I thought Cantonese was mainly spoken in Hong Kong

Yes indeed. I'll check as soon as Kaisheng gets in about relative numbers of speakers. He's from Taiwan and does not speak Cantonese. Siu-ling in chorus speaks both so I could ask her too. Not sure where she's from right off hand.

Ænigma wants him to be Kajar and her to be Siva. Siva I know but who's Kajar?
