Perhaps you should try some spelling variations:
wilke rene » wie rene
chang hsun » chang ch'un, chung hsuan, chang su
yan liang » yang liang, wang liang, you liang
yan clan » das clan, yan yuan
yan guan » gan guan, yan yuan, yang guang
yi chang » ii chang, ying chang, jin chang
yang yi » yang di, yang xi, yang jui
wang » wing, 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 OR wan) ((((yan clan) OR (yan liang))) OR (yan guan)) wilke rene yang yi chang hsun ;~.
• Adding a wildcard symbol may retrieve word variants: (wang or wan) ((((yan clan) or (yan liang))) or (yan guan)) wilke rene yang yi chang hsun ;*.
