Perhaps you should try some spelling variations:
irene mah » irene m, irene a
siew hong » siew keong, siew kheng, sek hong
dan dana » dan data, mann dana, dan doa
wang dan » wang yan, wang ban, wang yidan
wang hui » wang hua, wang zhi, wang wei
yang jui » yang judy, yang di, yang xi
hong vu » hoang vu, hong yu, hong tou

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: ((dan dana) OR (wang dan)) ((wang hui) OR (yang jui)) irene mah siew hong vu ;~.
• Adding a wildcard symbol may retrieve word variants: ((dan dana) or (wang dan)) ((wang hui) or (yang jui)) irene mah siew hong vu ;*.
