Xu Shiming is a grape buyer in Qingteng Village who has guaranteed a market for the villagers' harvest for years, backed by cold-chain logistics, grading standards, and direct supermarket supply channels. However, after villagers Liu Jinlan, Zhao Xiaobo, and others believe screenshots of inflated prices circulating online, they accuse him of buying grapes at unfairly low prices and making dirty money. They lead a mob to block his refrigerated trucks, destroy supermarket-bound goods, and forcibly take ungraded grapes to the market to challenge him, hoping to pressure Xu Shiming into raising his prices. But Xu Shiming has already seen through their scheme. He immediately issues refunds and stops purchasing from them, turning instead to qualified grapes from neighboring Fenghuang Village. By letting market rules take their course, he makes the villagers suffer the consequences of trying to sell ungraded grapes at premium prices.
