Although it is not true, Koreans believe that they have maintained their ethnic purity for a long time. They speak a single language, Korean, in their teritory, as well as they look similar in their looks, having black hair and bright brown skin. However, things have been changed after rapid industrialization with increasing number of foreign workers in Korea. One of huge categories of foreigners in Korea is 'brides' from abroad, mostly from south asia. They are mostly married males who live in countrysides, since most Korean women are tend to not marry the males in rural area. Because the brides and their childs have difference in culture and looks, a lot of discriminations happens, unfortunately. Despite the efforts have been made by the government, it would take years to overcome this problem and to achieve cultural diversity.
