Jiu Yang Shen Gong's theory of martial art ressemble more of Wudang(the REAL ONE). One of the theory of Jiu Yang Shen Gong is move after the opponent move.Originally Posted by Yun_Feiyang
Wudang Sword's theory said there is no fix rule to attack or fight(like the formless theory). It would move based on the reaction of the opponent, so it would move afterward. Both theory of course would reach the opponent first, although attacking last. The only different between Wudang and Jiu Yang Shen Gong, is wudang is based on TaiChi/BaGua the idea of changes. So when a wudang practicer attacks, it continuous changes in direction and everything. When it changes it hit the target(this one resemble the Abbot of Shaolin in SOD). Not sure if Jiu Yang Shen Gong have any theory on this though since it wasn't mention.
