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

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

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