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
tong shui » tong hui, cong shu
jun cost » run cost, can cost, eu cost
gong hui » tong hui, wang hui, gong si

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 ((tong shui) OR (gong hui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((liang yang) or (yang yang)) jun cost sharing risk ((tong shui) OR (gong hui)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((liang yang) or (yang yang)) jun cost sharing risk ((tong shui) OR (gong hui)) ;*.
