Perhaps you should try some spelling variations:
hua irene » hua ren
kong john » king john, wong john, longo john
wang tan » wang yan, wang ban, wang tao
wang dan » wang yan, wang ban, wang yidan
wong sam » wong lai, von sam, wong max
wong sau » wong siu, wong shiu, wong lai
sar » sara, star, saur

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 ((wang tan) OR (wang dan)) hua irene kong john ((((wong sam) OR (wong sau))) OR (kong sar)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((wang tan) or (wang dan)) hua irene kong john ((((wong sam) OR (wong sau))) or (kong sar)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((wang tan) or (wang dan)) hua irene kong john ((((wong sam) OR (wong sau))) or (kong sar)) ;*.
