Perhaps you should try some spelling variations:
ying john » king john, young john, ying jin
wing ian » wing tan, twinn ian, wing sun
wong sau » wong sam, wong siu, wong shiu
yang li » yang lin, yang xi, yang yi
ku ying » ka ying, ku ring, hui ying
bonn am » bonn zum, bonn ana, bonn auf
bonn a » bonn _, bon a, bonn 1

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