1Where is Ligou?

On the front-inner leg, in the middle of the flat inner surface of the tibia.

It is 5 B-cun above the peak of the medial malleolus (inner ankle bone).

Beneath the point

Great saphenous vein · Tibia

Our 3D measurement · In our 3D model: 5 cun (115.0 mm) above the peak of the medial malleolus (1 cun = 23.00 mm, from the lower border of the medial tibial condyle to the malleolus = 13 cun), on the middle of the flat inner surface of the tibia (27.1 mm wide), level with KI9.

2How do I find it on my body?

Treat the distance from the apex of the patella (lower tip of the kneecap) to the peak of the inner ankle bone as 15 B-cun.
One third of the way up from the ankle is 5 B-cun.
At that height, press the middle of the flat inner surface of the tibia.

Check · it is level with KI9 (Zhubin).

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

great saphenous vein: A vein under the skin that starts on the inner top of the foot, passes in front of the inner ankle and climbs the inner leg to the groin. It is the longest vein in the body.
medial malleolus: The bump on the inner side of the ankle, the lower end of the tibia. Its highest point is a starting mark for measuring lower-leg points.

3Before you press

⚠ Do not press when

The skin over the tibia is thin, so press gently.
Avoid broken or swollen skin and press only to a comfortable level.
Acupressure is not a substitute for medical care.

4How has it been used traditionally?

Classified as the Luo-connecting point of the Liver meridian; the Lingshu (ch. 10) says a branch leaves here for the Gallbladder (Foot Shaoyang) channel — a historical classification, not a claim of effect.

From traditional texts — not a claim of effect.
