Hollow point punching is a commonly used technique in Chinese medicine massage, and its main function is to relax tight muscles and dredge meridians. Through rhythmic beating, the acupoints vibrate, and then the purpose of dredging meridians and relaxing muscles is achieved. Compared with solid boxing, hollow boxing has less stimulation, higher patient compliance and better vibration effect. At the same time, the main purpose of meridians is the penetration of vibration, not the power of hitting, so hollow boxing is more suitable for hitting acupoints.
