Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
zhang yan » zhang fan, zhang jian, wang yan
yan yang » yang yang, yao yang, dan yang
yang yun » yang jun, tang yun, yang yue
yun cost » run cost, can cost, eu cost
a wang » _ wang, x wang, hwa wang
l wang » li wang, _ wang, x wang

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 yun cost sharing ((a wang) OR (l wang)) yue ;~".
• Adding a wildcard symbol may retrieve word variants: zhang yan yang yun cost sharing ((a wang) OR (l wang)) yue ;*.
