Perhaps you should try some spelling variations:
kyoung yun » young yun, kyoung yang, hyoung gun
lang yang » wang yang, yang yang, ylang ylang
lang lang » ylang ylang
best true » best trade, best truth, best run
past time » past five
yun eun » young eun, jung eun
yang i » yang xi, yang yi, yang li

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((lang yang) OR (lang lang)) ((yang i) or (yang di)) ((best true) or (past time)) kyoung yun eun ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((lang yang) OR (lang lang)) ((yang i) OR (yang di)) ((best true) OR (past time)) kyoung yun eun ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((lang yang) OR (lang lang)) ((yang i) or (yang di)) ((best true) or (past time)) kyoung yun eun ;*".
