Three-and-a-half-year-old Shen Tuantuan rides a short-legged corgi and carries a herbal pouch as she comes from the countryside to the Grand Marshal's mansion to find her relatives. Innocent, meticulous, and daring, relying on the herbal skills taught by her grandmother and accompanied by her small animal friends, she helps her family regulate their health, resolves misunderstandings, and brings the family closer together. From an unfamiliar country girl to the sixth young lady cherished by the entire mansion, Tuantuan wins the love of her four brothers with her kind smile and awaits her own reunion.
