Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
cheng han » chen hao
han ying » fan ying, ran ying, tan ying
ying hua » ming hua, wang hua, ying zhu
hua cost » a cost, eu cost, run cost
how shih » how six
how shu » how slum
how she » how some, how safe

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: cheng han ying hua cost sharing best ((((how shu) OR (how she))) OR (how shih)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cheng han ying hua cost sharing best ((((how shu) OR (how she))) or (how shih)) ;~".
• Adding a wildcard symbol may retrieve word variants: cheng han ying hua cost sharing best ((((how shu) OR (how she))) or (how shih)) ;*.
