Which point is on the medial side of the lower leg, 3 cun inferior to Yīnlíngquán SP-9, in a depression just posterior to the medial crest of the tibia?

• A. SP 9
• B. SP 7
• C. SP 6
• D. SP 8

Answer: (D)

This question tests precise point location along the spleen channel using leg landmarks and a standard measurement. From Yinlingquán (SP-9) on the medial side of the lower leg, moving 3 cun inferior along the channel brings you to a depression that lies just posterior to the medial crest of the tibia. That exact spot is SP-8, also known as Diji. SP-8 is the point described by this combination of being on the medial leg, 3 cun below SP-9, in a depression behind the tibial crest. It’s used to invigorate blood and regulate issues like menstrual disorders and abdominal pain due to blood stasis.
