4 cun above and slightly anterior to the tip of the external malleolus, on the anterior border of the fibula.
How to locate
Identify the tip of the lateral malleolus as the reference point. Measure 4 cun from there and locate Yangfu GB-38 on the anterior border of the fibula.
The borders of the fibula are deep to the peroneus brevis muscle and are often not easily palpable. For this reason, it is suggested to palpate the anterior border of the fibula just superior to the ankle and then locate the point on an imaginary line running to the head of the fibula.
