I just bought Qumei today, and I don't know how it works. I've tried, mostly to lose weight. I am a little lazy when I don't exercise, and I don't insist. Yoga is slow to lose weight, and the food is light, so acupuncture is of little use. Even high technology is deceptive. A while ago, I got a 10,000-yuan weight-loss card, and told Changfeng 3S that I was fat because of kidney deficiency, lymphatic obstruction and many spleen and stomach problems, but he didn't lose weight at all.
