Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
das ferne » das lernen, das berner, das eherne
chin hong » china hong, chin chang, china long
das clan » das bilan, das land, das cern
hsu chin » hsu bin, hsu shi
tan wong » tan hong, tan kong, tan yong
wong yue » wang yue, hong yu

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: lang ((((das clan) OR (das ferne))) OR (yang yang)) hsu chin hong tan wong yue ;~.
• Adding a wildcard symbol may retrieve word variants: lang ((((das clan) or (das ferne))) or (yang yang)) hsu chin hong tan wong yue ;*.
