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 tao » wang qiao, huang tao, wang yan
hong ghi » zhong zhi, hong hai
yan jiu » yang jie, yang jin, pang jiu
hong g » hong ng, hong w, hong 7

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