Location

On the medial side of the foot, in the depression distal and inferior to the first metatarsophalangeal joint, at the border between red and white flesh.

How to locate: On the medial side of the great toe, slide proximally along the proximal phalanx toward the first metatarsophalangeal joint; the point is in the depression just distal to the step formed by the base of the phalanx, slightly toward the sole, at the border of red and white flesh.

Distances are in cun, a proportional unit — how to measure.
