1Where is Lingxu?

Front of the chest, 2 B-cun out from the front midline, in the third intercostal space.

Beneath the point

Sternocostal head of pectoralis major muscle · Costal cartilage of fourth rib

Our 3D measurement · In our 3D model: skin on the line 2 cun (41.6 mm) from the front midline, at the height of the third intercostal space read at that line.

2How do I find it on my body?

  1. Width scale: nipple to nipple is 8 B-cun, so midline to nipple is 4 B-cun and 2 B-cun is halfway.
  2. Find the ridge across the upper breastbone (sternal angle) — the 2nd rib sits beside it.
  3. The gap just below that rib is the 2nd intercostal space; count down from there to the 3rd.
  4. Press where the 2 B-cun line meets that space.
Check · it is about halfway between CV18 and ST16.
What is a “cun”?
What is a “cun”?

A cun is a body-scaled unit of length. The precise way is to divide a bone length into equal parts (proportional bone cun); finger widths are a quick estimate.

📖 Words explained
sternocostal head of pectoralis major
The large middle part of pectoralis major, starting from the breastbone and upper rib cartilages. It pulls the arm in toward the body.
intercostal space
The gap between two ribs, felt with a fingertip as a slight groove between bone and bone. It is named after the rib above it (the gap below the first rib is the first intercostal space).
costal cartilage
The firm cartilage that joins the front end of a rib to the breastbone. It is a little softer and more bendy than bone, so the chest can expand when we breathe.
sternal angle
The slight horizontal ridge where the manubrium meets the body of the breastbone; slide a finger down from the notch at the base of the neck and it catches on it. The second rib attaches right beside it, so it is the starting mark for counting ribs.

3Before you press

⚠ Do not press when
  • The pleura and lung lie close beneath the rib spaces — do not dig a fingertip in deeply.
  • Avoid broken or swollen skin and press only to a comfortable level.
  • Acupressure is not a substitute for medical care.
  • For crushing chest pain or sudden breathlessness, call emergency services at once; do not try acupressure.
