Which GB point in the parietal region is 1.5 cun posterior to Zhèngyíng GB-17, along a curved line between Tóulínqì GB-15 and Fēngchí GB-20?

• A. GB 16
• B. GB 17
• C. GB 18
• D. GB 19

Answer: (C)

On the Gallbladder meridian, there is a curved scalp line through the parietal region that runs from Tóulínqì (GB-15) toward Fēngchí (GB-20). Along this line, the points appear in sequence as GB-16, GB-17, GB-18, GB-19 as you move posteriorly. Being 1.5 cun behind Zhengyíng (GB-17) places you at GB-18. This location sits on the parietal region along that curved line, making GB-18 the correct point.
