Dr. Hang is really a healer. He cured my chronic cough and asthma within one month. I never thought acupuncture can help asthma until I got a referal from my family doctor to this place. He gave me 5 acupuncture sessions totally and prescribed me some herbal tea. Just one week later my chest tight problem is gone. The whole month I don't have any asthma attack which usually happened every week. I highly recommend dr. hang to anyone with cough or asthma problem. By the way, I don't know acupuncture is so comfortable too before I came to dr. Hang. I feel deeply relaxed and my sleep quality is improved a lot.
