All this talk of bad vibes is quite interesting but I do not think some people on this forum should be so negative about Hong Kong or its people. If you hate Hong Kong and you have the financial means, you can just leave. It might be better for you.
Someone mentioned people often stay here for money. Well if they are the ones moaning, it just reinforces the adage that money does not buy happiness!!
There are good and bad people everywhere.
I have seen Hong Kong people giving up their seats on the MTR and traffic trying to let ambulances and fire engines get through in congested streets. I have also witnessed injustice and stepped up to say so.
However, I have never witnessed young Hong Kong men attacking people for no reason but I certainly have seen British young men attacking people for no reason in Britain.
There are advantages and disadvantages to most things and places. I feel privileged to live in Hong Kong and I can go home to England whenever I want.
