Perhaps you should try some spelling variations:
shawn thanh » phan thanh
wang shawn » tan shawn
kind john » king john, hinde john, und john
kong saur » kong sar, kong siu, kong your
thanh vu » thanh van, thanh _
vu irene » _ irene
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 shawn thanh vu irene kind john ((((wong sau) OR (wong lai))) OR (kong saur)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang shawn thanh vu irene kind john ((((wong sau) or (wong lai))) or (kong saur)) ;*.
