FAQ

1Where is Quepen?

In the greater supraclavicular fossa, just above the collarbone.

It lies 4 B-cun out from the front midline.

It is low at the side of the neck.

Beneath the point

Omohyoid muscle · Subclavian artery · Clavicle

Our 3D measurement · In our 3D model: skin on the 4-cun line over the space between the clavicle and the omohyoid (greater supraclavicular fossa); 9.2 mm above and 5.9 mm behind the top of the clavicle.

2How do I find it on my body?

Find the large hollow above the middle of the collarbone (greater supraclavicular fossa).
Take the line 4 B-cun from the front midline. In men, it rises straight from the nipple.
Press where that line meets the hollow just above the collarbone.

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

greater supraclavicular fossa: The wide hollow above the collarbone, behind and outside sternocleidomastoid. It deepens when you hunch the shoulders.
subclavian artery: The large artery that passes under the collarbone toward the arm. After it crosses the outer edge of the first rib it is called the axillary artery.

3Before you press

⚠ Do not press when

The top of the lung and large vessels and nerves pass deep in the hollow above the collarbone.
Do not dig in with a fingertip; press gently only.
Stop if the arm tingles or you feel short of breath.
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?

Quepen (broken bowl) was also the classical name for the hollow above the collarbone itself.
The Zhenjiu Jiayi Jing already warned against deep needling here.

From traditional texts — not a claim of effect.
