Lin Xinyi, a famous Chinese medicine practitioner in Tianhua City, is proficient in the long-lost "Silver Needle Nine Turns to Yang Needle", but she is misunderstood by the world as a "dirty doctor" because she only treats the rich. In fact, Lin Xinyi has a kind heart. She will use all the medical fees she earns from wealthy people to fund poor patients and charitable organizations. Overseas biotechnology giant Chen Zhiyuan came here because of her reputation, hoping that Lin Xinyi would use traditional Chinese medicine to treat his wife Li Meina, who suffers from systemic lupus erythematosus, and gave her a priceless mutton-fat white jade Guanyin Pendant as a medical fee. While Lin Xinyi was preparing medicinal materials, her mother Zhao Yulan and her 8-year-old son Lin Xiaoxuan were bullied by Li Meina at the intersection of Huating Street.
