Local people in Lanzhou know that the big plastic surgery hospital in Lanzhou is Lanzhou Aimei Accompanied Plastic Surgery Hospital. Many people go there. I lost my hair for a long time because I didn't know I could make an appointment in advance. If your friend goes, please make an appointment for her online first, so you don't have to wait in line. The address is here. . . . Poly Building, Zhangye Road.
