You don't need an ID card or a parent's signature. The doctor will ask how old you are. If you are under the age of 22, you will be asked to sign a risk commitment letter, that is, if you are still young, you need to know that you have responsibilities and need friends to accompany you. It is better to be a girl, because men are not allowed to go to obstetrics and gynecology, and it will be very painful to finish the operation. The whole set needs your help (the price of general anesthesia is different from that of general anesthesia, which is the most expensive). In addition, after you finish, you will be given some drug protection.
