Perhaps you should try some spelling variations:
wang yang » wang yan, wang liang, wang yanling
yang yang » wang yan
his last » als last, his host, his land
doug bin » dort bin, org bin
dong bin » dong sin, dong di, dann bin
li last » i last, als last, die last
thing » things, think, thin

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