I am sorry, but the man in those clips has VERY LITTLE skill at all, he is sloppy, not controlled, ... just plain awful?
This is not 'Shaolin' AT ALL.
OK, THE RULE ON NOT PUTTING DOWN ANOTHER STYLE.
I am not insulting this STYLE OF KUNG FU, I am SAYING THIS IS NOT KUNG FU. It may be a martial art, but it is NOT shaolin kung fu, nor does it look related to shaolin kung fu. It looks like a japanese martial art, with Chinese weapons, or 'imitated' Chinese movements.
I have studied Hung Gar kung fu for many years, and have started studyin Wing Chun kung fu. I have also two really close friends who both came from China (exchange students), and we practiced kung fu together, I have learned 2 northern shaolin forms from them. They seem authentic, though there is no way to be sure, but the exchange of kung fu was fun.
Anyway, like I was saying the whole SHaolin-Do thing...
It is NOT and I will repeat NOT kung fu.
(and if the guy in the clip is a seniour student of this Sin The guy, then it does not say a lot about Sin The)
