Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing risk » sharing best, during risk
zhang ying » zhang ming, zhang jing, zhang ping
how shih » how six, how she
ying eu » ying zhu, using eu, ying hua
eu cost » au costa, der cost, end cost
how shu » how she, how slum
zhen » zheng, when, chen

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: "zhen zhang ying eu cost sharing risk ((how shu) OR (how shih)) ;~".
• Adding a wildcard symbol may retrieve word variants: zhen zhang ying eu cost sharing risk ((how shu) OR (how shih)) ;*.
