1Where is Fuliu?

Back-inner side of the lower leg, 2 B-cun above the peak of the inner ankle bone.

It lies just in front of the Achilles tendon; Jiaoxin (KI8) is at the same height, further forward.

Beneath the point

Posterior tibial veins · Posterior tibial artery · Calcaneal tendon · Flexor digitorum longus

Our 3D measurement · In our 3D model: 2 cun (46.0 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), just in front of the Achilles tendon. It is 19.4 mm (0.84 cun) from KI8 (WHO: 0.5 cun) — still to be verified.

2How do I find it on my body?

Use the inner-leg scale: from the lower edge of the tibia's medial condyle (SP9) to the inner ankle peak is 13 B-cun.
Go up 2 B-cun from the ankle peak.
At that height, press just in front of the front edge of the Achilles tendon.

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

flexor digitorum longus: A muscle that starts deep on the inner back of the calf, curves behind the inner ankle and attaches to the tip bones of the 2nd–5th toes. It bends the toes.
medial condyle: The inner rounded knob at the lower end of the femur or the upper end of the tibia. Below the inner knee, the lower edge of the tibia's medial condyle catches under your fingertip.
posterior tibial artery: The artery running deep down the back of the calf, behind the inner ankle and into the sole. You can feel its pulse in the hollow between the inner ankle and the Achilles tendon.
posterior tibial veins: The veins running deep in the back of the calf alongside the posterior tibial artery.

3Before you press

⚠ Do not press when

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 Jing-river (Metal) point of the Kidney meridian — a historical classification, not a claim of effect.
The name joins fu (to return) and liu (to flow) — usually translated as 'Returning Current'.

From traditional texts — not a claim of effect.
