Apparently, the are:
Pay: HK$120k pcm
Annual bonus HK$40K
Joining bonus HK150K
And that's it. Don't know about leave.
It may sound good compared to home, but it won't go far in HK. Epsecially considering the KH English Schools Foundation (Governemnrt English language schools) have just announced that parents have to pay a HK$500K non returnable debenture per child for admission.
