Little Yaya, who has the ability to communicate with plants and trees, is legally adopted by the Gu family. Using her own life force, she heals illnesses and injuries, revives a withered ancient lotus and a century-old golden osmanthus tree, and helps her family. When rivals challenge them, believing in chemical extraction and looking down on traditional medicinal cuisine, the Gu family remains true to the principle that food and medicine share the same origin. With her pure kindness, Yaya resolves conflicts, and everyone works together to preserve and promote the traditional culture of Chinese medicine.
