Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
wang das » wang dan, wang dashu, wang yan
hua rene » hua ren, juan rene
yang jui » yang judy, yang yi
wong sau » wong sam, wong siu, wong shiu
das ton » das tor, das toten, das tool
ton hua » tan hua, tong hui, dong hua
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: wang das ton hua rene ((((yang xi) OR (yang di))) OR (((yang yang) OR (yang jui)))) wong sau ;~.
• Adding a wildcard symbol may retrieve word variants: wang das ton hua rene ((((yang xi) or (yang di))) or (((yang yang) or (yang jui)))) wong sau ;*.
