Perhaps you should try some spelling variations:
sharing risk » sharing best, during risk
cost sharing » risk sharing, cost savings
ying hua » ming hua, wang hua, dong hua
how shih » how six
chen mo » chen co, chen hao, chen loo
ying eu » using eu
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: chen mo ((ying eu) OR (((ying hua) OR (ying zhu)))) cost sharing risk ((how she) OR (how shih)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "chen mo ((ying eu) or (((ying hua) OR (ying zhu)))) cost sharing risk ((how she) or (how shih)) ;~".
• Adding a wildcard symbol may retrieve word variants: chen mo ((ying eu) or (((ying hua) OR (ying zhu)))) cost sharing risk ((how she) or (how shih)) ;*.
