Location
On the anterior midline, 3 cun inferior to the sternocostal angle.

How to find
The distance between the sternocostal angle (➞3.5) and the
centre of the umbilicus is divided into 8 cun, which can vary
considerably from the patient’s finger cun. Therefore, only pro-
portional cun measurements should be applied here (helpful
device: elastic tape ➞2.3.1). From the sternocostal angle, meas-
ure 3 cun in an inferior direction and there locate Ren-13on the
anterior midline.
Located on the same level are ➞KID-20(0.5 cun lateral to the
midline), ➞ST-20(2 cun lateral to the midline) and ➞G.B.-24
(approximately on this level, in the 7th intercostal space, on the
mamillary line).

Needling
Vertically 0.5–1 cun. Caution: Peritoneum, pregnancy.
