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, le hong
yang yi » yang di, yang jui
yang xi » yang di, yang jui
irene a » irene m, sirene _
a xie » a die, a pie, a wie
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 tan ;~.
• Adding a wildcard symbol may retrieve word variants: ((dan data) or (wang yidan)) ((yang yi) or (yang xi)) irene a xie hong tan ;*.
