Location
On the medial side of the lower leg, 6 cun above the prominence of the medial malleolus, just posterior to the medial border of the tibia (3 cun above SP6).
How to locate: Measure 6 cun up from the prominence of the medial malleolus (twice the distance to SP6), just behind the medial border of the tibia; alternatively, it is 0.5 cun below the midpoint of the line from the malleolus to SP9.
Distances are in cun, a proportional unit — how to measure.
