Which point is located 1.5 cun proximal to H-7?

H-7, also known as Shenmen, is a point located at the wrist, on the ulnar side of the flexor carpi ulnaris tendon. In acupuncture point location, the cun measurement system is used, which helps locate points based on the patient's anatomy rather than fixed distances.

When identifying the point that is located 1.5 cun proximal to H-7, it’s essential to understand how the Heart channel (which includes the Heart points) is organized and where the subsequent points are placed relative to each other.

The points H-4, H-5, and H-6 are all located between H-7 and H-8 along the Heart channel. Specifically, moving from H-7 towards the elbow (proximal direction), H-4 is first and is located 1.5 cun above H-7. Therefore, H-4 is the answer that fits the criteria of being both proximal and at the appropriate distance from H-7.

In contrast, H-5 appears nearer than 1.5 cun away, while H-6 is slightly further along the channel than H-4. H-8 is located distally from H-7, making it an inappropriate choice for
