Perhaps you should try some spelling variations:
shown what » show what, known what, shome what
dan yang » daun yang, tan yang, wang yang
yao yang » yang yang
yi shown » _ shown, 15 shown, 21 shown
what tax » what can, flat tax, what a
cost van » cost land, cost vs, cost dam
cost a » cost _, cost 4, cost 5

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: wan ((dan yang) OR (yao yang)) yi shown what tax ((cost van) OR (cost a)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan ((dan yang) or (yao yang)) yi shown what tax ((cost van) OR (cost a)) ;~".
• Adding a wildcard symbol may retrieve word variants: wan ((dan yang) or (yao yang)) yi shown what tax ((cost van) OR (cost a)) ;*.
