Hong Kong is the best place on Earth
The only drawbacks are the hot weather in the summer and the high cost of living. Otherwise, it's the best. Just go and find out.
Insider Tip:The first thing you should do is buy an Octopus card (八达通) - you can use this to pay for many things and is preferable to carrying around cash. Except for food and housing, prices on most things are negotiable so be prepared to haggle. I'd suggest taking the public buses around Kowloon and HK Island as a comfortable and inexpensive way to see the city (sit upstairs). Try to learn a few Cantonese phrases before going - this isn't really necessary, but people appreciate the effort.
