Look, defending against "Wing Chun" really depends on the opponent and situation. But there are a lot of things CLF has at the disposal. Even more if the guy cross-train in another fighting style.
I am not worried about most Wing Chun people I fight. Only thing is if they are a lot bigger than me, which is a ****ing problem regardless of the style.
But Wing Chun usually not too many problems all things relatively equal.
It is bias to think that the art of war is just for killing people. It is not to kill people, it is to kill evil. It is a strategem to give life to many people by killing the evil of one person.
