Perhaps you should try some spelling variations:
things were » things here, things we, things work
dong sind » dong sin, dong bin, dong ping
wang den » wang dewen, wang peng, zwang der
wang dan » wang yan, wang ban, wang yidan
dann bin » dong bin
4 smart » a smart
gang 4 » gang 3, gang _, yang 4

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 den) OR (wang dan)) gang 4 smart things were ((dann bin) OR (dong sind)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang den) OR (wang dan)) gang 4 smart things were ((dann bin) or (dong sind)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang den) OR (wang dan)) gang 4 smart things were ((dann bin) or (dong sind)) ;*.
