Personally, I don't think it's good to use slimming needles. In fact, if you want to stovepipe, I think this method is good. Lie on the bed with your legs together and your arms straight to support your body. Slowly press down the upper body with the strength of the body and lift the calf at the same time. When reaching the limit, keep this posture for a moment, then slowly restore the original posture and practice repeatedly until the body feels tired (slimming tea should drink it after meals). This exercise can make your body muscles strong, and it can also exercise your legs, so that you can easily slim out beautiful legs.
