Only if this were ancient China and the girl is a virgin. Anyone touching a girl in the breast would cause the girl to faint from shock since that act would be considered scandalous and inappropriate behavior back then ; P

Maybe if you hit them in the heart and make it stop or explode it.

In the movies yes.

Let's see...

You poke them in the middle of their sternum like you are trying to squish a bug.... not likely. It's about as likely as leaping between the Bamboo trees thirty feet off the ground like later on in the clip, or like in almost every other "Woo Tang" martial arts movie.

Its possible.
