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
wong sam » wong lai, kong sar, von sam
wong sau » wong siu, wong shiu, wong lai
yang ji » yang jui, yang jie, yang jin
won 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 ji ((((won sau) OR (wong sam))) or (wong sau)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang yang) OR (wang yan)) yang hua irene yang ji ((((won sau) OR (wong sam))) OR (wong sau)) ;.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yang) or (wang yan)) yang hua irene yang ji ((((won sau) OR (wong sam))) or (wong sau)) ;".
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (wang yan)) yang hua irene yang ji ((((won sau) OR (wong sam))) or (wong sau)) ;*.
