All weight is underside
If we can issue power with strong force but don't know the techniques to attack and defend, we can never defeat the opponent no matter how strong the power we can issue. On the contrary, if we only know the techniques of attack and defense but do not know the method of power issuing, we cannot defeat the opponent either no matter now many times we are able to hit the opponent. These two techniques are complementary and should be learned simultaneously. Adam Hsu
