Generally speaking, it is not difficult to make an appointment with Beijing Medical University. It depends on the relationship. You can register directly. I am a student of Beijing Medical University, and I have been with my classmates several times. If it's an expert number, if it's from other places, you have to arrive one day in advance, and then there will be a queue at about three or four o'clock. You can usually arrive. We all go temporarily, and we can hang up, but the waiting time is long, so it is relatively difficult to hang up the Concord. So it's better to report to Beijing Medical University.
