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
hong suk » chong suk, yong suk, hong seo
cong sun » cong shu, cong van, wing sun
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 (cong sun)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang yang yang ii ((best time) or (past time)) hong ((hong suk) or (cong sun)) ;*.
