Last time, my father-in-law's nose root was swollen, which was caused by suppuration of false teeth. I didn't know at first, so I took him to the Otolaryngology Department of Xinglin Branch and hung up the number of a chief assistant doctor. As a result, I was asked to have a CT scan without much examination. I wanted to do it, but I checked for a long time. As a result, the CT doctor said that I couldn't do it because the doctor didn't clearly write down the specific location of the CT scan, only wrote that the nasal root didn't know where to shoot it, and then went to the private stomatological hospital in less than 1 hour. When returning to Xinglin Branch to refund CT money, only the doctor who made the bill can refund it until the doctor goes to work next time. From then on, I will never go there to see a doctor again.
