1 cun lateral to the anterior midline and 2 cun superior to the upper
border of the pubic symphysis.How to find
The distance between the centre of the umbilicus and the upper
border of the pubic symphysis is divided into 5 proportional cun,
which can vary considerably from the patient’s finger cun.
Therefore, only proportional cun measurements should be used
(helpful device: elastic tape ➞2.3.1). From the upper border
of the pubic symphysis, measure 2 cun in a cranial direction
(➞Ren-4) and, from there, measure 1 cun in a lateral direction.
There, locate yijing.
Located on the same level are ➞KID-13(0.5 cun lateral to the
midline), Ex-CA(qimen, 3 cun lateral to the midline), ➞ST-28
(2 cun lateral to the midline) and Ex-CA(tituo, 4 cun lateral to
the midline). ➞G.B.-27is located medial to the ASIS, approxi-
