I was checking out Zhou's WTA profile which didn't have her picture updated. Only this was shown as you can also see in many other not-so-famous players:
I used to think that's just a random sketch but no, a name came to me, I put it up into the search bar, and yes that's her.
Okay this may be stupid but I do feel kinda proud of myself.
Come on just have some fun and give a guess.
