This book is a required text for my "Fundamentals of Chinese Medicine" class which is part of a Master's Degree Program in Acupuncture, at Pacific College of Oriental Medicine. The book is very good, but it's not easy to read. It is densely packed with information. You really have to sit and think about each paragraph and consider the meanings implied. There are substantial footnotes at the bottom of almost every page which does help one decipher the text. Good luck to all taking on the challenge of learning Chinese Medicine!
