The big frame fell into the heart

"Instructor Mao, you have to help." A middle - aged man was standing at the door of Mao Chi's house, constantly bowing and begging.

His attitude was very humble, even a little humble, even more so than when he had worked at 912 many years ago.

The exquisite, well - ironed suit was just like his, a little wrinkled and humble.

"Little Zhang, you ..." Mao Chi, the director of the Department of Cardiovascular Surgery, was a little embarrassed, but it was not difficult to say yes to the professor who used to be his subordinate.

Professor Zhang had been working in the ambulance for many years. After he was transferred from the military to a civilian, he was poached by a private hospital and became the director of the Vascular Surgery Department there.

In the past few years, professor Zhang had been doing his work fairly well. He was a cautious person and never started any risky new projects. He only did what he was good at.
