Her maternal grandfather was slowly poisoned and lost his mental faculties. She struggles to make ends meet while running Zhi Ji Medicinal Cuisine on the old street with her daughter, Wen Tangtang. Xie Zhiwei, the daughter of Xie Linyuan, president of the Xie Group, suffers from a severe form of infantile malnutrition. For three years, she has been unable to eat normally and has developed a fear of white coats. By chance, she sneaks a hawthorn pill from Wen Zhi's shop and manages to speak. Xie Linyuan asks Wen Zhi to treat his daughter, offering to protect the old street from demolition and give her access to Yiniantang's archives in return.
