During ROCH, it was not exactly a secret among Gwok Jing's elders and contemporaries that during his youth, Gwok Jing was a prince consort of the Mongol Empire and one of the key generals in its military forces. Were his children (Gwok Fu, Gwok Seung, and Gwok Por Lo) and students (the Mo Brothers) aware of this fact, however? I'm under the impression that among the kids, only Yeung Gor knew about Gwok Jing's past affiliations with the Mongols.
