Li Tao, a master of traditional Chinese pastries, is schemed against by his relatives and kicked out with nothing. Burdened with the responsibility of paying for his mother's medical treatment, he finds himself at the end of his rope. Staying true to his craftsman's principles, he relies on a jar of sourdough starter that has been cultivated for three years and his mastery of traditional techniques. Starting from a shabby stall in a vegetable market, he wins over the taste buds of the local community with handmade baozi made from quality ingredients. He uses his skills to expose unscrupulous merchants who cut corners, defeating flashy gimmicks backed by capital with the warmth and authenticity of everyday street life. He carries on the legacy of traditional Chinese pastry-making, rejects exorbitant offers from investors, and uses his own hardworking hands to turn ordinary baozi into a beloved symbol of the city's warmth and everyday life.
