In Korea, many people have two names - a family name and a given name. Your family name is like your last name, and it tells people which family or clan you belong to. There are only a few hundred family names in Korea, so many people have the same family name. For example, the most common family name is Kim. If your family name is Kim, it means you are part of the Kim clan.
Your given name is the name your parents choose for you when you are born. This is what people usually call you by. In Korea, given names can have different meanings, and parents often choose names based on the meaning. For example, the name Ji-yoon means "wisdom" and "success."
Sometimes, people also have nicknames or other names that they go by. These can be based on their personality, their interests, or their job.
Overall, names in Korea are important because they tell you about a person's family background and sometimes even their personality. So next time you meet someone from Korea, pay attention to their name - it might tell you a lot about them!
