Which point is on the medial aspect of the lower leg, 2 cun superior to Taixi KID-3 and 0.5 cun anterior to Fùliú KID-7, posterior to the medial border of the tibia?

• A. KD 7
• B. KD 6
• C. KD 5
• D. KD 8

Answer: (D)

This question tests precise point location on the Kidney channel using clear anatomic landmarks and distances. The described spot is on the medial side of the lower leg, 2 cun above Taixi (KD-3) and 0.5 cun anterior to Fùliú (KD-7), and it sits posterior to the medial border of the tibia. That combination of being a bit higher up from the ankle, slightly in front of the posterior border of the tibia, yet still along the inner edge of the leg fits the known position of KD-8. KD-7 lies on the posterior border of the tibia about 2 cun above the medial malleolus, so KD-8 is located just anterior to that point along the same medial line, still posterior to the tibia. Recognizing this spatial relationship makes the described location KD-8.

KD-7 is lower on the leg at the posterior border, KD-3 is at the ankle, and the other options don’t align with the described distances and relative position to the tibia.
