Perhaps you should try some spelling variations:
ersten things » ersten teils, ten things, unseen things
see things » set things, keep things, same things
yan sudan » kano sudan, yan guan, yan yuan
sudan der » suden der, sudan debt, sudan das
dong wei » wang wei, dong di, dong hoi
wang » wing, wan, 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 yan sudan der ((ersten things) OR (see things)) sharing ((dong sin) OR (dong wei)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan sudan der ((ersten things) or (see things)) sharing ((dong sin) or (dong wei)) ;*.
