Korean last name

KIM is a very common last name in Korea. If there are any Korean people around you, it is likely that his or her last name is also KIM. However, we are not related at all, as far as I know, I do not have relatives living here in the States whose last name is KIM. The name system in Korea is quite different from the one here as many other cultural things. There are only limited number of last names in Korea. There are some really rare ones, but we can recognize most of them as a Korean last name. In other words, it can not be something new or never heard. It works like first name does here. Most of American's first names are chosen from some popular ones such as John, David, Tom, Kathy, and Lori etc. Of course, last name can not be chosen by oneself. Fortunately, Korean first names are very various, you can invent them as you like (commonly with two words) and that is what Koreans do. So the combination of a (rather common) last name and a (rather unique) first name works well to identify an individual person. So does my name I believe.
