If we use the analogy that all Wrestling styles are Bows, we have compound bows, composite bows, re-curve bows, long bows and cross bows. We know each is based upon improvements to the technology, all essentially perform the same task, but have a special purpose that the improvements were used to address. So lets say Composite Bow=Boke, Re-curve Bow = Shuai Jiao, Long Bow = Sumo, Composite Bow = Judo and Compound Bow= BJJ. Then we can definitively say that each style thereafter, that focuses on the specific aspects of the principles of compound, composite, re-curve etc. is based upon that particular improvement to the technology and all are based upon that of stick and cord. Wouldn't this analogy hold true for arts like Yong Chun? If Yong Chun is Compound Bow, couldn't all arts that are based upon Compound Bow principles really be the same thing, just decorated differently? Even with addition of silencers, sights etc. to improve the use of the technology, do these additions change the basic principles of Compound Bow?
