    In five element acupuncture this point is reinforced to tonify Small Intestine deficiencies.

    Ling Shu Ch. 19, on the Four Seasonal Qi, advises using the Shu-Stream points, unless the diseases are in the Fu organs, in which case the He-Sea points are chosen.

    Ling Shu Ch. 23, On Heat Diseases, gives a different list of points for the "59 Piercings" to Su Wen Ch. 61. They include three on the outer and three on the inner side of the hands which most likely includes this point.

    In Tung acupuncture the Wan Shu Yi, Wrist Flow One, point is located slightly proximal to this point. Its indications seem similar to this point echoing the Du and Taiyang channels (Back, neck, shoulder, arm, hip and side of foot pain, dizziness, vertigo, tinnitus and urinary disorders). It is often combined with Wan Shun Er, slightly distal to Wangu SI-4 (Chu, 2015).

    Yuen (2005, The Eight Extraordinary Vessels) notes that this point, along with Zulinqi GB-41, is a Shu-Stream point instead of a Luo point like all the other extraordinary vessels because the Du, along with the Dai mai, are concerned with projecting out into the world while the other extraordinary vessels are about taking in from the outside world.
