After graduating from university a few years ago, I asked my father's friend to help me and found a construction site near Jing'an Temple in a hospital in downtown Shanghai. It was not far from my home. It was about 30 minutes away by bicycle.

Moreover, orthopedic surgery is a relatively few medical risks in the surgical system.
