Perhaps you should try some spelling variations:
ying john » king john, young john, ying jin
wing ian » wing tan, twinn ian, wing sun
yang jui » yang judy, yang di, yang xi
wong siu » wong shiu, kong siu, wong sau
bonn zum » bonn zur
yang li » yang lin, yang di, yang xi
ku ying » ka ying, ku ring, hui ying
bonn a » bonn am, bonn _, bon a

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 ian ((yang li) OR (yang jui)) ku ying john ((((wong siu) OR (bonn a))) OR (bonn zum)) ;~.
• Adding a wildcard symbol may retrieve word variants: wing ian ((yang li) or (yang jui)) ku ying john ((((wong siu) or (bonn a))) or (bonn zum)) ;*.
