Gwok Jing's original martial arts teachers, the Gong Nam 7 Freaks, were known to use a variety of unusual melee weapons. Ohr Jen Ngok used a combination staff/spear. Chu Chung used an ironclad fan. Hon Bo Kui used a horsewhip. Nam Hei Yan used some sort of lever. Cheung Ah Sang (who never got to teach Gwok Jing because he was killed off on the night of the day he met the boy) used a butcher's knife, and Cheun Gum Fat used a weights scale. Only Hon Siu Ying used a conventional sword.
Does this mean that Gwok Jing became an expert at using various unusual weapon types such as fans, horsewhips, levers and scales? We never see Gwok Jing ever use such weapons during LOCH and ROCH. Even before Gwok Jing met North Beggar Hung 7 Gung and made Hong Lung 18 Palms his default martial arts technique, he still fought barehanded (something his Freaks teachers didn't customarily do). How is it that these experts of unusual weapon types train a student who primarily fought unarmed?
