1Where is Xuanji?

On the front of the chest, on the midline, 1 B-cun below the suprasternal fossa.

This is the same spot as 1 B-cun below CV22.

Beneath the point

Manubrium · Costal cartilage of first rib · Costal cartilage of first rib

Our 3D measurement · In our 3D model: on the front midline skin at the horizontal line of the lower border of the clavicle (same height as KI27, ST13 and LU2). It lies 8.5 mm (0.49 cun) below Tiantu (CV22), 9.0 mm higher than the main text's '1 cun below CV22' — still to be verified.

2How do I find it on my body?

Find CV22 at the centre of the notch above the breastbone.
Measure 1 B-cun down, using the chest scale (9 B-cun from the notch to the xiphisternal junction).
Press the middle of the top part of the breastbone (manubrium).

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

xiphisternal junction: Where the body of the breastbone meets the xiphoid process, just above the pit of the stomach. From here to the center of the navel is taken as 8 cun.
costal cartilage: The firm cartilage that joins the front end of a rib to the breastbone. It is a little softer and more bendy than bone, so the chest can expand when we breathe.

4How has it been used traditionally?

The name comes from stars of the Big Dipper. It carries no special category in the classical lists.

From traditional texts — not a claim of effect.
