Location
On the dorsal aspect of the forearm, 5 cun below the olecranon, between the radius and the ulna.
Focks' Atlas of Acupuncture measures it 7 cun above the dorsal wrist joint space, in the depression between the extensor digitorum and extensor carpi ulnaris muscles.
How to locate: With the forearm pronated, measure 5 cun down from the prominence of the olecranon along the back of the forearm; the point is in the depression midway between the radius and the ulna.
Distances are in cun, a proportional unit — how to measure.
