Which BL point lies 7 cun directly above BL60 and lateral to BL57?

• A. BL 58
• B. BL 56
• C. BL 60
• D. BL 57

Answer: (C)

On the Bladder channel, distances are measured along the leg from the ankle upward. BL60 sits at the lateral malleolus. About seven cun above that point is BL58 (Feiyang), which lies on the posterior calf slightly to the lateral side of the BL60 line and is distinct from BL57, which sits higher up the calf. Therefore, the point that matches being seven cun above BL60 and lateral to the BL60 pathway is BL58. The given key naming BL60 itself does not fit this spatial relationship, as BL60 is the anchor at the ankle, not the point seven cun above it.
