Perhaps you should try some spelling variations:
things zeng » things zhang, things end, things using
yang yang » wang yang, wang yan
ran yang » dan yang, ran ying, tan yang
his coat » his host
his cows » his own
doug bin » dong bin, dort bin
org bin » dong bin, dort bin
dort ii » dort bin, dort hin

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: ran yang yang ((his coat) OR (his cows)) things zeng ((doug bin) OR (((org bin) OR (dort ii)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ran yang yang ((his coat) OR (his cows)) things zeng ((doug bin) or (((org bin) or (dort ii)))) ;~".
• Adding a wildcard symbol may retrieve word variants: ran yang yang ((his coat) OR (his cows)) things zeng ((doug bin) or (((org bin) or (dort ii)))) ;*.
