1Where is Chengshan?

Back of the calf, where the two gastrocnemius bellies join the calcaneal (Achilles) tendon.

Rising onto the toes brings out an inverted-V dip at the lower end of the muscle.

Beneath the point

Lateral head of gastrocnemius · Medial head of gastrocnemius · Calcaneal tendon · Soleus muscle

Our 3D measurement · In our 3D model: the top of the ∧ where the two gastrocnemius heads part, 8.6 cun below the knee crease.

2How do I find it on my body?

Stand and lift the heels, or lie face down and point the toes.
Watch where the bulge of the calf ends and its two heads part in an upside-down V.
Press the pointed dip just below the tip of that V, where muscle meets the calcaneal tendon.

📖 Words explained

lateral head of gastrocnemius: The outer of the two heads of gastrocnemius.
medial head of gastrocnemius: The inner of the two heads of gastrocnemius. It is bigger and reaches lower than the outer head.

3Before you press

⚠ Do not press when

If one calf is swollen, painful, red or warm, do not press — see a doctor (it may be a vein clot).
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?

The name means 'supporting the mountain' — the bulge of the calf. The Zhenjiu Jiayi Jing gives Yufu (fish belly) and Rouzhu as alternative names.

From traditional texts — not a claim of effect.
