Amazingly, there's a rumor that Voicemith (Xia Yu Yao's company) was supposed to make her a VOCALOID, but got rejected by YAMAHA since Facio/GYNOID beat them to the punch and got Xin Hua.

So they banged out Xia, which is why she's so buggy because they can't oto. Which is why producers have a hard time using her.
