Which point lies 1 cun inferior to Taixi KID-3 in a depression anterior and superior to the calcaneal tuberosity?

• A. KD 5
• B. KD 3
• C. BL 66
• D. KD 8

Answer: (A)

The location is determined by following the Kidney channel from Taixi (the main point at the medial ankle) downward toward the sole and identifying the small depression about 1 cun below it. This depression is on the medial aspect of the foot, in front of (anterior to) and a bit above (superior to) the calcaneal tuberosity. That exact spot corresponds to Shui Quan, Kidney 5. It’s the next point along the Kidney channel after Taixi, positioned specifically in that depression just above the heel bone.

Other options are different points along the leg or on other channels, so they don’t match this precise depression’s location.
