Besides getting your documentation ready.
One thing I would do, is scan all those local food recipe books
into a portable hardrive.
If possible, send your photographs for scanning and keeping into
the portable hard drive too. Same with whatever documents you
have.
And bring the portable hard drive along!
And for heavens sake, convert all your hokkien, chinese,
teochew, hindi, melayu CDs and DVDs into your hard drive and
mp3!
Then take time to go to Beach Road Army market, get yourself
some americanised dog tags to wear on body, buy some army kit bags
aka parachute bags and pack it into your luggage. Eat the
tulang, eat the local food there too.
Got your International Driving Permit? Got your
CNCC?
Cancelled your mobile phone and internet subscription yet?
Then call up all your long lost family and friends, go makan, go
drink kopi with them and exchange as much email
addy, messenger ids and facebook addies and telephone
numbers as possible.
Bring your camera and take lots and lots of pictures. You
can sort them out later when you are in another country.
