Wong Yung's idea for Gwok Jing to fight as a proxy against East Heretic Wong Yerk See and North Beggar Hung 7 Gung in turn so that the two Greats would not need to risk injuring each other was praised as another brilliant idea, but was the idea a retread? It dawned on me that Wong Yung's idea was just a slight modification of the plan that Wong Yerk See had earlier in LOCH when he had Hung 7 Gung fight Au Yeung Hak and Gwok Jing fight West Poison Au Yeung Fung as proxies during the first of the betrothal contests on Peach Blossom Island. Wong Yung was just recycling her dad's idea with a slight modification.
