1Where is Geguan?

Upper back, 3 cun out from the back midline at the level of T7.

The level is set by the lower edge of the T7 spinous process.

Beneath the point

Vertebra t7 · Descending part of trapezius muscle · Latissimus dorsi muscle · Longissimus thoracis muscle

Our 3D measurement · In our 3D model: level with the lower tip of the T7 spinous process, 3 cun (61.9 mm; 1 cun = 20.63 mm) from the back midline.

2How do I find it on my body?

Stand with the arms hanging. A line joining the lower tips (inferior angles) of the shoulder blades crosses the midline at T7.
Take the height of the lower edge of that spinous process.
Press 3 cun out from the midline. With the arms hanging, this is the vertical line along the inner border of the shoulder blade.
If the blade covers the spot, fold the arms in front so the shoulder blades slide outward, then press.

Check · it is level with Geshu (BL17) and, on the midline, with Zhiyang (GV9).

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

descending part of trapezius: The upper part of trapezius. It starts at the back of the skull and neck and runs down to the outer collarbone, and it shrugs the shoulder up.
longissimus thoracis: The back part of the middle column of erector spinae (longissimus). As its name says it is long, and it straightens the lower and middle back.
spinous process: The bony spike sticking backward from the middle of each spine bone. The row of bumps you feel down the middle of the back is these, and they serve as the counting marks for back points.
latissimus dorsi: The broad muscle covering the lower back and sides. It runs from the lower back and pelvis, behind the armpit, to the humerus, and pulls the arm down and back, as in a pull-up.

3Before you press

⚠ Do not press when

Do not bear down hard on the spine or ribs with an elbow or a tool.
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?

Lateral to the diaphragm back-shu point (BL17); the name means 'diaphragm pass'. The Zhenjiu Jiayi Jing says to locate it sitting upright with the shoulders spread.

From traditional texts — not a claim of effect.
