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