Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing tan » sharing tags, sharing a, sharing bad
wang yang » wang yan, wang liang, wang yanling
yang yang » wang yan
wang hui » wang hua, wang wei, wang he
yang ka » yang fan, yang yao
ka cost » a cost, can cost, car cost

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 ka cost sharing tan ((tong hui) OR (((wang hui) OR (wang zhi)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang yang ka cost sharing tan ((tong hui) or (((wang hui) OR (wang zhi)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang yang ka cost sharing tan ((tong hui) or (((wang hui) OR (wang zhi)))) ;*.
