Location

On the head, in the depression at the medial end of the eyebrow, directly above BL1, where the frontal notch can often be felt.

How to locate: Use the inner canthus (BL1) rather than the variable eyebrow as the guide: go straight up to the orbital ridge at the medial end of the eyebrow and feel for the frontal notch, usually a tender depression.

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