Most schools are marketed as places for self defence but some teachers think it is reserved more for individuals who have a greater ability to kill people more easily such as soldiers police, etc. What category does kung fu come under? Is it self defence or killing? Wu Shu means martial arts but kung fu is generally translated as "hard work". Wu shu may mean battlefield strategies but kung fu might mean self defence, which means you can practice even if you can't cut someone into two pieces. There seems to be more of a military traditon in Japan, but in China the main schools are associated with Shaolin, Wudang shan and Emei Shan. All are religious centres. My instructor, who is asian and quite good at martial arts, frowns on people who want learn martial arts, but can't kill people easily, and rejects them as cowards. Is this the general rule? He believes that if you cant kill another individual with a dear antler blade to the throat in mortal combat, you are weak, and a wasting your time. Is this common? They also believe that the warrior philosophy is to scald weak individuals when you meet them in day to day life, much like in feudal times.
