Perhaps you should try some spelling variations:
wang ying » wang yang, wang yong, wang ning
wang jing » wang ning, wang liang, wang yang
hua rene » hua ren, juan rene
yang jin » yang jie, ying jin, shang jin
yang jun » yang jui, pang jun, yang judy
yan jiu » yang jie, pang jiu
hong ng » hong kong, hong jong, hong hong

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 ((wang ying) OR (wang jing)) hua rene ((yan jiu) OR (((yang jin) OR (yang jun)))) hong ng ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((wang ying) OR (wang jing)) hua rene ((yan jiu) or (((yang jin) or (yang jun)))) hong ng ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((wang ying) OR (wang jing)) hua rene ((yan jiu) or (((yang jin) or (yang jun)))) hong ng ;*.
