Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
wang wang » wang liang, wang yan, wang yong
wang yang » wang yan, wang liang, wang yanling
hua cost » a cost, eu cost, run cost
jin ying » li ying
tan kong » tan hong
yan hua » tan hua, ya hua, wang hua

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 wang) OR (wang yang)) yan hua cost sharing ((jin ying) OR (tan kong)) (sar OR saur) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang wang) OR (wang yang)) yan hua cost sharing ((jin ying) or (tan kong)) (sar or saur) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang wang) OR (wang yang)) yan hua cost sharing ((jin ying) or (tan kong)) (sar or saur) ;*.
