Perhaps you should try some spelling variations:
kyoung yun » young yun, kyoung yang, hyoung gun
lang yang » wang yang, yang yang, lang lang
best true » best trade, best truth, best run
test time » next time, past time, cost time
best time » next time, past time, best type
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.

• If you are trying to use Boolean operators, they must be ALL CAPS: lang yang ((yang i) OR (yang di)) ((best true) OR (((test time) OR (best time)))) kyoung yun eun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yang ((yang i) or (yang di)) ((best true) or (((test time) OR (best time)))) kyoung yun eun ;~".
• Adding a wildcard symbol may retrieve word variants: lang yang ((yang i) or (yang di)) ((best true) or (((test time) OR (best time)))) kyoung yun eun ;*.
