This little site has information about Tai Chi, the classes in Hove that I teach and a blog. I see no point in reproducing what you can find elsewhere on the web so I have included a page of links to relevant sites.
Cheng Kam-yan son of Cheng Tin-hung
Jonathan posted on the FaceBook group that he had recently had the pleasure of training with Cheng Tinhung’s youngest son in Hong Kong. Some really good video of various Wudang tuishou/pushing hands. In fixed step free-style Jonathan got a couple of draws but didn’t score once so said he ‘must train harder’ an attitude I respect!
