Yes, your friend recommended Zheng, the first gynecologist in Xiamen. He is the attending doctor of Chang Gung Memorial Hospital. He is very famous. He also went to Korea for further study, and also went to the diagnosis and treatment of pelvic floor diseases and the research on female reproductive recovery. If you want to find a good doctor in a regular hospital, I suggest you find him in urinary incontinence, uterine prolapse, anterior and posterior vaginal wall bulging, perineal body laceration and vaginal contraction, hymen repair, labial plastic surgery and so on.
