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

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

Answer: (D)

Locating points on the Kidney channel uses precise distances and nearby landmarks on the medial leg. The described position places the point on the medial aspect of the lower leg, about two cun above the ankle point Taixi (KD-3), and just in front of a point higher up the leg (Fuliu, KD-7), while still behind the tibia. This exact spot corresponds to Kidney 8, which is situated on the medial leg between KD-3 and KD-7, just anterior to the tibia and posterior to the soft tissues. Thus the described description matches Kidney 8. The other options don’t fit these spatial relations along the medial leg and tibial border.
