Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing risk » sharing best, during risk
wang yang » wang yan, wang yanling
risk tong » risk among, risk along
yang jun » yang jui, pang jun, yang jin
ying jin » yang jin, jing ji, yang jie
tong hui » wang hui

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