Master Wang Chieh, Push Hands Practice, Taiwan

I saw this intriguing photo on Flickr (I have a feed looking at photos with the "Tai Chi" tag) which then led me to this clip of a blindingly brilliant push hands session. This got everyone in the office wondering what was going on. Strength through softness, innit?

Mike Martello (reasonably well known in European/US/Taiwan Tai Chi circles), who put up the YouTube vid, along with dozens of others, seemed to be at the event (looks like it was organised by this club) photographed by Flickr user BeijingKungfuCamp2007.
