Like most boys who grew up among the Mongol nomads of the early 13th Century, the young Gwok Jing was an avid wrestler. The problem was that he was never any good at it. As a child, he routinely had his butt handed to him by his peers in Mongolian wrestling. As a teenager, he wasn't much better: Prince Dosi of the Ongkhan Tribe beat the living tar out of Gwok Jing during their wrestling matches.
Years pass, and Gwok Jing masters numerous great Chinese martial arts. He becomes arguably the greatest martial artist in the world, but other than making his body much stronger, did that help his Mongolian wrestling skills any? During a later chapter of LOCH, Gwok Jing was able to use his Mongolian wrestling skills to surprise West Poison Au Yeung Fung. In ROCH, Gwok Jing used Mongolian wrestling skills to manhandle two Mongolian wrestlers who accosted him at Kublai Khan's base camp near Seung Yeung Fortress. Did Gwok Jing's wrestling skills actually somehow improve, or was he "cheating" by using his great Chinese martial arts skills?
