Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing risk » sharing best, during risk
liang yang » liang ying, wang yang, huang yang
yang yang » wang yang, wang yan
jun cost » run cost, can cost, eu cost
among eu » among men, among _
among 15 » among _

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

• If you are trying to use Boolean operators, they must be ALL CAPS: wang ((liang yang) OR (yang yang)) jun cost sharing risk ((among eu) OR (among 15)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((liang yang) OR (yang yang)) jun cost sharing risk ((among eu) or (among 15)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((liang yang) OR (yang yang)) jun cost sharing risk ((among eu) or (among 15)) ;*.
