The teenage Qin Mu went into the Zhongnan Mountains at a young age, following the reclusive old Mr. Sun to study diligently for ten years, acquiring solid skills. Entering the department by chance, his unique medical practice habits caused quite a few fun incidents. Lacking a formal institutional learning experience, he faced doubt from many colleagues. But relying on the keen insight and skilled techniques tempered by years of experience, Qin Mu repeatedly resolved acute emergencies and saved critically ill patients. Facing criticism and misunderstandings, he stuck to the benevolent heart of a medical practitioner, and with the support of his partners, devoted himself to self-improvement, grasped the true meaning of heritage, broke through prejudice, and guarded thousands of patients at the emergency post.
