A Stick of Incense (Also Known as "Farewell in the Distant Mountains")

A rebellious and arrogant medical student, when he was tired of medical life, met a middle-aged professor in the hospital who was erudite, low-key, calm, and kind-hearted. From then on, he was deeply impressed by the professor's personality charm. The student was grateful to the professor for saving his life, and after discovering the professor's secret, he worked hard to get into the professor's graduate program. In the life-and-death struggle and in scientific research, the two learned from each other from apprenticeship to teaching, from academic research to the vagaries of life, and became intimate lovers who talked about everything. They are both teachers and friends, they know each other in life and death, and they are moved by the world. Where will they go? Conception:
