Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing risk » sharing best, during risk
wang liang » wang yang
among shu » cong shu, among eu, among sex
yang jun » pang jun, yang jin, yang judy
yang jui » yang judy, yang di, yang yi
yang xi » yang di, yang yi

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