1Where is Xiajuxu?

It lies on the ST35–ST41 line, level with GB35 and GB36.

It is on the front of the lower leg.

Beneath the point

Tibialis anterior muscle · Tibia

Our 3D measurement · In our 3D model: on the ST35–ST41 line, 9 cun (207.4 mm; 1 lower-leg cun = 23.04 mm) below ST35, over the tibialis anterior.

2How do I find it on my body?

Find ST35 and ST41.
Split the line between them into 16 B-cun.
Go 9 down from ST35, which is 1 below ST38.

Check · on the line, over the tibialis anterior.

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
