Perhaps you should try some spelling variations:
jeong yeon » jeong hyeok, jeang yean, jeong dahyeon
seung yeon » seung joon, seung won, seung youn
test awt » test auf, test a
wan yan » wang yan, nan yan, wai yan
yang ai » yang di, yang yi, yang dali
yang li » yang lin, yang di, yang yi
yang xi » yang di, yang yi, yang jui

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

• Performing a fuzzy search may retrieve terms with similar spellings: wan yan ((((yang ai) or (yang li))) or (yang xi)) test awt kin ((jeong yeon) OR (seung yeon)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan ((((yang ai) OR (yang li))) OR (yang xi)) test awt kin ((jeong yeon) OR (seung yeon)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((((yang ai) or (yang li))) or (yang xi)) test awt kin ((jeong yeon) OR (seung yeon)) ;*".
