Perhaps you should try some spelling variations:
wang yidan » wang yan
irene mah » irene m, irene a
dan dana » dan data, mann dana, dan doa
wang dan » wang yan, wang ban, wang yang
yang hui » yang jui, wang hui, yang muxi
wang yue » wong yue, wang yan, wang he
mah xie » mah siew

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

• Performing a fuzzy search may retrieve terms with similar spellings: ((dan dana) or (((wang dan) OR (wang yidan)))) yang hui irene mah xie ((wang yue) or (wang hua)) ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((dan dana) OR (((wang dan) OR (wang yidan)))) yang hui irene mah xie ((wang yue) OR (wang hua)) ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dan dana) or (((wang dan) OR (wang yidan)))) yang hui irene mah xie ((wang yue) or (wang hua)) ;*".
