I think these names refer to one and the same person. At least that's what it says in this article: http://www.kungfucinema.com/first-look- ... lades-9560

Also, the images below of both look like it's one and the same person (despite the different time periods in each of the images). Even their Mandarin names, apart from the numbers 1 and 2 in the parenthesizes respectively, match.

Interesting... I never recognized him. I think you're right though, they should be merged.

if nobody stops me in 15 days I will merge them
