Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
hua irene » hua ren
irene yan » irene a, ren yan
wang tan » wang yan, wang ban, wang dan
wang tao » wang qiao, huang tao, wang yan
hong ghi » zhong zhi, hong g
hong hai » shang hai, zhong tai, dang hai
yan jiu » yang jie, yang jin, pang jiu

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: yuan ((((wang tan) OR (wang tao))) OR (wang yang)) hua irene yan jiu ((hong ghi) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yuan ((((wang tan) OR (wang tao))) or (wang yang)) hua irene yan jiu ((hong ghi) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: yuan ((((wang tan) OR (wang tao))) or (wang yang)) hua irene yan jiu ((hong ghi) or (hong hai)) ;*.
