Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
zhang yan » zhang fan, zhang jian, wang yan
sharing a » sharing _
yang yun » yang jun, tang yun, yang yang
yang yue » wang yue, yang jui, yang yi
wong yue » wang yue, hong yu
a wong » y wong

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

• Performing a fuzzy search may retrieve terms with similar spellings: zhang yan ((yang yun) OR (yang yue)) cost sharing a wong yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang yan ((yang yun) OR (yang yue)) cost sharing a wong yue ;*".
