Chinese acrobats

I really like this kind of acrobatic! I love the jump inside of hand to hand.
But i'm a bit sad, because i saw a lot of circus contemporary show, and nobody do or maybe thought, something like this. I think its really interessing way.They researched so much.
A lot of people said: "chinese doing just crazy technic", im not sure about this. In this dvd from 1959 i saw a really interessing stuff.
I'd really like to see in some comtemporay show this kind of acrobatic, o something similar. Or maybe these level its really high, i dont know.
