1Where is Tongziliao?

Side of the face, in the hollow just outside the bony rim of the eye socket.

It is 0.5 B-cun outward from the outer corner of the eye.

Beneath the point

Zygomatic bone · Frontal bone · Orbital part of orbicularis oculi

Our 3D measurement · In our 3D model: skin 6.4 mm (0.5 cun; 1 head cun = 12.83 mm) lateral to the outer corner of the eye opening — almost exactly over the front edge of the lateral orbital rim at that height (0.7 mm outside it).

2How do I find it on my body?

Close the eyes and find the outer corner of the eye.
Slide a fingertip outward until it meets the bony edge of the eye socket.
Press the hollow just outside that edge.

Check · it is about 0.5 B-cun from the eye corner.

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

orbital part of orbicularis oculi: The outer ring of orbicularis oculi, lying on the bony rim of the eye socket. It works when you squeeze the eyes tightly shut.
zygomatic bone: The bone that sticks out on the cheek below and outside the eye. You feel it as a hard bump on the upper cheek, and it reaches back toward the ear to form the zygomatic arch with the temporal bone.
frontal bone: The skull bone that forms the forehead and brows. Its upper part is the forehead and its lower part makes the roof of the eye sockets.
