The state of Qin attacked Zhao, and the King of Zhao sent Zhao Kuo to replace Lian Po as the general. Lin Xiangru admonished, saying: "Your Majesty appoints Zhao Kuo merely on the strength of his reputation—this is like gluing the tuning pegs of a zither before plucking it; the notes cannot be modulated. Zhao Kuo can only recite the military manuals left by his father; he knows nothing of adapting to circumstances." The King of Zhao paid no heed and insisted on employing Zhao Kuo.
From childhood, Zhao Kuo had studied the art of war and discoursed on military affairs, believing himself unmatched under heaven. He had once debated strategy with his father, Zhao She, who could not confound him, yet offered him no praise. Zhao Kuo's mother asked Zhao She why this was so, and Zhao She replied: "War is a matter of life and death, yet Zhao Kuo speaks of it with careless ease. If Zhao does not employ Zhao Kuo as general, so be it; but if he must be employed, the one who will bring ruin upon the Zhao army is none other than he."
When Zhao Kuo was about to set forth on campaign, his mother submitted a letter to the King of Zhao, saying: "Zhao Kuo is unfit to serve as general." The King asked: "Why?" She answered: "When I served his father in former days, he, as a great general, personally offered food and drink to dozens of guests and befriended hundreds of companions; the gifts bestowed by Your Majesty and the royal clan he distributed entirely among his officers and retainers; and from the day he received his command, he concerned himself no more with household affairs. Now Zhao Kuo, the moment he becomes general, sits facing east to receive homage, and no officer dares lift his eyes to him; the gold, silver, silks, and fabrics bestowed by Your Majesty he carries home and stores away, and daily he seeks out cheap lands and dwellings to purchase. Does Your Majesty think him like his father? Father and son are of different hearts—I beg that Your Majesty not send him forth." The King said: "Trouble yourself no further; my mind is made up." Zhao Kuo's mother then said: "Since Your Majesty has resolved to send him, if he proves unworthy of his charge, I pray that I may not be implicated." The King consented.
After Zhao Kuo replaced Lian Po, he altered every established regulation and dismissed a great number of officers. When the great Qin general Bai Qi learned of this, he dispatched elite troops in a feigned retreat, secretly cutting off the Zhao army's supply routes, splitting the Zhao forces into two, and the soldiers' morale dissolved. After more than forty days, the Zhao army's provisions were exhausted, and Zhao Kuo personally led his finest troops in a desperate breakout, only to be struck down by a hail of arrows from the Qin forces. The Zhao army suffered a catastrophic defeat; several hundred thousand soldiers surrendered to Qin and were buried alive by the victors. In all, Zhao lost four hundred and fifty thousand men.
💡 商战启示录
Zhao Kuo's defeat stems from "armchair strategy"—possessing theory alone without practical combat experience, compounded by stubborn self-will and disregard for his subordinates. In modern business, many "star managers" or "elite MBA graduates" parachuted into enterprises indiscriminately apply textbook models, ignoring industry realities and organizational culture, ultimately leading to strategic failure. For instance, a major internet company once recruited a multinational executive at great expense to pursue aggressive expansion strategies without considering local market maturity; after burning through subsidies, user retention remained extremely low, and the project collapsed. Conversely, Huawei's Ren Zhengfei emphasizes "letting those who hear the guns call for fire," respecting frontline experience and avoiding blind application of theory, thereby ensuring steady growth. Zhao Kuo's defeat also warns that leaders must possess the capacity for "adaptive transformation"—dynamically adjusting strategies in response to circumstances. Kodak, clinging to its film business and refusing digital transformation, was ultimately eliminated by the market; Nokia, despite early development of touchscreen technology, lost its opportunity through conservatism. Business warfare mirrors military warfare—markets shift in an instant. Only by integrating theory, practice, and flexible adaptation, while establishing effective feedback mechanisms that heed grassroots voices, can one avoid repeating Zhao Kuo's tragic mistake.
