1Where is Yangfu?

Outer (fibular) side of the lower leg, 4 B-cun above the peak of the outer ankle bone, just in front of the fibula.

Beneath the point

Fibula · Extensor digitorum longus · Fibularis tertius muscle · Extensor hallucis longus

Our 3D measurement · In our 3D model: skin just in front of the fibula, 4 cun above the prominence of the lateral malleolus (1 cun on the lateral leg = 23.04 mm).

2How do I find it on my body?

Outer-leg scale: outer end of the knee crease to the outer ankle peak = 16 B-cun.
Go up 4 B-cun from the ankle peak.
At that height, press just in front of the fibula's front edge.

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

extensor digitorum longus: A muscle running from the outer front of the shin across the top of the foot to the 2nd–5th toes. Lift your toes and four tendons fan out on the top of the foot.
fibularis tertius: A small muscle running from the lower outer front of the shin to the fifth metatarsal; some people lack it. 'Third' here is part of the name, not a count.

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 (Fire) point of the Gallbladder meridian — a historical classification, not a claim of effect.
Fu (輔) refers to 'fugu', the classical name for the fibula; the character first named a brace that supports a cart wheel.

From traditional texts — not a claim of effect.

5Classical text

Donguibogam (Heo Jun, 1613), Acupuncture and Moxibustion, "Yangfu"

在足外踝上四寸輔骨前絶骨端如前三分去丘墟七寸足少陽脈之所行爲經 …《銅人》

4 cun above the outer ankle bone, in front of the "assisting bone"; about 3 fen forward of the end of the "severed bone" and 7 cun from Qiuxu. Where the Foot Shaoyang channel travels, which makes it the Jing-river point (Tongren Shuxue Zhenjiu Tujing).

Source tag as given in the Donguibogam: Tongren = Tongren Shuxue Zhenjiu Tujing.
The same wording is found in the Zhenjiu Jiayi Jing (vol.
3).
The garbled glyph 嚹 in the Wikisource text has been corrected to 踝 (ankle).
The "assisting bone" (fugu) here is an old name for the fibula; the "severed bone" (juegu) is an old name for the lower fibula, also an alternative name of GB39.
"…" marks the needling depth and moxa count, left out because they are for licensed practitioners.
