Perhaps you should try some spelling variations:
lang yan » wang yan, wang yang, zhang yan
yan clan » das clan, yan guan, yan yuan
yang jui » yang judy, yang yi
yang xi » yang yi
won sau » wong sau, wong sam, wong siu
clan a » plan a, clan _, alan a
a gene » a genre, a gender, a gentle
lai » laid

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 yan clan a gene ((((yang jui) OR (yang xi))) OR (yang di)) ((won sau) OR (wong lai)) ;~.
• Adding a wildcard symbol may retrieve word variants: lang yan clan a gene ((((yang jui) or (yang xi))) or (yang di)) ((won sau) or (wong lai)) ;*.
