Always a fascinating theory, though never one that's been proven. If it did happen, it happened before Wong Seung invented the 9 Yum Jen Ging. In fact, the theory goes that because he tasted defeat at Dook Goo Kau Bai's hands, Wong Seung spent the next 40 years devising a way to defeat him (and others in the Ming Cult). The result was the 9 Yum Jen Ging. Unfortunately, by that time, all of Wong Seung's competition had died or disappeared.Originally Posted by Yeung Gor
