Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
zhang yan » zhang fan, zhang jian, wang yan
sharing a » sharing _
yan yang » yang yang, yao yang, dan yang
yang yue » yang yun, yang jui, yang yi
yue cost » true cost, type cost, use cost
wang yue » wang hua, wang yan, wang he

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang yan yang yue cost sharing a ((((wong yue) OR (wang yue))) OR (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: zhang yan yang yue cost sharing a ((((wong yue) OR (wang yue))) OR (hong yu)) ;*.
