Perhaps you should try some spelling variations:
truong tran » truong thanh, truong xuan, tung tran
joon chang » hoong chang, boon chong, jin chang
chang kyun » chang yun, chang hsun, chang jiyoun
jai joon » ha joon
kyun pin » kyung min, yun hin
yang jui » yang judy, yang xi
yang li » yang lin, yang xi, tang li
yang yi » yang xi

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: jai joon chang kyun pin ((((((yang li) OR (yang yi))) OR (yang jui))) OR (yang di)) truong tran ;~.
• Adding a wildcard symbol may retrieve word variants: jai joon chang kyun pin ((((((yang li) or (yang yi))) or (yang jui))) or (yang di)) truong tran ;*.
