Some acupuncture points have several traditional names, for example
tài yuān () and
gui xin () are two names used for the 9th acupuncture point on the lung meridian. The
World Health Organization (WHO) published
A Proposed Standard International Acupuncture Nomenclature Report in 1991 and 2014, listing 361 classical acupuncture points organized according to the fourteen meridians, eight extra meridians, 48 extra points, and scalp acupuncture points, and published
Standard Acupuncture Nomenclature in 1993, focused on the 361 classical acupuncture points. Each acupuncture point is identified by the meridian on which it is located and its number in the point sequence on that channel. For example,
Lu-9 identifies the 9th acupuncture point on the lung meridian. The only ambiguity with this unique systemized method is on the urinary bladder meridian, where the outer line of 14 points found on the back near the spine are inserted in one of two ways; following the last point of the inner line along the spine () and resuming with the point found in the crease of the buttocks (), or following the point in the center of the crease of the knee () and resuming with the point just below that (), found in the bifurcation of the
gastrocnemius muscle. Although classification of the extra points often tries to utilize a similar shortcut method, where a numbered sequence along an assigned body part is used, there is no commonly agreed-upon system and therefore universal identification of these points relies on the original naming system of
traditional Chinese characters. The tables in this article follow the WHO numbering scheme to identify the acupuncture points of the main channels. For extra points the tables follow the numbering scheme found in
