Recently the Grandmaster came over to the UK as part of the celebrations for Wu's Tai Chi Chuan Academy's 25 year anniversary, and he has written an introduction to the anniversary book.

The book is a real treasure trove of tai chi history, with many photographs and articles, a really interesting read! Not only that, but there are some real thought-provoking nuggets in there, which certainly got me thinking about various issues, to help me improve myself...

The book is available through http://www.wustyle-europe.com/shop.html 
Read and enjoy!
