　　Magic needles: Chinese acupuncture①

　　One of the most famous Chinese medical treatments is the art of 'magic needles'， or Chinese acupuncture.It was developed long ago, perhaps as early as 2000 BC.There is evidence that acupuncture began during the Stone Age, when stone tools called bian (砭) were used to press areas of the body②.

　　As acupuncture developed③， the simple bian stones were replaced by stone needles.Eventually④， metal needles began to appear and took their place⑤.There were nine different kinds of needles.These included a needle with a head like an arrow, used for making shallow⑥ holes in the surface of the skin; a needle with a round tip, used for pressing the tissue under the skin; a dull⑦ needle, used for tapping against pressure points⑧； and a needle like a small sword⑨， used for⑩ letting liquid out⑪ of body parts which had swollen up⑫.These needles could be made of⑬ different metals, such as gold and silver.Some acupuncturists⑭ today still use gold and silver needles, but the majority⑮ use only stainless⑯ steel ones.The main needle now used for acupuncture is fine⑰ and sharp⑱.Most of the others have been replaced by more complex⑲ medical instruments.For example, the needle looking like a sword has been replaced by a sharp knife that doctors use in operations⑳. 　　①acupuncture/'ækjʊpʌŋktʃə(r)/n.针刺疗法
