Perhaps you should try some spelling variations:
wang doing » wang daoping, wang yong, wang jing
best wrong » went wrong, been wrong, best bring
wrong john » wong john, strong john, kong john
yang lin » yang jin, wang lin, yang li
wong sam » wong sau, wong lai, kong sar
yang xi » yang di, yang yi, yang jui

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 xi)) best wrong john ((wong sam) OR (kong (sar OR sara))) ;~.
• Adding a wildcard symbol may retrieve word variants: wang doing ((yang lin) or (yang xi)) best wrong john ((wong sam) or (kong (sar or sara))) ;*.
