Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
wan yang » wang yang, dan yang, awam yang
tan yang » dan yang, tan ying, tan yong
xi irene » _ irene, i rene, ii rene
yang tan » yang fan, liang tan, tang tang
wong sau » wong sam, wong siu, wong shiu
yang xi » yang di, yang yi, yang jui

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: ((wan yang) OR (tan yang)) yang xi irene ((((yang tan) OR (yang yang))) OR (yang dean)) wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wan yang) or (tan yang)) yang xi irene ((((yang tan) OR (yang yang))) or (yang dean)) wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((wan yang) or (tan yang)) yang xi irene ((((yang tan) OR (yang yang))) or (yang dean)) wong sau ;*.
