1Where is Qihu?

Just below the collarbone, 4 B-cun out from the front midline.

It is on the upper front chest.

Beneath the point

Clavicular head of pectoralis major muscle · Subclavius muscle · Clavicle

Our 3D measurement · In our 3D model: on the horizontal line of the lower border of the clavicle (same height as KI27, CV21 and LU2), 4 cun (83.2 mm; 1 cun = 20.8 mm) from the front midline; 2.0 mm below the clavicle's lower edge measured right at the 4-cun line.

2How do I find it on my body?

Run a fingertip along the lower edge of the collarbone.
Take the 4 B-cun line from the midline. It is half the 8 B-cun between the nipples, so in men it is the nipple line.
Press where the two lines meet.

Check · KI27 and CV21 sit further in at the same level; LU2 sits further out.

What is a “cun”?

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.

📖 Words explained

clavicular head of pectoralis major: The top part of pectoralis major, starting from the collarbone. It works when you raise the arm forward and up.
chest wall: The wall around the chest organs, made of skin, muscle, ribs and the muscles between them. In places it is thinner than you might think.

3Before you press

⚠ Do not press when

The pleura and lung lie just beneath the chest wall here.
Do not jab with pointed tools or dig in deeply.
Sudden breathlessness or chest pain is an emergency — call emergency services; do not try 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 name joins qi and hu (door): a doorway of breath. WHO notes it lies on one horizontal line with KI27, CV21 and LU2.

From traditional texts — not a claim of effect.
