In 2001, he lost all his savings by fish farming, but he discovered in the Guangdong aquatic market: soft-shell turtle prices vary tenfold—cheap ones cost twenty yuan per jin, while the expensive ones are over 200 yuan per jin. After inquiring, he found out: the cheap ones are farmed in greenhouses, and the expensive ones are wild soft-shell turtles. He pondered: he had seen wild soft-shell turtles in his reservoir, so why not buy tens of thousands of fry and let them grow naturally? He spent two years flipping second-hand appliances and saved hundreds of thousands.
