Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
hua rene » hua ren, juan rene
yang nie » yang di, yang xi, yang yi
yang jie » yang jin, yang di, yang jui
yi gang » ii gang, i gang, li gang
yu yang » du yang, yi yang, yu fang
sen » seen, sein, send

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: yang ((((yi gang) or (yu yang))) or (wang yang)) hua rene ((yang nie) OR (yang jie)) peng sen ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: yang ((((yi gang) OR (yu yang))) OR (wang yang)) hua rene ((yang nie) OR (yang jie)) peng sen ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ((((yi gang) or (yu yang))) or (wang yang)) hua rene ((yang nie) OR (yang jie)) peng sen ;*".
