Perhaps you should try some spelling variations:
ying john » king john, young john, ying jin
yang lin » yang jin, wang lin, yang li
wong sam » wong sau, wong lai, kong sar
bonn auf » bonn zur, bonn zum, bonn am
ku ying » ka ying, ku ring, hui ying
bonn a » bonn am, bonn _, bon a
wang » wing, wan, lang

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 yan ((yang lin) OR (yang di)) ku ying john ((((wong sam) OR (bonn a))) OR (bonn auf)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan ((yang lin) or (yang di)) ku ying john ((((wong sam) or (bonn a))) or (bonn auf)) ;*.
