2How do I find it on my body?
- Make a loose fist so the knuckles stand out on the back of the hand.
- Move from the ring-finger knuckle toward the wrist.
- Press the dip between the fourth and fifth metacarpals.
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.
3The classical posture
- Make a fist (the classical "closed hand").
- From the ring-finger knuckle on the back of the hand, move toward the wrist.
- Press the hollow between the fourth and fifth metacarpals.
4Before you press
- Avoid broken or swollen skin and press only to a comfortable level.
- Acupressure is not a substitute for medical care.
5How has it been used traditionally?
- Classified as the Shu-stream (Wood) point of the Triple Energizer meridian — a historical classification, not a claim of effect.
- The name means 'middle islet' (a sandbar in a stream).
- The Donguibogam, quoting the Song-dynasty Tongren, locates it with the hand closed into a fist.
From traditional texts — not a claim of effect.
