In the old days in mainland China the kung fu fighters fought bare handed and were unafraid to do so, because they knew exactly how to pulverize an opponent with thunderous machine gun like blows without breaking their own hands It took me a whole lot of trouble and effort to get this first dvd on the market for you. Until recently this specialized knowledge was only kept within the Chi Sim Kung Fu family. Therefore it took me literally weeks of continue trying to convince master Sergio Iadarola and even longer to convince his teacher grandmaster Cheng Kwong to make this knowledge available on a worldwide scale so people like you can be a part of this amazing knowledge from the southern shaolin temple.
