Perhaps you should try some spelling variations:
zhang yan » zhang fan, zhang jian, wang yan
irene han » irene a
wong shiu » cong shu, song shin, wong sau
yang jui » yang judy, yang yi
wong siu » kong siu, wong sau, wong siew
yang xi » yang yi
han min » han men, kan min, chan ming

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

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