Perhaps you should try some spelling variations:
lang lang » ylang ylang
china who » china why, china what, china won
kong sara » kong sar
lang can » lung can, lang a
yang jui » yang judy, yang di, yang yi
wong sam » wong lai, kong sar, von sam
wong sau » wong siu, wong shiu, wong lai
yang xi » yang di, 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 lang can china who ((yang jui) OR (yang xi)) ((((wong sam) OR (wong sau))) OR (kong sara)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang lang can china who ((yang jui) or (yang xi)) ((((wong sam) or (wong sau))) or (kong sara)) ;*.
