The medical spirit of the Second Hospital of Harbin Medical University is very poor. It is common for doctors to accept tips, and it is unscrupulous. For example, Liu Ming (or the director) of the Department of Otolaryngology had vocal cord polyp surgery more than three years ago, because the patient didn't give a tip (because he had something to do the day before, did he meet him on the day of surgery? The tip was put in his pocket and went into the operating room, but he was anesthetized first. Results a piece of meat was embedded in the upper part of the tongue root, which was unbearable and had sequelae after recovery. Liu Ming has no medical ethics, which is despicable. At that time, I wanted to sue him, but at that time, the patient could not speak (recovered after vocal cord surgery) and his relatives were not around. In addition, I also know that people in this world are hard to argue, so we will let nature take its course.
