You thought 35 yuan per jin was too expensive back then, but now nobody wants them even for free! Gu Chuan obtains official documents warning of an approaching typhoon in advance and offers to buy the villagers' crabs at 30% above market price, guaranteeing a buyer for their harvest. Instead, the entire village calls him unscrupulous and accuses him of taking advantage of their misfortune. When the typhoon hits, the embankments collapse, and millions of river crabs escape overnight, leaving the villagers drowning in debt. They come begging him to buy their remaining crabs, but he coldly replies, "Too late." In the end, the neighboring village grows prosperous under his leadership.
