A few questions about the martial arts level of various (non-Greats) ROCH characters, and one about Yeung Gor's martial arts from the middle of ROCH.
First, Fung Mak Fung -- the student of East Heretic Wong Yerk See. When he first appeared in ROCH, he had a confrontation with Lee Mok Sau. Fung barely won that fight, and only by the virtue that his weapon (a superheated walking stick) was better than Lee Mok Sau's duster. Later in ROCH, however, Fung Mak Fung gave his life to rescue Gwok Jing and Yeung Gor from the Golden Wheel Monk, Siu Seung Tze, and Lui Mor Singh. Although the three Mongol mercenaries eventually killed him, Fung put up one hell of a fight...managing to hold the three mercenaries at bay until Yeung Gor could get Gwok Jing to safety. How did he do it? If Fung Mak Fung was slightly better than Lee Mok Sau, then at best, he was probably at the same level as either Siu Seung Tze or Lui Mor Singh individually. The Golden Wheel Monk was a Greats-level fighter; he should have trounced Fung easily all by himself. For about a minute, however, Fung held all three mercenaries off almost as well as Gwok Jing did. How could he have done that?
The Mo Brothers: They had a duel against each other that didn't prove anything. Were the two brothers really evenly matched, or did one have an edge over the other?
Yeung Gor: how good were his martial arts skills at the time of Gwok Jing's fight against the Mongol mercenaries? How did Yeung Gor stack up against Wan Hak Sai, Siu Seung Tze, and Lui Mor Singh at that point?
