Location

On the posterior shoulder, 1 cun above the posterior end of the axillary fold with the arm adducted.

How to locate: With the patient seated and the arm hanging against the side, measure 1 cun straight up from the end of the posterior axillary fold.

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