1Where is Shuiquan?
Inner side of the foot, 1 B-cun straight below Taixi (KI3).
It is the hollow just in front of the calcaneal tuberosity.
Flexor retinaculum of ankle · Flexor digitorum longus · Posterior tibial veins · Posterior tibial artery
2How do I find it on my body?
- Find Taixi.
- The inner ankle peak to the sole counts as 3 B-cun, so drop straight down one third of that (1 B-cun).
- Press the hollow just in front of the rounded tuberosity of the heel bone.
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.
- flexor retinaculum of ankle
- A tough band from the inner ankle to the heel bone. The toe-bending tendons, the posterior tibial artery and the tibial nerve pass beneath it.
- 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.
- 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
- 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 Xi-cleft point of the Kidney meridian (Zhenjiu Jiayi Jing) — a historical classification, not a claim of effect.
- The name is usually translated as 'Water Spring'.
From traditional texts — not a claim of effect.

Chinese standard (2021) differs · China's 2021 standard describes it as the hollow on the inner side of the calcaneal tuberosity (WHO: in front of it).
