In Yunxi Town, a water town in the south of the Yangtze River, Cheng Wanqing, the successor of Huichun Hall, a century-old medical clinic, is gentle, tough and has superb medical skills. Xie Jingxing, the young master of the Xie family, is cold and arrogant, but he is forced to receive regular medical treatment from her due to an old illness. The fragrance of medicine lingers, the smoke of tea lingers lightly. During the consultations and consultations, the two of them went from alienation to trust. He is arrogant and aggressive, but she handles it calmly; he hides his concern, but she is gentle and persistent. In each storm, she broke through with her kindness, and he protected with his actions. With different identities and gradually connected hearts, a restrained and affectionate medical love in the Republic of China quietly blossomed in the bluestone alleys.
