Perhaps you should try some spelling variations:
wang yidan » wang yan
wang ban » wang yan, wang dan, wang yang
yang jui » yang judy, yang di, yang xi
kang min » kan min, tang min, kang minah
min wong » min hong, minh cong, amin hong
wong sam » wong sau, wong lai, kong sar
yang li » yang lin, yang di, yang xi
lu kang » wu kang

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 ban) OR (wang yidan)) ((yang li) OR (yang jui)) lu kang min wong sam ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang ban) or (wang yidan)) ((yang li) or (yang jui)) lu kang min wong sam ;*.
