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

    Ling Shu Ch. 19, on the Four Seasonal Qi, advises opening the Jing-Well and Ying-Spring openings in winter, piercing deeply and retaining the needle for a while.

    Ling Shu Ch. 24, On Counterflow Diseases, advises using this point on the opposite side for sounds in the ears. It then advises using the equivalent points on the feet.

    Ling Shu Ch. 44, On the Qi Moving in Accordance with the Norms, indicates that the Jing-Well points should be pierced in winter or when the disease is in the Zang organs. The seasonal aspect should not be interpreted literally as it describes the nature of winter as the the time of storage and the Zang as "controlled by winter" (i.e. to be storage depots by nature). It also describes the morning, afternoon, evening and night cycle of the day to be like the four seasons of the year with night corresponding to winter. Only five channels are discussed so this point must have served the for the Heart too.

    Another two points Er Jiao Ming, Two Corner Bright, are located further down the middle finger, also on the dorsal aspect on the hand but at the proximal segment, the first 1/3 of the distance from the proximal crease and the second 2/3 of the distance from the proximal crease. They are indicated for pain of the lower back or face, especially the face (Chu, 2015).

    In Siddha medicine some practitioners consider this a "whole body relief spot" (carvanka atankal) able to stimulate all vital spots at once when opened by a jerking sharply (Sieler, 2015, Lethal Spots, Vital Secrets, p.87).
