Oh, I did it at Xi Chen's house. It's called physiological double eyelids, which was made by their dean. At that time, I made it clear that I wanted the dean to do it. I thought the dean was the best. Of course, this is my own idea. I was a little swollen after doing it, and I was a little worried, but the swelling went down in about 3 days, but I waited about 10 days to see the effect. I am a person with slow recovery time, and some people recover well in a few days. Maybe it has something to do with personal physique. Friends still feel quite good after reading it. I suggest mlalm go to Xidan personally to ask questions, aiming at personal problems.
