I am not being funny but if you post it in a different language other than English then you will have few readers, only the ones who can understand your language will be able to read your hub. You will get less views, and less followers which means less money for you. As I said, I am not being funny, I am being realistic. I could write my hubs in my own language(Tagalog) but I know that only my fellow country people will understand and read it. I am not saying you can't, you can if you want to but not fair on others who does not know your language.
