Perhaps you should try some spelling variations:
chan ming » kian ming, chan eng, chan fong
wong siu » wong shiu, wong sau, wong siew
kong siu » kong eiu, dong sin, kong sar
wan yan » wang yan, nan yan, wai yan
yang li » yang lin, yang di, yang yi
yang xi » yang di, yang yi, yang jui
wu chan » w chan, wu chao, mun chan

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 yan ((yang li) OR (yang xi)) wu chan ming ((((wong siu) OR (kong siu))) OR (cong shu)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan ((yang li) or (yang xi)) wu chan ming ((((wong siu) or (kong siu))) or (cong shu)) ;*.
