Notes:

The Stomach Shu are a proposed set of points that complement the Breast Shu. They are level with the Chest Shu and Front Mu points on the abdomen and receive the Blood and Ying Qi created through the action of the Spleen and Lung, via the Breast Shu, to distribute among the Zangfu. Whereas the Back Shu and Chest Shu deliver Yang and Yin Yuan Qi through the Bladder and Kidney Channels to the Zangfu, these points are focused specifically on postnatal Qi.

This point would be associated with the Gallbladder, being in line with Riyue GB-24 and its indications being to harmonise the Middle Jiao, implying Shaoyang disharmony.
