Perhaps you should try some spelling variations:
lang hyoung » wang hyoung, kang young, hwang byoung
seung yeon » jeong yeon, seung joon, seung won
min seung » min jeong
test kan » test a, test kit, test ke
yang xi » yang jui
yang yi » yang jui
kan min » han min, kian ming, kyaw min

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

• Performing a fuzzy search may retrieve terms with similar spellings: lang hyoung ((yang di) or (((yang xi) OR (yang yi)))) test kan min seung yeon ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: lang hyoung ((yang di) OR (((yang xi) OR (yang yi)))) test kan min seung yeon ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang hyoung ((yang di) or (((yang xi) OR (yang yi)))) test kan min seung yeon ;*".
