1Where is Yuzhong?
Front of the chest, 2 B-cun out from the front midline, in the first intercostal space.
Sternocostal head of pectoralis major muscle · Costal cartilage of second rib · Second rib
2How do I find it on my body?
- Width scale: nipple to nipple is 8 B-cun, so midline to nipple is 4 B-cun and 2 B-cun is halfway.
- Find the ridge across the upper breastbone (sternal angle) — the 2nd rib sits beside it.
- The gap just above that rib, between the 1st and 2nd ribs, is the 1st intercostal space.
- Press where the 2 B-cun line meets that space.
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.
- 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
- 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.
4How has it been used traditionally?
- A Kidney meridian point on the chest; the Zhenjiu Jiayi Jing lists it among the spots where Kidney-channel qi surfaces — a historical description, not a claim of effect.
- The name is usually translated as 'Lush Centre'.
From traditional texts — not a claim of effect.

The gap just above that rib, between the 1st and 2nd ribs, is the 1st intercostal space. Press where the 2 B-cun line meets that space. it is about halfway between CV20 and ST14.
What should I watch out for?
