2How do I find it on my body?
- Take the navel to the xiphisternal junction as 8 B-cun.
- Go up 3 B-cun from the navel.
- Move out to the 4 B-cun line (the nipple line).
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.
- external abdominal oblique
- The widest, outermost muscle on the side of the belly. Its fibers slant like hands slipped into front pockets (from upper outside to lower inside), and it twists and bends the trunk.
- xiphisternal junction
- Where the body of the breastbone meets the xiphoid process, just above the pit of the stomach. From here to the center of the navel is taken as 8 cun.
- transversus abdominis
- The deepest of the three side-belly muscle layers. Its fibers run sideways like a belt and squeeze the belly in.
- rectus abdominis
- The long vertical muscle on each side of the middle of the belly, from the pubic bone to the rib cartilages, that bends the trunk forward. It makes the 'six-pack' blocks when tightened.
- internal abdominal oblique
- The second layer of side-belly muscle, just under the external oblique. Its fibers run roughly crosswise to the external oblique, and it helps twist the trunk.
3Before you press
- Press the abdomen only gently, with several fingers or the palm.
- Do not press the abdomen during pregnancy.
- Sudden severe abdominal pain, especially with fever or vomiting, needs urgent care — call emergency services if needed instead of using acupressure.
- Avoid broken or swollen skin and press only to a comfortable level.
- Acupressure is not a substitute for medical care.
4How has it been used traditionally?
- The Zhenjiu Jiayi Jing records it as a meeting place of the Spleen channel and the Yin Link vessel — a historical classification, not a claim of effect.
From traditional texts — not a claim of effect.
5Alternative location
Chinese standard (2021) differs · China's 2021 standard measures the 8 B-cun above the navel from the tip of the xiphoid process instead of the xiphisternal junction (WHO). The cun count is the same, but each cun can come out slightly shorter, moving the point a little toward the navel.
