The correct method for bloodletting at the Commission Center point is puncture, and care needs to be taken with the depth of the puncture. It is located at the midpoint of the popliteal transverse stripe, in the middle of the biceps femoris tendon and semitendinosus tendon. Bloodletting at this point can activate blood circulation, remove blood stasis, dredge the meridians and other effects, and can treat lumbar pain, hip joint activity is not favorable, lower limb paralysis (lower limb weakness, numbness and pain) and other diseases. The specific operation method is to use three-pronged needles to puncture bleeding, but need to avoid puncturing too deep, otherwise it may lead to more bleeding. If blood-letting treatment is needed at the commission point, it should not be operated by oneself to avoid adverse effects on the body. You should go to a regular hospital and have it done by a professional doctor. After bloodletting, pay attention to local hygiene, keep the skin clean and avoid infection.
