《黄帝内经·灵枢·玉版》
治病如同治国，等到身体已经患了痈疽之病，以致大脓恶血已经形成，这时再用小针治疗，这不是离为医之道太远了吗？
夫至使身被痈疽之病，脓血之聚者，不亦离道远乎？
Treating illness is like governing a country. When the body has already suffered from carbuncle disease, to the point where a large amount of pus and bad blood has formed, can it not be said that it would be too far from the way of medicine to use small needles for treatment at this time?
