Dear Nga Ting:
Thanks for your prompt reply. I just got back from HK yesterday for a brief stay (1 week). Actually my first visit was 2 months ago. Though only stayed for 3 days but I was so impressed by how internationalization HK is and couldn`t help but visiting her again.
About the workers from Indonesia and Phillipine you mentioned, it seems that HK government is having a lawsuit about their legitimate right of staying in HK because of some Phillipine female workers fighting for their rights aiainst to HK court. (I can only guess some of the Cantonese they said..)
I`m Vegetarian and I thought it might be difficult for me to find places to eat in HK, but fortunately I searched OpenRice website beforehand and found some good restaurants. Some veggie food really amazed me because I never had eaten such yummy veggie food so far! It was really good.
