Which point is 4.3 cun inferior to Dàhéng SP-15?

• A. SP 11
• B. SP 12
• C. SP 13
• D. SP 10

Answer: (B)

The test is about the vertical relationships along the spleen meridian on the abdomen. SP-15 (Dàhéng) is located on the abdomen, 4 cun lateral to the midline and level with the umbilicus. Moving downward along that same vertical line, the next spleen point in this region is SP-12, which sits in the inguinal area and is about 4.3 cun below SP-15. Therefore SP-12 is the point described as 4.3 cun inferior to SP-15.

The other options are at different locations either higher up toward the umbilicus or in other areas (for example, SP-10 is on the thigh), so they don’t match the specified vertical distance from SP-15.
