Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
hua rene » hua ren, juan rene
wang qin » wang qiao, wang jing, wang ning
wang lin » wang li, yang lin, wang limin
yu gang » xu gang, yi gang, yu fang
yang li » yang lin, yang di, yang xi
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 ((yu gang) or (yang yang)) hua rene ((((wang qin) OR (wang lin))) or (yang li)) peng sen ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: yang ((yu gang) OR (yang yang)) hua rene ((((wang qin) OR (wang lin))) OR (yang li)) peng sen ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "yang ((yu gang) or (yang yang)) hua rene ((((wang qin) OR (wang lin))) or (yang li)) peng sen ;*".
