Perhaps you should try some spelling variations:
yang yang » wang yang, wang yan
sudan der » suden der, sudan debt, sudan das
kong hong » hong hong, kong hang, kong heng
yang jui » yang xi, yang yi
era kong » era among
3 sudan » _ sudan, im sudan, _ sudano
der era » der erb, der erde
tan » than

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: ((((((yang judy) OR (yang jui))) OR (yang yang))) OR (yang di))a 3 sudan der era kong hong tan ;~.
• Adding a wildcard symbol may retrieve word variants: ((((((yang judy) or (yang jui))) or (yang yang))) or (yang di))a 3 sudan der era kong hong tan ;*.
