Perhaps you should try some spelling variations:
wang liang » wang yang
wang wang » wang yang, wang yan, wang jing
wang yong » wang yang, wang hyoung, wang yan
hua irene » hua ren
ying john » king john, young john, ying jin
john wong » john song, john bonn
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 wang) OR (wang yong))) OR (wang liang)) wang hua irene ying john wong sau ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((wang wang) OR (wang yong))) or (wang liang)) wang hua irene ying john wong sau ;~".
• Adding a wildcard symbol may retrieve word variants: ((((wang wang) OR (wang yong))) or (wang liang)) wang hua irene ying john wong sau ;*.
