The state of Qin attacked Zhao, and the King of Zhao appointed Zhao Kuo to replace Lian Po as general. Lin Xiangru said, "Your Majesty employs him because of his reputation, but this is like gluing the tuning pegs of a zither before plucking the strings—the tones can never change. Zhao Kuo can only recite the military texts his father left behind; he knows nothing of adapting to circumstances." The King of Zhao paid no heed and appointed Zhao Kuo nonetheless.
From youth, Zhao Kuo had studied the art of war and discoursed on military matters, believing no one under heaven could rival him. He once debated strategy with his father, Zhao She, who could not refute him, yet never praised him. Zhao Kuo's mother asked Zhao She why this was so, and he replied, "War is a matter of life and death, yet Zhao Kuo speaks of it with reckless ease. If Zhao never employs him as general, so be it; but if he is employed, the one who will bring ruin upon our army is none other than he."
When Zhao Kuo was about to set out on campaign, his mother submitted a memorial to the King of Zhao, saying, "Zhao Kuo cannot serve as general." The King asked, "Why?" She answered, "In former days, I served his father. When his father was general, he personally offered food to more than ten guests and befriended over a hundred companions. Whatever the King and the royal clan bestowed upon him, he distributed entirely among his officers and men. On the day he received his command, he never once asked after household affairs. Now Zhao Kuo, the moment he becomes general, sits facing east to receive the homage of his subordinates, and no officer dares lift his eyes to him. The gold and silks Your Majesty bestows, he hoards away in his own home, and daily he scans the markets for cheap estates and fields to purchase. Does Your Majesty think he resembles his father? Father and son are of wholly different minds. I beg that Your Majesty not send him forth." The King said, "Leave this matter alone; my decision is made." Zhao Kuo's mother then said, "If Your Majesty ultimately sends him, and he proves unequal to the task, may I be spared from punishment by association?" The King consented.
After Zhao Kuo replaced Lian Po, he overturned every military regulation and replaced the officers. When the Qin general Bai Qi learned of this, he dispatched elite troops in a feigned retreat, then cut off the Zhao army's supply lines, splitting their forces in two and sowing discord among the soldiers. After more than forty days, the army was starving. Zhao Kuo personally led his finest warriors in a desperate sortie, and the Qin forces struck him down with arrows. The Zhao army suffered a catastrophic defeat—several hundred thousand soldiers surrendered to Qin, and the Qin forces buried them all alive. In total, Zhao lost four hundred and fifty thousand men.
The following year, the Qin army besieged the capital of Handan. For over a year, Zhao teetered on the brink of annihilation, and only through the rescue of Chu and Wei was the siege finally lifted. Because Zhao Kuo's mother had spoken beforehand, the King of Zhao ultimately spared her life.
💡 商战启示录
Zhao Kuo's failure was, at its core, a mismatch between "armchair strategy" and "battlefield experience." In the arena of commerce, many enterprises place blind faith in elite MBA credentials, star managers, or glittering résumés, while overlooking whether these individuals possess the adaptability required for frontline combat. For instance, a certain internet giant once recruited a senior executive from an international consulting firm to serve as COO at a handsome salary. This individual was well-versed in theoretical models, yet lacked any intuitive grasp of the channel ecosystem and price-war rhythms of the domestic lower-tier markets. Upon assuming office, he transplanted Western management frameworks wholesale and forcibly imposed standardized processes, leading to a mass exodus of regional distributors, a steady erosion of market share by competitors, and his eventual quiet departure. The parallel with Zhao Kuo's "altering all established rules and reshuffling military command" is unmistakable.
By contrast, Lian Po understood the protracted warfare of "fortifying positions to exhaust the enemy," which corresponds in business to cost control and supply-chain resilience. Zhao Kuo's "aggressive offense," meanwhile, resembles the reckless cash-burning expansion that ignores cash-flow security. Bai Qi's tactic of "cutting off supply lines" finds its commercial metaphor in severing an opponent's capital chain or access to core resources—as when a new-energy vehicle maker locked up upstream lithium mines, constraining rivals' production capacity.
A true business leader should be like Zhao She—able to stand on the front lines while also empowering others, never remaining aloof in an ivory tower. Zhao Kuo's mother, seeing clearly from the outside, reminds corporate decision-makers to institute hiring mechanisms that guard against the "halo effect," selecting generals by battlefield data rather than empty reputations. What you gain from books is ultimately shallow; true understanding demands hands-on practice. This ancient maxim, in the VUCA era of business competition, still rings with thunderous clarity.
