Regular hospitals need blood. It seems to be to see if the content of things in your blood is suitable for surgery. But personally, I think it can basically be done. It's just an excuse for the hospital to overcharge. But there is not much money, so let's do it. You can ask the hospital to buy things for you for free. Not if it's your period on the day of surgery.

Doing double eyelids will really make you beautiful. Do it. But we must find a regular hospital and find a good and experienced doctor in a regular hospital to do it. Some regular hospitals also have new doctors, so don't let yourself be an experiment for others.
