Generally, this cupping method is simple and convenient because most white-collar workers are busy and don't do such complicated things. Cupping can be done wherever it really hurts. As long as you know this, you can do cupping yourself. If you feel pain in your waist or shoulders, you can find the location of the pain and then cupping. If you can't find the specific pain location, you can do cupping on this line of the spine. The large tank has strong suction, and can be pulled out for 5 to 1 0 minutes per time, while the small tank has weak suction, and can be pulled out for 10 to 1 5 minutes per time.
