This book may be said to be written in an easy to read autobiographical style and his main aim may be said to be to propose a cooperation between allopathic medicine and Qi Gong medicine. The author, Master Hong Liu, does this by means of an engaging narrative describing the way he came to know and learn Qi Gong therapy after he was already a Doctor in allopathic medicine in a military hospital of Sanghai.
Think there is a section introducing the Eight Brocade Exercises, with valuable and detailed descriptions and ilustrations of them, it might not be wise to relay just in this book to start learning them. So this book may not be considered a textbook to start learning Qi Gong, it is rather an introduction to a way of practicing medicine with case examples of it.
There is a section to introduce how to deal by means of exercises and herbal remedies some case examples, which include several diseases: AIDS, Allergies, Arthitris, Prostate Cancer, Headaches, Hypertension, Stress and Depression, Stroke and Weight Loss. Each of them is introduced with a story about an actual case treated by Master Hong Liu. Think one may try to practice the exercises which are proposed, it wan't be so easy to find the herbal remedies because they are from the chinese fitotherapy. You may not expect to learn how to heal these diseases just by reading this book.
Conclusion: Hong Liu's book may be read as if it were a novel of how Allopathic medicine and Qi Gong medicine meet in the life of Master Hong Liu. This book may be neither considered a textbook, nor a treaty on medicine, although some exercises and some chinese fitotherapy recipes are described.
