"Birds do not fly above Beijing."
Translation:Peking fölött nem repülnek madarak.
However, on thinking about it, a comparable sentence would be ebben az erdőben emberek nem laknak. It's a general statement but we don't need "az emberek." Perhaps this isn't a general statement in the way that "pigs grunt" would be a general statement or, perhaps more relevant, "ostriches do not fly."
