Of course, if I understand your mood, I can introduce you to a method of cupping to lose weight, but it's just for reference. If it works, it's just the right thing to do. If it doesn't work well, there's nothing I can do. In fact, many attempts to lose weight by acupuncture or cupping are ineffective and basically "not symptomatic". I don't know what methods are used in beauty salons. The following recipes add some notes to the information.
Cupping to lose weight and acupoint selection reference:
Back: Huatuo Jiaji point (chest 1 to waist 5, 0.5 inch sideways); Abdomen: Shu Tian, Daheng, Qihai and Guanyuan; Legs: Liang Qiu, Zusanli, Hong Long, Xue Hai; Foot: Gongsun, etc.
Note: Leave the cylinder once a day for 10~ 15 minutes, not too long, otherwise it may cause bleeding bubbles (especially on the back). I can't find the specific acupoints, so I suggest you search the acupoints map. Sometimes the narrative is not clear, so it is very simple to find someone who knows the meridians.
