Perhaps you should try some spelling variations:
wang yidan » wang yan
yang muxi » yang xi, yang hui, yang mu
irene mah » irene m, irene a
wang dan » wang yan, wang ban, wang yang
yang jui » yang judy, yang di, yang xi
xie hong » kia hong, tin hong, min hong
le hong » law hong, sek hong

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: ((wang dan) OR (wang yidan)) ((yang muxi) OR (yang jui)) irene mah ((xie hong) OR (le hong)) tou ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang dan) or (wang yidan)) ((yang muxi) or (yang jui)) irene mah ((xie hong) OR (le hong)) tou ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang dan) or (wang yidan)) ((yang muxi) or (yang jui)) irene mah ((xie hong) OR (le hong)) tou ;*.
