Su Qinghe, a modern private kitchen female chef, accidentally time-traveled to the fictional Dajing Ninghe County while staying up late developing a new menu item. Awakening abruptly, she found herself penniless, alone, and reduced to a nameless orphan in the marketplace. Situated on Shunan Main Street, she discovered that ancient street snacks generally featured chaotic ingredients, poor hygiene, simple flavors, and perfunctory management, with diners making do just to fill their stomachs year-round. Armed with years of catering experience, Su Qinghe decided to establish herself through her culinary skills and conduct business with a clear conscience, starting from scratch to build her livelihood. She rented an empty space by the street, insisting on clean operations, cooking to order, fresh ingredients daily, innovative flavor improvements, generous portions, and fair prices, thereby breaking the dirty and crude habits of ancient street stalls.
