First and foremost i want to apologize for people being offended by the Chinaman name. However, my reasoning for this is to be tongue in cheek in the way superhero names are given. You know how they put something in front of the word "-man" like Batman, Superman, Aquaman, etc. So, to draw some parallels, I used China-man for Yao Ming to parallel Superman for Dwight Howard. It was meant to sound like a superhero battle. Hopefully you can understand that, those who were offended.
