Location
On the medial side of the lower leg, in the depression in the angle between the lower border of the medial condyle of the tibia and the medial border of the tibia.
How to locate: With the knee flexed and the hip slightly turned out, run the thumb up the medial border of the tibia until it stops against the medial condyle; the point is in the tender hollow in the angle below the condyle.
Distances are in cun, a proportional unit — how to measure.
