I'm curious. There has never been a clear best kung fu. 9 Yang is better than 9 Yin internally; however it's weaker in terms of outer. Former world 1's Xian Tian Gong we have no statistics though it should be strong because from the way JY DESCRIBED (not said), South Monk had the strongest internal (note, this is after 1st Hua moutain). Then there's Dragon's 18 Palm, but Sad Palm rivals it. Then there's Shaolin's Jin gong jin (sorry, not sure how to directly translate it) or gold metal jin that has tons of great outer kung fu. There is also the west side QKDLY which is alwesome. Naturally according to book, 9 Yang, 9Yin, Demonic are suppose to be the strongest. 9 Yang for internal. 9 Yin mainly for outer matched with top part. Demonic, I guess just pure unstoppable power. So what you guys think?
