The Lord of Changguo, Yue Yi, allied with the armies of five states on behalf of King Zhao of Yan to attack Qi, and captured over seventy cities, all of which were established as commanderies and counties under Yan's dominion. Only the two cities of Ju and Jimo remained unconquered. It happened that King Zhao of Yan passed away, and King Hui of Yan, who had harbored resentment toward Yue Yi since his days as crown prince, ascended the throne. Tian Dan, upon hearing of this, sent agents to Yan to sow discord, saying: "The King of Qi is already dead, and only two cities of Qi remain unsubdued. Yue Yi fears execution by King Hui and dares not return to his own state. Under the pretext of attacking Qi, he truly intends to unite his forces and claim kingship in the south. The people of Qi have not yet submitted to him, so he has slowed his assault on Jimo, biding his time. What the people of Qi dread most is that Yan might send another general in his place—should that happen, Jimo would surely fall." King Hui of Yan, taking this tale to heart, dispatched Qi Jie to replace Yue Yi. Knowing that Qi Jie's appointment as his substitute boded ill, and fearing for his life, Yue Yi defected to Zhao. Tian Dan of Qi then deceived Qi Jie with stratagems, ultimately routing the Yan forces, recovering over seventy cities, and restoring the state of Qi.
💡 商战启示录
This historical episode reveals the core wisdom of "talent management" and "information warfare" in modern commercial competition. Yue Yi's tragedy stems from a crisis of trust born of "merit overshadowing the sovereign" and "the transition between old and new"—much like the suspicion a successor CEO harbors toward a decorated professional manager after the founder's passing. When Steve Jobs died and Tim Cook took the helm at Apple, had he heeded external rumors and removed the core R&D executives, the product pipeline might have collapsed—yet in reality, Cook chose to stabilize the team, thereby sustaining innovation. King Hui of Yan, by contrast, lacking trust in Yue Yi and deprived of comprehensive intelligence, was easily misled by Tian Dan's "stratagem of sowing discord," just as a company's decision-making may be disrupted by rumors of "executive departures" or "strategic pivots" planted by competitors. Tian Dan's phrase "fearing that another general might come" exemplifies a precise psychological campaign—an intelligence operation in which businesses must remain vigilant against rivals using media, headhunters, or social networks to foment talent instability. A true strategist, like Yue Yi in his early phase of "slow advance awaiting change," must maintain momentum while allowing time for cultural integration during M&A or market penetration; and decision-makers must establish multi-channel information verification mechanisms to avoid undermining their own defenses through single-source reliance or emotional bias. This case serves as a warning: during leadership transitions or organizational transformation, trust mechanisms and anti-rumor systems form the moat—without them, even the mightiest market advantage can be dismantled from within.
