Although I have practiced Chen-style Taiji for several years, I did not learn Taiji Push-Hand.
From last month, I began to learn Push-Hand with Yang-style Taiji teachers. Their teaching also changed my feeling that Yang-style Taiji is eaiser than Chen-style. With good teachers around, I am confident that I can improve my health and Taiji skills from now on. :)
There are some good videos about Chen-style and Yang-style Taiji here. I save the link in this post for my later reference.
