Location

On the upper abdomen, 5 cun above the umbilicus, 2 cun lateral to the anterior midline.

How to locate: Treat the distance from the sternocostal angle to the centre of the umbilicus as 8 proportional cun and find its midpoint (CV12); go 1 cun up and then 2 cun lateral, level with CV13. With a narrow costal angle the point may lie on the lower border of the rib cage.

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