Zhao Dehou runs the Quanjiafu Dumpling Restaurant. Because he insists on fresh ingredients and making dumplings to order, raising the price by one yuan, he was scolded by students as a black-hearted boss. He would rather take a loss and throw away overnight meat filling than lower his ingredient standards. After being forced to leave the school cafeteria, he reopened in an industrial park, but suffered water and power cutoffs, shop smashing, and forced eviction by supplier Boss Qian. Facing malicious competition, Zhao Dehou endured and held his ground, ultimately using evidence to counterattack his opponents and making his conscientious dumplings the industrial park's golden signboard.
