There's a difference between Feng Huang and phoenix? Besdies translation?
If there is, then Feng Huang are the true phoenixes just like Gyarados, not Kairyu, is a true dragon.
Fun fact: Ho-oh's official Chinese name is actually Feng Huang. no joke. EDIT: It's obvious but, Ho Ou, as the user above just stated, is really just the way of saying Feng Huang in JP. --- -User Name Origin: http://www.youtube.com/watch?v=tO_5esMq2kE#t=56s "Japanese Wii U.
