This book got short shrift in our education even though we bought in in the first year or two.It is essential for its coverage of auricular and scalp acupuncture (not to mention other imaging styles such as "nose acupuncture"). It also has a slightly different view of channel pathology symptoms from "Chinese Acupuncture and Moxibustion" (CAM) or "Foundations of Chinese Medicine."
The way they organize the body points (by regions of the body and commonality of usage), however, is too counter-intuitive to be useful in practice.
In fact, I think that Deadman's Manual of Acupuncture would make a much better body point reference than Shanghai, CAM, or Foundations... Deadman's book is entirely based on the classics and cites its sources.
They really should put out a new edition of Shanghai with better body point organization.
But, for the student and practitioner, this is a gem.
