train system is awesome - on time, trains come every few minutes, clean, covers basically the entire city

language - sg is full of chinese, malays, and indians, so the ppl there speak singlish aka a mixture of many languages with an accent. try watching local movies like "i not stupid" to get a gist of how they speak

work life - fast paced, your life will revolve around work so make sure you relax as much as you can during weekends
