Which point is described as being 0.5 cun directly posterior to Quchai?

• A. BL 2
• B. BL 3
• C. BL 4
• D. BL 1

Answer: (D)

Understanding this item comes from knowing precise point locations along the Bladder channel around the eye. Quchai is a landmark near the eye, and the point described as 0.5 cun directly posterior to it is Bladder 1, located at the inner canthus. This position makes Bladder 1 the closest point to that landmark on the Bladder line near the eye, whereas the other points are situated higher on the brow/forehead region (medial eyebrow area and beyond) and do not fit the description of being 0.5 cun behind Quchai.
