Singapore Changi Airport

Official Languages: English, Malay, Mandarin, Tamil

English Is the Working Language of Government, Business, Signage and Schooling, so You Will Never Need Another. Malay Is the National Language, Used for the Anthem and Ceremony, and Mandarin and Tamil Are the Other Two. Among Themselves Locals Speak Singlish, Which Is English at a Different Rhythm
