2How do I find it on my body?
- Trace the lower edge of the clavicle from the sternum toward the shoulder.
- Near the shoulder, press in until you meet a firm knob: the coracoid process.
- Press the soft hollow just inside it (toward the midline).
- infraclavicular fossa
- The hollow below the outer part of the collarbone, between deltoid and pectoralis major. The coracoid process can be felt deep in its floor.
- coracoid process
- A hook of bone curving forward from the shoulder blade like a bird's beak. You feel its hard tip deep in the hollow below the outer part of the collarbone, at the front of the shoulder.
- pectoralis major
- The large fan-shaped muscle covering the front of the chest. It runs from the collarbone, breastbone and rib cartilages to the top of the humerus, and it tightens when you bring the arm forward or hug.
3Before you press
- The lung lies deep to this spot.
- Do not jab with pointed tools.
- If you suddenly become short of breath or have chest pain, do not try acupressure — call emergency services or get medical care.
- Avoid broken or swollen skin and press only to a comfortable level.
- Acupressure is not a substitute for medical care.
4Alternative location
Chinese standard (2021) differs · The Chinese standard (GB/T 12346-2021) places this point at the inner edge of the coracoid process and measures chest width with a 12-cun span between the two coracoid inner edges (WHO uses 8 cun between the nipples), so the two rulers can disagree on broad or narrow shoulders. It leaves out WHO's extra note that LU2 sits mid-way in the deltopectoral triangle.

How do I find Yunmen?

Press the soft hollow just inside it (toward the midline). raise the arm forward and slightly out against resistance. A small triangle appears between the deltoid and pectoralis major (deltopectoral triangle); Yunmen is close to its centre. This can shift with shoulder width.
