I don't have a good impression on Peking University Hospital, because my friend's sister was misdiagnosed by them (tumor, which was said to be curable before, was later said to be curable when it became malignant. Because it was a uterine tumor, the patient didn't want to remove the uterus, so he accepted it, and then the cancer spread all over the body. . . . ) But I heard that they are paid more and have more professors.
