Xingyi is offensive... although it seems defensive, based on the
moves. Like Taiji, although it's a soft art, if you master it, it
can harm a person. Somebody in our group was injured when he didn't
control it well and hit another team mate too hard. Out of
commission for a few months. I was hit too, and no kidding.
Thankfully no bruises.
You've got to let Master Chong try Xingyi on you and tell me what's
pain. The pain felt is like the usual pain you feel when you fall.
But with a subtle difference. Not telling what that difference
is.
