First-World Problem...

As time passes, I find I want more and more to pretend not to be an illiterate barbarian. I want to be able to say "安史之亂" rather than "that mid-eighth century Civil War that separates Great Tang from Later Tang" and "唐玄宗" and "安祿山" rather than "that silly besotted emperor" and "the rebel Sogdian general".

The problem is that I literally cannot hear the tones and the breathing. So I have no idea how to say "安史之亂", "唐玄宗", or "安祿山" correctly.

Can anything be done?
