Lin Weidong runs a leather shoe factory in a remote location. For three years, he regularly ordered braised pork rice for his employees from the street vendor Zhao Daqiang at 30 yuan per serving. By chance, he discovered that Zhao Daqiang charged walk-in customers only 15 yuan per serving, with generous portions and a free drink. Zhao had made over a million yuan in profits over three years by exploiting the price difference on the factory's bulk meal orders. Lin Weidong immediately terminated their cooperation. He then met the honest and hardworking Chen couple, who insisted on using fresh, high-quality meat and charging transparent prices regardless of whether customers were new or regulars. Lin handed all the factory's meal orders to them. Furious at losing the lucrative contract, Zhao Daqiang joined forces with factory partner Zhao Dequan to take revenge, sabotaging the braising broth, bribing employees to add laxatives to the food, and spreading rumors to defame the couple.
