Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing risk » sharing best, during risk
using eu » using e, using ed, using es
ying hua » ming hua, wang hua, ying zhu
ying eu » ying zhu
how she » how some, how safe, how shih
zhen » zheng, when, chen

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

• Performing a fuzzy search may retrieve terms with similar spellings: zhen zhang ((((ying eu) OR (using eu))) or (ying hua)) cost sharing risk how she ;~.
• If you are trying to use Boolean operators, they must be ALL CAPS: zhen zhang ((((ying eu) OR (using eu))) OR (ying hua)) cost sharing risk how she ;*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhen zhang ((((ying eu) OR (using eu))) or (ying hua)) cost sharing risk how she ;*".
