What is a military doctor?
"All doctors, medical soldiers, sanitary workers and any other military personnel involved in medical services can be called military doctors. A military doctor is a soldier first and a doctor second, or you could say a soldier who supports with medical skills. We are very different from the cultural civil servants of the art troupe who sing and dance, and also different from the civil servants working in military offices." This is not something Guo Xiuying said, but the words of Wang Sanbao, a senior member within the medical corps.
Feng Qingxue is proficient in traditional Chinese medicine, and she is, of course, skilled in emergency care, treatment of wounds, and bone setting. However, she is well aware that surgical operations, including those on the battlefield, are her weak points — she has no experience whatsoever.
So, as soon as her job was settled, she asked for training.
