Do you want to ask Dr. Huier Xu Hongyi in Hangzhou? Is he a professional?

Dr. Xu is a returnee with a Ph.D. in audiology from the University of Wisconsin. He has worked in many famous medical centers in the United States, specializing in the research and development of hearing AIDS, cochlear implants, electrophysiology, tinnitus, dizziness and hearing problems. He is a very professional and famous expert, and many people have invited him. I came to Hangzhou with my family to see my ears before, and finally made an appointment.
