He runs a fast-food cart outside a hospital, selling two meat dishes and one vegetable dish for 22 yuan. He would rather throw away an entire pot of braised pork than serve it the next day. On the day a 12-yuan meal shop opens across the street, all his customers disappear overnight. An internet celebrity livestreams to call him a heartless profiteer, a nursing-care agency threatens to cut off his business, and even his own nephew switches sides to work for the competitor. Nobody knows that ten years ago, this stubborn vendor missed his father's final moments because of an 8-yuan boxed meal. When five postoperative patients are rushed into the emergency room at the same time, the box of meat frozen for three years and the pot of reheated leftovers can no longer remain hidden. Rules must not be broken, and hearts must not grow cold.
