Seriously don't miss this if you do the Cheng Man Ching 37 posture "short form" of Tai Chi. This was filmed when he was younger and more sprightly than in some of the previously-seen footage that is out there, and this is the best Tai Chi we have seen him do. It also shows some delightful aspects of his character as he walks down to the area where he does his form, and there's some push hands and martial applications at the end for good measure! The video is not on YouTube; it's on the website of the Shen Long Tai Chi Association UK, to whom we are very grateful:
