Perhaps you should try some spelling variations:
wang yidan » wang yan
kang minah » sang minh
yang muxi » yang hui, yang mu
song minh » sang minh, song min, song ming
yang jui » yang judy, yang di, yang yi
cong sun » cong shu, cong van, wing sun
yang xi » yang di, 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: wang yidan ((((yang muxi) OR (yang jui))) OR (yang xi)) a ((song minh) OR (kang minah)) cong sun ;~.
• Adding a wildcard symbol may retrieve word variants: wang yidan ((((yang muxi) or (yang jui))) or (yang xi)) a ((song minh) or (kang minah)) cong sun ;*.
