Which point is 5 cun above the prominence of the medial malleolus, immediately posterior to the medial crest of the tibia, in the depression between the medial crest of the tibia and the gastrocnemius muscle?

• A. LV4
• B. LV2
• C. GB41
• D. GB43

Answer: (A)

This item tests precise point location along the Liver channel on the medial lower leg. The described site—five cun above the prominent medial ankle, just behind the tibial crest, in the hollow between the tibial crest and the gastrocnemius—matches a medial-lower-leg point on the Liver channel. The point located there is Liver 4, a primary point often used to move Liver qi and regulate smooth flow in the lower body.

Think of how the Liver channel runs up the medial leg from the big toe. Located in this medial-lower-leg hollow, a five-cun distance above the ankle aligns with Liver 4. This point is chosen specifically for its effect on Liver qi stagnation and its ability to influence structures in the lower abdomen, pelvis, and legs.

The other options lie in different regions: they are on the dorsum of the foot or on the lateral side of the foot, not in the described medial-lower-leg hollow, so they don’t fit the landmarks given in the question.
