Perhaps you should try some spelling variations:
wilke rene » wie rene
yan liang » yang liang, wang liang, you liang
you mean » you can, you eat, you lead
yang yun » yang jun, yang yue, yang yang
tang yun » chang yun, fang yuan, tang chun
yang jin » yang jie, yang jun, ying jin
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 mean)) wilke rene ((((yang yun) OR (tang yun))) OR (yang jin)) hong yu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((yan liang) or (you mean)) wilke rene ((((yang yun) OR (tang yun))) or (yang jin)) hong yu ;~".
• Adding a wildcard symbol may retrieve word variants: wan ((yan liang) or (you mean)) wilke rene ((((yang yun) OR (tang yun))) or (yang jin)) hong yu ;*.
