I watched the video again and I think all the moves they are doing are used to do kicks, I mean if you watch clearly you can see that they have always one feet in a position like they want to kick someone and if you see
this video you see one of them having two swords so I think they really do this white lotus martial art... I really would like to see a battle of users of this martial art
When do you think people die?
When they are shot through the heart by the bullet of a pistol?
No.
When they are ravaged by an incurable disease?
No.
When they drink a soup made from a poisonous mushroom?
No!
It's when... they are forgotten.
