On the lower abdomen, 0.7 cun superior and 0.5 cun lateral to Chōngmén SP-12, 4 cun lateral to the midline. This point is also defined as lying 4.3 cun inferior to Dàhéng SP-15.

• A. SP 12
• B. SP 13
• C. SP 11
• D. SP 9

Answer: (A)

The main idea here is matching the described spatial coordinates to the known locations of Spleen channel points in the lower abdomen. The description places the point on the lower abdomen, about 4 cun from the midline. That specific horizontal offset from the midline corresponds to the classic position of Chongmen, SP-12, which sits in the groin area along the Spleen channel.

The statement that the point lies roughly 4.3 cun below SP-15 (Da Heng) helps confirm the vertical placement, since SP-15 is at the umbilical region and SP-12 sits well below it in the lower abdomen. Together, these clues point to SP-12 as the intended point.

SP-12 is the only option whose location aligns with being 4 cun lateral to the midline in the lower abdomen and in the groin region. The other points are located at different heights or areas: they do not share this exact abdominal position, with SP-9 being on the leg and the others occupying nearby but distinct spots along the abdomen.
