Acupuncture and massage are both traditional medical arts of Huaxia, and they both start with the human body's meridians. They are considered to be branches of the same tradition, which is why many doctors who use these traditional Huaxia medical techniques are skilled in both acupuncture and massage. Moreover, they often use them in combination, supporting and enhancing the effects of one another.
