. I have a concern that if there is a defense against someone who knows Chinese kung fu. My main concern is in Chinese kung fu they have rapid, machine gun type punches, that another Kung Fu master could quickly deflect by rapidly using your palm and twisting your waist left to right repeated deflecting all the punches. .
you have been watching Ip Man movies haven't you? the way to deal a kungfu master in the street, don't know what street there would be a kungfu master loitering around to pick fight, but if there is such a street, then the best defend against such master is either whip out your cell phone and call the police, or invite him/her/it into the local pub, out of the street, and duel over a few pints.
get off the fence and take up something, anything. old sailor saying "if no destination in mind, any direction would do".
