Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
sang minh » kang minah, anh minh, song min
tang min » chang min, yang mind, tang li
yang jin » yang jie, yang jun, ying jin
hong ghi » zhong zhi, hong g, hong hai
yang xi » yang di, yang yi, yang jui
xi hua » xie hua, li hua

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 yang xi hua (rene OR irene) ((((tang min) OR (sang minh))) OR (yang jin)) hong ghi ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang xi hua (rene or irene) ((((tang min) or (sang minh))) or (yang jin)) hong ghi ;*.
