My first visit back to Hong Kong since the eighties and a lot had changed. Now part of China, there have been many cahnes but the most obvious was that it had become dirtier, with the footpaths full of rubbish in the mornings. There were many, many high rise buildings, especially for housing, right next to each other.
HKG has three main areas - THe Island, Tsim Sha Tsui and the New Territories, towards Mainland China.
