Perhaps you should try some spelling variations:
seung yeon » jeong yeon, seung joon, seung youn
seung won » seung joon, seung youn, myung won
test kaw » test a, test kit, test awt
wan yan » wang yan, nan yan, wai yan
yang li » yang lin, yang di, tang li
yang yi » yang di, yang jui
yang xi » yang di, yang jui
kaw min » kyaw min, kan min, law main

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 li) or (((yang yi) or (yang xi)))) test kaw min ((seung yeon) OR (seung won)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: wan yan ((yang li) OR (((yang yi) OR (yang xi)))) test kaw min ((seung yeon) OR (seung won)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan ((yang li) or (((yang yi) or (yang xi)))) test kaw min ((seung yeon) OR (seung won)) ;*".
