ooh! well, most of the jobs in Hong Kong require you to speak Chinese but I'm not sure if that applies to your field.
I wish I could land a job in that field...they all require previous experience which is something I lack for styling. Magazines here are released monthly and weekly (depends) and there are a TON of them. You have the regular Cosmo, Marie Claire (both in Chinese) and then you get some of the weekly ones; some for teens, some for a wider audience.
do u know which company you're interested in?
