If you are interested in Chinese medicine and so on massage techniques (do in) or another (shiatsu), buy this book eyes closed. The condensed theory of Chinese medicine of the first part is very well done (nice summary table to scan and enlarge). Sure, it's light and we can be satisfied with what is proposed. It is the same with the party do in. This is why I recommend buying this book to complement other more extensive books. Considering the price, you do not ruin you! "The secret of Chinese self-massage" provides very useful information as "self-massage Express" you will not find elsewhere. But to do in the indispensable book is "Do in" Jean Rofidal.
