During the third and final event in the betrothal contest on Peach Blossom Island, did anybody other than East Heretic Wong Yerk See and Chow Bak Tung know what it was that Gwok Jing and Au Yeung Hak were reciting (e.g. the 9 Yum Jen Ging)? I have a feeling that Au Yeung Fung knew what it was (or at least suspected), but possibly Wong Yung and Hung 7 Gung were in the dark about what the verses meant.
