Perhaps you should try some spelling variations:
wang yidan » wang yan
dan data » can data, dan dana, dn data
xie hong » kia hong, tin hong, min hong
yang yi » yang di, yang jui
yang xi » yang di, yang jui
irene a » irene m, sirene _
le hong » law hong, sek hong
tan » than

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