Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing a » sharing _
yan yang » yang yang, yao yang, tan yang
dan yang » daun yang, tan yang, wang yang
yun cost » run cost, can cost, eu cost
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) OR (dan yang)) yun cost sharing a wong yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhang ((yan yang) OR (dan yang)) yun cost sharing a wong yue ;*".
