Perhaps you should try some spelling variations:
wang yuhan » wang luhang, wang yan, wang yidan
yang ping » yang jing, yang liang, yang using
ping wang » ping pong, hong wang
yang jui » yang judy, yang yi
eang hay » dang hai
kang han » kang chen, kong hang, zhang han
yang xi » yang yi

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: yang ping wang yuhan gain ((((yang jui) OR (yang di))) OR (yang xi)) ((eang hay) OR (kang han)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ping wang yuhan gain ((((yang jui) OR (yang di))) or (yang xi)) ((eang hay) or (kang han)) ;~".
• Adding a wildcard symbol may retrieve word variants: yang ping wang yuhan gain ((((yang jui) OR (yang di))) or (yang xi)) ((eang hay) or (kang han)) ;*.
