Which BL point is 1.5 cun inferior to BL60?

• A. BL 60
• B. BL 62
• C. BL 61
• D. BL 63

Answer: (C)

Distances along a meridian are measured in cun, guiding you to where each point sits on that channel. BL60 sits in the ankle depression, and moving 1.5 cun in the inferior direction along the bladder channel brings you to BL61. That exact positional relationship is why BL61 is the correct choice. The bladder channel continues down the leg toward the foot with points spaced by these small cun distances, so this particular 1.5-cun step downward lands at BL61. The other points lie at different positions along the channel or at different distances from BL60, so they don’t match the specified location.
