Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang john » young john, king john, yang jin
wong shiu » wong siu, cong shu, song shin
yong yan » yang yang, dong yang, ying yang
ren yang » ren yan, chen yang, dan yang
wong sau » wong siu, wong lai, kong sar
wong sam » wong lai, kong sar, von sam
hua ren » hua chen

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 ((yong yan) OR (wang yang)) hua ren yang john ((((wong sau) OR (wong shiu))) OR (wong sam)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yong yan) or (wang yang)) hua ren yang john ((((wong sau) OR (wong shiu))) or (wong sam)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yong yan) or (wang yang)) hua ren yang john ((((wong sau) OR (wong shiu))) or (wong sam)) ;*.
