Perhaps you should try some spelling variations:
gunning jan » dunning john
huang jing » huang ting, huang ying, wang jing
jing yang » jing fang, ying yang, wang yang
kong john » king john, wong john, longo john
ioki als » ki als, wiki als
wong sam » wong sau, kong sar, von sam
lai » laid

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: huang jing yang ioki als ((gunning jan) OR (kong john)) ((wong sam) OR (wong lai)) ;~.
• Adding a wildcard symbol may retrieve word variants: huang jing yang ioki als ((gunning jan) or (kong john)) ((wong sam) or (wong lai)) ;*.
