For a person traveling in a country where they do not speak the same language, it is difficult to relay what you want to say or do. One major headache especially in China even for me, is ordering dishes in a restaurant. Not all restaurants have English menus and if they do, the translation doesn’t help. If you look at the picture I got from another website on the right, you will know what I mean.
A friend of mine experienced going to a restaurant where they have different prices for English and Chinese menus. He said if you can’t read the characters on their promos, you might miss something cheap.
