Wang Zhangjun demos applied Chen Taiji in an easy, step-by-step "learn it at home" style. I think Taiji (and IMA as a whole) are poorly suited to these 1-2-3 demos, as there is no sense of intercepting, sticking, following, leading, flowing, but such are the constraints of the media. As is, I think, typical of the current village style, the strong points are the throws and locks; the response to striking is - well, you be the judge.
