SushiLover, no need to get so defensive, it was merely a suggestion. Nowhere did I suggest that you don't donate money to charity.
I'm not sure if you have noticed that the gap between the poor and the rich is quite wide here, and that many people who are getting the $6000 are the ones who don't really need it (or are spending it on holidays or a new iPad). Many charities are encouraging people to donate their $6000 to help that who need it most.
While your family may have lived in HK for several generations (I will be the fifth generation to be here), it sounds like you personally left at a young age and probably did not pay any taxes. Whilst I think it is OK for your parents and grandparents to receive the money, I think you need to think of others who live in a place where the welfare system is maybe not as good as the one you come from.
Finally, you do not pay tax on bank accounts. You don't even pay tax on the interest you earn.
