FAQ

1Where is Tiaokou?

8 B-cun below ST35, the midpoint of the ST35–ST41 line.

It is over the tibialis anterior, level with ST40.

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, 8 cun (184.3 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.
Take 8 from ST35, the midpoint of the line.

Check · ST40 lies one finger-width further out at the same level.

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

tibialis anterior: The thick muscle running down the front of the shin, just outside the tibia. Lift the top of your foot and it hardens on the front of the shin, with a thick tendon standing out at the inner front of the ankle.
