Which BL point lies 1.5 cun lateral to the lower border of the spinous process of the fourth thoracic vertebra (T4)?

• A. BL-12
• B. BL-14
• C. BL-15
• D. BL-13

Answer: (D)

Back-Shu points on the Bladder channel follow a clear vertebral map: each thoracic level has a Shu point located about 1.5 cun lateral to the spinous process. In this sequence, the levels line up as T2 with BL-12, T3 with BL-13, T4 with BL-14, and T5 with BL-15. So a point at the lower border of the fourth thoracic vertebra corresponds to BL-14. The option listed as BL-13 would align with the third thoracic level, not the fourth. In standard charts, the correct match for T4 is BL-14.
