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 » pang jun, yang jin, yang judy
yang jui » yang judy, yang di, yang yi
chen yue » chen yu, chen yun, chen yulu
yang xi » yang di, yang yi
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 jui) OR (yang xi)))) chen yue ;~.
• 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 jui) OR (yang xi)))) chen yue ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yan guan) or (yan clan)) wilke rene ((yang jun) or (((yang jui) OR (yang xi)))) chen yue ;*.
