Su Nianwei, a folk chef who possesses the secret technique of "Therapeutic Materia Medica" passed down from her family, will step into Prince Jing's Mansion by chance. Faced with the frail and sick cold-faced prince Xiao Heng and the "five flavors imbalance" in the palace's diet, she used food as a medicinal stone and used the principle of "the five elements return to the meridians" to skillfully adjust the medicinal diet for the four seasons. Starting from a bowl of clear and moist autumn lotus root soup, she worked step by step to improve the palace's secret recipe, establish a "dietary conditioning bureau", compile "Prince's Dietary Therapeutic Prescriptions", and quietly plucked the heartstrings of the cold noodle king with her nourishing skills. This is an innovative journey about food, health and long-lasting emotions. The harmony of the five flavors on the tip of the tongue is also when the heart gradually warms up.
