I personally took this picture a few years ago on campus. Once you start looking for multilingual signs in public spaces, you become addictive. My students told me that they could never walk down the street again the same way as before as they were very conscious of the various languages used in various places. This one was an advertisement for learning Chinese. I liked the use of Australian expression translated into Chinese. Obviously this was designed to attract Australian English speaker kids who come from Chinese background. I wonder if you see such advertisements in your area where you live. which languages?
