Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang yang » wang yan
his last » his host, his land, its last
als last » als gast, a last, its last
dong bin » dong sin, dong di, dann bin
org bin » dort bin
thing » think, thin
things » thinks, thins

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 yang yang ((his last) OR (als last)) (thing OR things) zeng ((org bin) OR (dong bin)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang yang ((his last) or (als last)) (thing or things) zeng ((org bin) or (dong bin)) ;*.
