You must choose carefully to lose weight, and the acupoints must be professional. I did it in Wang Dafu Weight Loss Institute on Garden Road and Nongye Road. It's all professionally done by people with national doctor's certificates, and I'm quite relieved. I haven't bounced back from 140 there for half a year to 106 now. I feel very comfortable and sleep well every time I finish it. The phone number seems to be 87093892. I hope it helps you.
