Why are chinese dresses so rare in anime/manga?

How is your nationality represented in animu /a/?
Is it common to see it?
That ain't anime though and there aren't very many Mexicans in anime. KoF just has a ton of Mexicans compared to other fighting game series because SNK knows that Mexicans love KoF.
Luchadores are not an uncommon thing m8
There are many Mexicans in boxing anime, usually as the last bosses. Also countless luchadores. There's even a Mexican Gaogaigar in Gun x Sword
