Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing tan » sharing tags, sharing a, sharing bad
yan yang » yang yang, yao yang, dan yang
hong shu » tong shui, wong shiu, hong seo
wong yue » wang yue, hong yu
wan yan » wang yan, nan yan, wai yan
yang xi » yang di, yang yi, yang jui
xi cost » ii cost, di costo, die 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: wan yan yang xi cost sharing tan ((((hong shu) OR (cong shu))) OR (wong yue)) ;~.
• Adding a wildcard symbol may retrieve word variants: wan yan yang xi cost sharing tan ((((hong shu) or (cong shu))) or (wong yue)) ;*.
