In wuxia fiction, there were a few characters who, owing to their heritage, potentially could have been central characters in a wuxia story...if only they hadn't perished during childhood. Two who come to mind are Chow Lim Tung, the illegitimate son of Chow Bak Tung and Ying Goo, and the original Tse Mo Gei, biological son of Golden Haired Lion King Tse Tsun and namesake for Cheung Mo Gei, the protagonist of HSDS.
Both Chow Lim Tung and Tse Mo Gei were slain when they were infants, so it's impossible to know what kind of men they might have grown up to be. What do you imagine they would have been like, however?
Also, what other wuxia characters were killed during childhood before we could see what kind of adults they'd be like?
