Location

On the medial side of the foot, in the depression below the tuberosity of the navicular bone, at the border between red and white flesh.

Focks' Atlas of Acupuncture places it in the depression at the anterior border of the navicular bone, at the lower angle of its joint with the medial cuneiform, rather than below the navicular tuberosity.

How to locate: Run a finger back along the medial arch of the foot past the first metatarsal and the medial cuneiform until it meets the prominent tuberosity of the navicular bone, in front of and below the medial malleolus. The point is in the depression just below the tuberosity, at the red and white flesh border.

Distances are in cun, a proportional unit — how to measure.
