Perhaps you should try some spelling variations:
qian yan » qian jun, qian yi
hua wang » hwa wang, hua jiang, yuan wang
yang jie » yang jin, yang di, yang xi
yang jui » yang judy, yang di, yang xi
wong sau » wong sam, wong shiu, wong lai
wong siu » wong shiu, kong siu, wong siew
yan yan » yan yuan, nan yan, yang yang

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: wing ((yan yan) OR (qian yan)) hua wang ((yang jie) OR (yang jui)) ((wong sau) OR (wong siu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wing ((yan yan) or (qian yan)) hua wang ((yang jie) OR (yang jui)) ((wong sau) or (wong siu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wing ((yan yan) or (qian yan)) hua wang ((yang jie) OR (yang jui)) ((wong sau) or (wong siu)) ;*.
