Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing risk » sharing best, during risk
wang zheng » tang zheng, fang sheng, fang zhen
wang liang » wang yang
among shu » cong shu, among eu, among sex
ping ku » ping ke, ping yu
ku cost » eu cost, au costa, run cost

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