To answer you clearly, acupuncture should be diet and exercise. For xi 'an, there are two places where acupuncture is good, Shaanxi College of Traditional Chinese Medicine, Xihuamen Cross in North Street, Xi 'an Chinese Medicine Hospital and Dachaicheng. These two places are the most professional in acupuncture. You can't drink or eat a lot of things when sticking acupuncture, because Chinese medicine pays attention to taboos when treating!
