On Bianjing West Street, the smoke and smoke of the Lin family's health-preserving snack stall hides the survival wisdom of Lin Wanzhao, a time-traveling girl. A bowl of Poria wontons, she "picked up" the down-and-out scholar Shen Yan. Seeing that he stayed up late studying hard and looked haggard, she gave him a yam cake as a gift: "Sir, you must first nourish your spleen and stomach to prepare for the exam." From then on, her health-preserving recipes became his secrets for preparing for the exam, and his road to the imperial examination was steady step by step because of her way of nourishing himself. From a market stall owner to a county magistrate's wife, from a wonton stall to a health-preserving academy, the two of them joined hands to use the word "food and nourishment" to regulate one's body and mind and bring blessings to the people. This is a heart-warming story written about nourishing good relationships through food. Food and health are intertwined with imperial examinations and career, explaining the simplest truth - eat well, live seriously, and love and kindness will blossom and bear fruit.
