Which BL point is on the lower leg, 7 cun directly superior to BL60, lateral to and approximately 1 cun inferior to BL57?

• A. BL 56
• B. BL 57
• C. BL 58
• D. BL 59

Answer: (C)

Locating bladder points on the lower leg relies on exact cun measurements and proximity to nearby landmarks. Start at BL60 at the outer ankle and move straight up the leg along the channel for seven cun. The point you reach, which lies lateral to BL57 and about one cun below it, is BL58. That specific relationship—7 cun above BL60 and just to the side and slightly below BL57—identifies the correct point. The other options sit in different locations along the calf and do not match this exact arrangement.
