Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
yang yang » wang yang, wang yan
sharing a » sharing _
tong shui » tong hui, cong shu, gong hui
yan yang » yao yang, dan yang, tan yang
yi cost » ii cost, di costo, die cost
hong yu » wong yue

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 ((yan yang) OR (yang yang)) yi cost sharing a ((tong shui) OR (hong yu)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan ((yan yang) or (yang yang)) yi cost sharing a ((tong shui) or (hong yu)) ;*.
