New interpretation of "Miu Ci".

Based on the record of Miu Ci theory from Huangdi Neijing (The Yellow Emperor's Internal Classic), and incorporating the relevant discussions of medical scholars from various dynasties, this article interprets and analyzes the Miu Ci technique, the points to be needled, and the diseases can be treated. The following innovative understandings are proposed： 1) The original meaning of "Miu" in Miu Ci is "to prick in a different way from the meridians (needle the major collaterals)", not "needle left and right interchangeably". Needle left and right interchangeably is not a necessary operation in Miu Ci. 2) The stimulation sites of Miu Ci are the "four extremities" of the human body, referred to as the "major collaterals of qi", and the nail bed of the four extremities is not equivalent to the commonly reco-gnized "Jing-well points". 3) Miu Ci can treat critical illnesses, not just limited to musculoskeletal pain or mild conditions at the early stage of a disease. 4) Miu Ci is not equivalent to Luo Ci needling (pricking bloodletting therapy).
