There's a character difference between Big5 and English for Goo Gei Gwan.
I got the characters displayed on the English page on the credits of "Legend of the Dragon". So I think those on the Big5 page, are wrong.

Both are correct.

Then BOTH should be on BOTH sites, or not?

Sorry excuse my bad english. I meant actually both characters are the same. Their slight difference does not mean nothing.

You are right (perhaps a difference in fonts?), but it's a bit confusing, for those who don't know that they are the same, to see two "different" characters displayed, but I think not many will notice it.
