of amity with Yan, making it a vassal in the east, to jointly resist the feudal lords. Thus, Qin would have no worries from the east, and the feudal lords would not dare to cast covetous eyes upon Qin." King Zhaoxiang of Qin said, "Well said." Thereupon he ceased military action and formed a bond of amity with Yan.

Su Dai's strategy stands as a classic paradigm of "win-win thinking" and "risk hedging" in modern business negotiation. Rather than directly petitioning the State of Qin to abandon its expansionist ambitions, he reframed the structure of interests, pointing out that a forceful assault on Yan would trigger the "systemic risk" of a united coalition of feudal lords—thereby transforming a "zero-sum game" into a "symbiotic alliance." This mirrors how today's enterprises, when facing competition from industry giants, refrain from head-on confrontation and instead propose "ecosystem cooperation" schemes—such as small and mid-sized tech companies lobbying industry leaders to jointly set standards against external disruptors, or regional brands forging alliances with national platforms, trading channels for security. Su Dai further underwrote his proposal with the extreme pledge of "neck blood staining one's robes," which in essence represents a prototype of the modern "bet-on agreement" in commerce: using personal credibility or core assets as performance guarantees to reduce the counterparty's cost of trust. And although the King of Yan harbored suspicions of "deceitfulness," he nonetheless authorized Su Dai—reflecting how leaders must weigh risk against opportunity, just as a CEO confronted with an external advisor's aggressive strategy must assess its feasibility rather than prejudge its motives. In the end, Su Dai achieved his objective without losing a single soldier or horse, delivering a cautionary lesson for modern commercial warfare: the most brilliant offense is to eliminate the necessity of offense, and the most impregnable moat is to make your rival believe that cooperation with you is more advantageous than confrontation.
