Cupping is a kind of therapy with cupping as a tool, which generates negative pressure by burning and pumping air, so that it can be adsorbed on the body surface, causing local blood stasis, thus achieving the functions of dredging meridians, promoting qi and blood circulation, relieving swelling and pain, expelling wind and dispelling cold. Cupping therapy has a long history in China. As early as the Western Han Dynasty, there was a record of "angle method" in the silk book "Fifty-two Prescriptions for Diseases", which was similar to cupping therapy in later generations. Cupping therapy is also very popular in ancient Greece and Rome abroad.
