1Where is Lougu?

6 B-cun above the prominence of the medial malleolus, just behind the inner edge of the shinbone.

It lies 3 B-cun above SP6.

It is on the inner (tibial) side of the lower leg.

Beneath the point

Soleus muscle · Flexor digitorum longus · Posterior tibial veins

Our 3D measurement · In our 3D model: 6 cun (138.0 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 behind the medial border of the tibia (3 cun above SP6).

2How do I find it on my body?

Find SP6.
Take SP9 to the medial malleolus as 13 B-cun.
Go up 3 B-cun more, 6 from the malleolus.

Check · just behind the inner edge of the shinbone.

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.
posterior tibial veins: The veins running deep in the back of the calf alongside the posterior tibial artery.
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.
