Perhaps you should try some spelling variations:
lang yang » wang yang, lang lang, ylang ylang
yang yang » wang yang, wang yan
best time » test time, next time, best true
past time » past five
chong suk » chong yun, cong sun, yong suk
hong suk » yong suk, hong seo, hong yu
yang ii » yang di, yang xi, yang yi

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 ii ((best time) OR (past time)) hong ((hong suk) OR (chong suk)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang yang yang ii ((best time) or (past time)) hong ((hong suk) OR (chong suk)) ;~".
• Adding a wildcard symbol may retrieve word variants: lang yang yang ii ((best time) or (past time)) hong ((hong suk) OR (chong suk)) ;*.
