A friend who writes about male frequency has been struggling with a question for me: about the identity of Aroben.

In Baidu Encyclopedia, Aroben is just a missionary who came to the Tang Dynasty from Persia. So, did Aroben have to be a native of Persia?

Of course not.

Aroben went from Persia to the Tang Dynasty more than a thousand years ago, so what about more than two thousand years ago? Where did she go to Persia again? That's a problem. Oops, the tablet can't write inspiration~
