1Where is Jianzhongshu?

Upper back, 2 cun out from the back midline, level with the lower edge of the seventh cervical spinous process.

Beneath the point

Seventh cervical vertebra · Trapezius · Levator scapulae

Our 3D measurement · In our 3D model: at the lower end of the C7 spinous process, 2 cun (41.3 mm) from the back midline.

2How do I find it on my body?

Bow the head and find the most prominent knob (C7).
Draw a level line just below it (where GV14 lies).
Divide the span from the midline to the inner border of the scapula (3 cun) into thirds.
Press where the 2-cun mark meets the level line.

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

levator scapulae: A strap-like muscle on the back side of the neck, linking the upper neck bones to the top corner of the shoulder blade. As its name says, it lifts the blade.
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.
