Hong Kong at night is one of the most amazing time and places to be. Public transport and the retail/leisure industry keep going until late evening which means it’s easy to get around. With vast amounts being invested into the tourism sector (e.g. the famous Symphony of Lights show which runs daily at 8pm) there’s always plenty to see and do. It’s also a very safe place to walk around with expensive camera equipment which means more time and effort spent on photography and less on worrying about being robbed.
