In ancient China during the Three Kingdoms era, the warlord Cao Cao receives an exotic gift: a massive elephant, a beast so enormous that no scale in the kingdom can measure its weight. Determined to know the creature's exact mass, Cao Cao commands his scholars and engineers to find a solution, but they hit a wall. Nobody can devise a method to weigh something so impossibly large. Then Cao Chong, the warlord's brilliant youngest son, steps forward with a deceptively simple idea. Rather than struggle against the elephant's size, he proposes working with it, turning an impossible problem into an elegant puzzle. What unfolds is a comedy of ingenuity that celebrates lateral thinking over brute force. The film balances humor with genuine cleverness as characters clash over their approaches, with Cao Chong's calm logic cutting through the chaos of frustrated adults. It's a lighthearted historical tale that finds comedy in human nature: our stubborn insistence on solving problems the hard way, and the refreshing moment when someone younger sees what we've all been missing.
