Hi, Mi [이름]. Actually, there are lot of ways on how you can greet me or even anyone else. You may say, "nice to hear from you again", especially if we haven't met for quite a long time. Or you may say "Hello, good evening too", "I'm so glad to hear from you", "Hello, teacher! pleasant evening to you"!! or you may even ask "how do you do?".
