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
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

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