Chinese people placed great value in practice of kung-fu because it's a Holistic Martial Art training with Essence, Energy & Spirit as ONE which taught them disciplines, confidence, respect, patience, humility, morality and connection with nature/universe and everyone. It's excellent for complete overall health, fitness, balance and well-being. There is a reason for every move and every form. We can use kung-fu training to develop our awareness, consciousness & presence as meditation in motion/movement or as practical self-defense use ( absolutely ONLY last resort to use it for self-defense ) . Kung-Fu is a general term which includes hundreds of styles of Chinese martial arts. Each kung-fu style has soft ( Yin ) and hard ( Yang ) techniques. All styles of kung-fu contains both internal and external components as holistic training.
