The Name Jar
The Name Jar, by Yansook Choi, explains that you should be proud of your name and heritage. Unhei is the main character. She wants to pick a "normal" name that is not Korean. However, she doesn't feel like many other names suit her. So, her class mates put name suggestions in a jar so that she could pick what she wanted to be called. In the end, she realized that her name is beautiful and that she should be proud of it.
