During the Yuanyou period of the Northern Song Dynasty, Su Wanqing, a female chef with excellent skills, lived in Zhiwei Restaurant in Qiantang Lane. She guarded the stove alone and used the original flavors of ingredients to cook human fireworks. A bowl of Yangchun noodles and a piece of sweet-scented osmanthus and lotus root were both unique in Qiantang. In the food tasting competition, she defeated her opponents who were piling up delicacies with her original intention, and won the title of "Qiantang Food Sage". She also formed an indissoluble bond with the gentle scholar Qin Shaoyou. She originally wanted to stay in the small restaurant and live a stable life, but a secret letter from the Su family in Jiangnan revealed her life experience as a famous chef, which also attracted the covetousness of powerful people and the conspiracy of her peers. On the one hand, there is the stability of the fireworks in the market, and on the other hand, the mission of family inheritance. Su Wanqing stands up with a kitchen knife, using Song food as a blade, staying true to his original intention amidst the storm, and cooking a food legend belonging to the Song Dynasty.
