Ohh and to go to DB from Hung Hom you can either take 115 to central ferry pier and ferry to DB or take E23 to Tung Chung walk around 10 mins take bus to DB. That also depends where in Hung Hom your work is. Both of the above are from Whampoa Garden. So if you are away from this area you will also have to consider the time you will take to get to Whampoa Garden.
