i would say unless you know that you're going to get a nice big housing allowance that you know will get you comparable space to where you are coming from, leave your furniture at home... you may not have room for it here.
in one of your other posts, you mentioned that you are considering DB... if that's the case then there is ALWAYS stuff available second hand.
buy your electronics here, much less hassle than trying to buy converters/transformers for everything...
as for a car... .what do you mean? do you want to import your car?(a crazy idea, i think)
again, in DB there are no private cars allowed...besides, most people in hk do not have cars. the public transportation system is excellent and very cheap. i've been in hk for 11.5 years and have never owned a car. the only time i miss it is on weekends when i'd like to visit my aunt who lives clear across the territory... takes me 2.5 hours to get there from where i live. just not feasable to go and have lunch...
