Lu Yuan has spent three years helping his village sell peaches, paying out of his own pocket to build a cold-storage facility and find sales channels. This year, the market is poor, so he offers to buy peaches at 2.5 yuan per jin. But the villagers believe outsiders who claim they can sell them for 3.8 yuan, accuse him of being unscrupulous, and seize the cold-storage keys. In the end, buyers only accept Lu Yuan's quality standards. The peaches are mixed together and turn soft, while the cold-storage facility deteriorates from improper use. Their promised high prices collapse into the price of rotten peaches. The villagers surround Lu Yuan's door and demand compensation. He produces the evidence and lays down the rules: Want to sell peaches? Follow the standards first.
