* I think it is a good idea for tourists. I have two reasons. First, it helps.
people speak easily. If they don't know the language of that country, they can't
ask how to get destination and can't order at the restaurant. It cause some
problem. But unless they use this language, their trip will be more
cheerful
Second, they can get the chance to talk with local people during the trip.
I think communicate with them will be great experience. They will teach us
about culture, history, and so on. It's so amazing!
