Perhaps you should try some spelling variations:
wilke rene » wie rene
yan guan » gan guan, yan yuan, yang guang
yan clan » das clan, yan yuan
yang jun » yang jui, yang judy, yang fan
yang jin » yang jie, ying jin, shang jin
pang jun » yang jui
chen yun » chen yu, chen yue, chen yiqun
wang » wing, wan, lang

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 ((yan guan) OR (yan clan)) wilke rene ((((yang jun) OR (yang jin))) OR (pang jun)) chen yun ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yan guan) or (yan clan)) wilke rene ((((yang jun) OR (yang jin))) or (pang jun)) chen yun ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan guan) or (yan clan)) wilke rene ((((yang jun) OR (yang jin))) or (pang jun)) chen yun ;*.
