Perhaps you should try some spelling variations:
wang yang » wang liang, wang yanling
hua irene » hua ren
yang hua » wang hua, yang hui, ying hua
yang jie » yang jin, yang di, yang xi
yang jui » yang judy, yang di, yang xi
wong sam » wong sau, wong lai, kong sar
won sau » wong sau, wong siu

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: ((wang yang) or (wang yan)) yang hua irene ((yang jie) OR (yang jui)) ((won sau) or (wong sam)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (wang yan)) yang hua irene ((yang jie) OR (yang jui)) ((won sau) OR (wong sam)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (wang yan)) yang hua irene ((yang jie) OR (yang jui)) ((won sau) or (wong sam)) ;".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (wang yan)) yang hua irene ((yang jie) OR (yang jui)) ((won sau) or (wong sam)) ;*.
