Bianshu is the first of the four medical skills (Bianshu, Acupuncture, Moxibustion and Medicine) that existed independently in ancient China. It is the oldest medical skill in China. It uses special stones to carry out medical care for the meridians on the body surface. It is the predecessor of acupuncture, massage, massage and scrapping. According to Bian Cui. Biancui is a special stone used to treat diseases. Generally, it is not necessary to puncture the skin to treat diseases with flat Cui. Its method was called transformation in ancient times. The ancients did not cure the disease, which can be found in the "Shan Hai Jing Dong Shan Jing": "When the mountains moved, there were many jade, and the mountains were rocky"; Shuowen is "stabbing a disease with a stone". After long-term practice, people have established the treatment principle of "taking pain as damage" and invented acupuncture therapy. But needles never pierce the skin. For example, in the original chapter of the Nine Chapters of Lingshu, it is said: "The needle is oval, so it should be rubbed between (meat) without hurting the meat." As can be seen from the above, the needle is a round object made of stone by Spencer, which is placed on the acupoint without hurting the flesh. Bian needle is the originator of traditional Chinese medicine.
