This is my thirty years of research and experience. The human body is originally balanced, but the patient's body is unbalanced. There is a raised meridian belt on one side of the back, which is particularly painful to press. This is a precursor to blood vessel blockage. No pain on the other side? Can't be found out by modern medical CT and laboratory tests? After many times of massage and other treatments, the painful meridians disappeared, the patient recovered, and the human body is in balance. There is no limit to learn, so I marked the patient's dysmenorrhea belt with a red line for your reference. And applied for a patent in Europe.
