On the fibular (lateral) aspect of the lower leg, 5 cun above the prominence of the lateral malleolus, just anterior to the fibula.
How to locate: Measure 5 cun above the prominence of the lateral malleolus (a hand's breadth plus two thumb-widths, or 2 cun below the midpoint of the line from GB34 to the malleolus); the point is in a depression at the anterior border of the fibula, traced up from just above the ankle.
Distances are in cun, a proportional unit — how to measure.
