We decided to stay in Jejudo (Jeju Island) for a year so we registered to the government office and changed our address. We are now residents in Jeju. We decided to become a residents of the island because we can save much for the entrance fees and insurance. People here pays less tax and insurance and there are much discounts for admission fees. Not to mention that most of them are free for Jeju residents.
Living in Jeju is not bad at all but it's hard that people here have their own dialects that even my husband who is Korean can't understand their talking. There are lots of differences between living in the city and the island. I also notice that people in Jeju don't throw their garbage well.
