In Kung fu, to start with we learn to respect the skill itself. We value our teacher and our other students. For if abused, the art could be lethal and we'd harm ourself as well as others. This respect comes from our value for our own selves. We don't wish to be injured by other people and as a result, we don't wish to harm other people. In connection with this, we have to avoid alcohol and drugs and its particular natural hazards.
