Perhaps you should try some spelling variations:
wang doing » wang daoping, wang yong, wang jing
wrong john » wong john, strong john, kong john
kong saur » kong sar, kong siu, kong your
yang lin » yang jin, wang lin, yang li
yang jui » yang judy, yang di, yang xi
wong sau » wong sam, wong siu, wong shiu

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 doing ((yang lin) OR (yang jui)) went wrong john ((wong sau) OR (kong saur)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang doing ((yang lin) or (yang jui)) went wrong john ((wong sau) or (kong saur)) ;*.
