Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing a » sharing _
fan yang » dan yang, fan ying, tan yang
yang yun » yang jun, tang yun, yang yue
yun cost » run cost, can cost, eu cost
wang yue » wong yue, wang hua, wang he
yang » ryang
yan » ryan

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