Traditional martial arts (like ours) contain very efficient and deadly techniques. These techniques originate from a past in which these kind of techniques were used for survival and combat purposes (= Self-defense). However, times have changed.
In our 'civilized' society, everything is bound by rules and laws. These laws are used by the government to uphold an ordered society, but also to manipulate our lives. Official laws decide what is allowed and what is not. Because there are so many laws and the complicated way they are formulated, most people do not fully comprehend them.
In our society we are confronted by the abuse of violence towards ourself and others. Through serious study of kungfu, we are able to eliminate violence towards us. In the past it was easy: one killed one's attackers. Nowadays, self-defense is bound by law.
