Radius · Ulna · Posterior interosseous artery
2How do I find it on my body?
- Palm down, take the back wrist crease (the level of TE4) as the start line.
- Counting wrist crease to elbow as 12 cun, go 3 cun up (one quarter) — 1 cun above TE5.
- Press into the hollow between the radius and the ulna.
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.
- posterior interosseous artery
- A thin artery running down the back of the forearm between the radius and ulna. It supplies the muscles on the back of the forearm.
- wrist crease
- The horizontal crease that forms at the wrist when it is slightly bent. There is one on the palm side and one on the back, and they are starting lines for measuring arm points.
3Before you press
- 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?
- Classified as the Jing-river (Fire) point of the Triple Energizer meridian — a historical classification, not a claim of effect.
- The name means 'branching ditch'; zhi can also be read as 'limb' (肢).
From traditional texts — not a claim of effect.
