Ok Let me go on record and say i dont know much about internal martial arts. I studied Taji mantis kung-fu and tan-tui system for about 6 1/2 years. i did some chi cultivating exercises but nothing specially since i didnt sign up for the tai-chi class offered. this video popped up in my youtube playlist and it looked super BS to me. seeing as ive seen tons of Martial artist fight of different generations, and skill levels. yet never seen anything like this.

So, is there any factual base to this? or is it just clever marketing.
