Language is one of the most difficult things foreigners face in another country. In general thoughts, all the animals including people have their own language to communicate with others. Therefore, if we don’t know the language of that country, we can’t communicate with the local people. (Perhaps someone will say, “Why don’t we use body language?” Yes, it is sure that most of the body language is globalized around the world but there are still some exceptions, like the action “ok” means “money” in Japanese) not relevant. As a result, we can know that if we can’t communicate with the locals briefly, we can’t get what we want so we may not enjoy the trip or feel disappointed to it. Besides, it will become a lot of misunderstandings while we don’t know the language clearly too. Sometimes, it will even produce different problems or quarrels or may also put us to a dangerous way.
