Each of the Jin Yong heroes had a signature attack kung fu that he used for fighting. Kiu Fung and Gwok Jing favored the Hong Lung 18 Palms. Deun Yu used the 6 Mak Divine Swords, and Hui Juk had a potpourri of Siu Yiu Sect attack techniques. Yeung Gor used a variety of attack techniques before finally settling on Heavy Iron Sword Technique and the Sad Palms. Ling Wu Chung used Mt. Hua Sect Sword Technique and moved on to Dook Goo 9 Swords.
But what was Cheung Mo Gei's signature attack kung fu? His power came from the 9 Yeung Jen Ging, but that had no attack techniques in it. Keen Kwun Dai Loi Yee allowed Cheung Mo Gei to exploit his opponents' weaknesses, but that doesn't seem quite like an attack method either. Cheung Mo Gei learned Tai Chi Sword and Tai Chi Fist from Cheung 3 Fung, but other than the battle at Mo Dong, he did not subsequently use these skills in combat much either. There was the Divine Scepter martial arts of the Persian Ming Cult, but again, Cheung Mo Gei did not use this much. Just what was his attack martial art?
