During the terrific five-day international workshop in Helmond, 67 participants played, experienced and felt the extension, contraction, weight-shifting and elasticity in every move of the set. Andrew Hung clarified that these elements are the source, better known as the don-yu and the tor-yu. When we started with the first set at the beginning of the workshop it was obvious that we were discounting the moves. As the workshop progressed we learned how to apply the source clearly in the set by practising small parts diligently. The result was that the set lasted longer and longer. “Tai chi is not slow, but you have more to do”, Andrew Hung mentioned.
