Perhaps you should try some spelling variations:
wilke rene » wie rene
yan liang » yang liang, wang liang, you liang
you lead » you leap, you ready, you need
yang yun » yang jun, tang yun, yang yue
yang jin » yang jun, ying jin, shang jin
yang jie » yang di, yang jui, yang xi
hong yu » wong yue

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: wan ((yan liang) OR (you lead)) wilke rene ((yang yun) OR (((yang jin) OR (yang jie)))) hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yan liang) or (you lead)) wilke rene ((yang yun) or (((yang jin) OR (yang jie)))) hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: wan ((yan liang) or (you lead)) wilke rene ((yang yun) or (((yang jin) OR (yang jie)))) hong yu ;*.
