In the auto parts city, the beef noodle restaurant run by Zhou Jianguo sticks to ingredient quality, pricing at 22 yuan due to rising costs. A newly opened restaurant across the street relies on low-price promotions to grab customers, introduces monthly passes, bribes factory management to monopolize the factory area's customer flow, and even uses inferior frozen meat and additives to make meals. In the end, the workers are poisoned, and the opposite noodle restaurant is investigated and dealt with. Zhou Jianguo sticks to his bottom line and is invited to provide meals, insisting on the principles of limited quantity, freshly cooked, accurate weighing and sufficient portions, which helps workers recover their physical strength and guards his original business aspiration.
