Lin Fei, a novice surgeon, walked into a tertiary tertiary hospital with ideals. What greeted him were endless shifts, trivial medical orders, complex interpersonal relationships, and crises that could come at any time. Working with the calm and dedicated cardiologist He Wanting, the humorous and tenacious head nurse Zhou Dexin, the "knife-tip dancer" Tang Shuo and others, he struggled all the way on the road to saving people and himself. The friendship between the medical team, the ambiguous and bright feelings between each other, the family test brought by the patient's family and the pressure of public opinion are intertwined into a mixed life. Cases, pain, jokes, misunderstandings and sincerity all flow between the alcohol-filled night shift and early morning ward rounds. In the four volumes, they broke out, struggled, healed, and moved forward under heavy pressure. Finally, in an unexpected public health crisis, they used courage and humor to achieve personal and collective breakthroughs and transformations.
