Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing risk » sharing best, during risk
chen hao » cheng han
hao ying » gao ying, shao ting, chao hing
ying eu » ying zhu, using eu, ying hua
eu cost » au costa, der cost, end cost
how shu » how shih, how slum
how she » how some, how safe, how shih

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "chen hao ying eu cost sharing risk ((how shu) OR (how she)) ;~".
• Adding a wildcard symbol may retrieve word variants: chen hao ying eu cost sharing risk ((how shu) OR (how she)) ;*.
