Location
On the anterolateral lower leg, at the lateral border of tibialis anterior, 8 cun above the prominence of the lateral malleolus — one finger-breadth lateral to ST38 (two finger-breadths lateral to the anterior crest of the tibia).
Focks' Atlas of Acupuncture places it at the same level and distance but between the extensor digitorum longus and peroneus brevis muscles.
How to locate: Find the midpoint of the line from ST35 to ST41 by spreading the hands; at that level, 8 cun above the lateral malleolus, the point is two finger-breadths lateral to the anterior crest of the tibia, one finger-breadth lateral to ST38, at the outer edge of tibialis anterior. Choose the most tender spot.
Distances are in cun, a proportional unit — how to measure.
