Location

On the lateral side of the distal phalanx of the fourth toe, 0.1 finger-cun proximal to the lateral corner of the nail, where a line along the lateral border of the nail meets a line through its base.

How to locate: Imagine one line along the lateral border of the fourth toenail and another along its base; the point is where they cross, about 0.1 cun from the corner of the nail.

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