Last year, my uncle had a tumor operation in this hospital. At that time, a doctor named Zhou operated on her. I'm not sure about the exact level, but I know that my uncle recovered well after he was discharged from the hospital. It's been almost a year, and there is no recurrence at present. I want to say that Shanghai Oriental Hepatobiliary Surgery Hospital is, after all, a military medical hospital and a third-class first-class hospital certified by the state. There must be many high-level doctors in it. You can find an attending doctor at will, and it should be the same.
