The fates of East Heretic Wong Yerk See's students Luk Sing Fung, Kuk Ling Fung, Mo Min Fung, and Fung Mak Fung leaves a few unanswered questions, especially since they were all crippled by their teacher.
1. How did they get off Peach Blossom Island? The crippled students were unable to walk. How were they able to procure transportation to get off the island?
2. Luk Sing Fung eventually became a wealthy and powerful leader of an anti-Jin (and later, anti-Mongol) force in TaiWu. Kuk Ling Fung owned his own inn in Ox Village, where he was a neighbor of Yeung Teet Sum and Gwok Siu Teen. These activities, especially those of Luk Sing Fung's, require money. How did Luk and Kuk get this money? I'm sure Wong Yerk See didn't provide them with a stipend before banishing them, and with their legs crippled, they were in no position to steal it or hire themselves out as mercenary fighters for it. This is especially perplexing in the case of Luk Sing Fung, who had a son and must have therefore have had a wife. What woman would marry a crippled man in those days unless he was wealthy?
3. Whatever happened to Mo Min Fung? We know he died like the rest of his former martial brothers, but under what circumstances? What did he accomplish before he died?
4. Why did these four students of Wong Yerk See not stay together after being banished from the island? Given that they were all crippled, their chances of survival would probably be higher if they stayed together than if they went their separate ways. And again, how did four crippled men get so far geographically separated from each other?
