After Su Qin's death, his younger brother Su Dai sought to carry on his legacy. He journeyed north to have an audience with King Kuai of Yan, saying: "I am but a humble man from the Eastern Zhou, yet I have privately heard of Your Majesty's lofty virtue. I wish to follow you and beg to serve as your minister. I have heard that an enlightened sovereign takes no pleasure in hearing ill of others, but delights in hearing what is good; he cares not for hearing of others' faults, but rejoices in hearing of their merits. Now, if Your Majesty desires to continue the enterprise of Su Qin, I am willing to devote my life to your service." The King of Yan replied, "I would entrust the affairs of my state to you." Su Dai answered, "I have heard that a filial son does not flatter his parents, and a loyal minister does not fawn upon his sovereign. Though I am but of modest ability, I wish to offer my sincere loyalty and dare not deceive Your Majesty with honeyed words. Su Qin, with the sharpness of his tongue, united the six states against Qin—yet he perished and his stratagems failed. Why? Because his words were too pleasing and his credibility insufficient. Now I beg to speak plainly, without empty rhetoric. If Your Majesty wishes to strengthen the state, you must first secure the foundation at home, and then observe the shifting tides abroad. Qi and Zhao are both formidable foes; they must not be rashly provoked. Rather, you should forge bonds with Han and Wei, draw close to Chu, and thereby hold Qi and Zhao in check. I request permission to organize a Vertical Alliance on your behalf, uniting the feudal lords against Qin. Then Yan may find peace, and Your Majesty's hegemony shall be achieved." The King of Yan said, "Well spoken." Thereupon he furnished Su Dai with chariots and horses, and sent him forth to unite the feudal lords. Su Dai then went east to have an audience with King Xuan of Qi, expounding the benefits of the Vertical Alliance. The King of Qi was delighted and gave his consent. He then journeyed west to persuade the three states of Wei, Han, and Chu, and all heeded his counsel. Thus the six states formed a bond of mutual amity, standing together against Qin. And the fame of Su Dai came to be second only to that of Su Qin himself.

Su Dai carried on his brother's legacy, yet not through mere replication—he drew instead from Su Qin's lesson that "sweet words breed thin trust," and turned to emphasize that "true words need no ornament." This mirrors the modern business reality: when a founder passes, the successor cannot blindly adhere to old strategies but must recalibrate based on market feedback. Su Dai first fortified the foundation within, then surveyed the shifting tides without—just as an enterprise should first consolidate internal management and cash flow, then analyze the external competitive landscape. He steered clear of the mighty states of Qi and Zhao, choosing instead to ally with Han, Wei, and Chu—a "blue ocean strategy" of not confronting giants head-on, but seeking complementary partners to build an ecosystem of alliance. Consider Huawei in its early days: rather than clashing with Cisco in Western markets, it delved deep into Africa and Southeast Asia, partnering with local operators to grow steadily. Su Dai's insistence that "a loyal minister flatters not his lord" serves as a reminder to business advisors and professional managers alike: one must not report only good news while concealing the bad, but speak truth grounded in data. Consulting firms like McKinsey, if they merely pander to clients, will ultimately forfeit trust. Su Dai's success in uniting the six states lay in his precise identification of each party's interests and his design of win-win solutions—much like modern platform enterprises such as Apple's App Store, which coordinate developers and users to generate multilateral network effects. In sum, Su Dai's strategy teaches us: succession demands innovation, alliances demand pragmatism, and only by speaking the truth can one earn lasting trust.
