Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing a » sharing _
wong shiu » wong siu, cong shu, song shin
yan yang » yang yang, dan yang, tan yang
yao yang » yang yang
hong hai » shang hai, zhong tai, dang hai
xi cost » ii cost, di costo, die cost
wang » lang

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: ((wang OR wing) OR wan) ((yan yang) OR (yao yang)) xi cost sharing a ((wong shiu) OR (hong hai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang or wing) or wan) ((yan yang) OR (yao yang)) xi cost sharing a ((wong shiu) or (hong hai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang or wing) or wan) ((yan yang) OR (yao yang)) xi cost sharing a ((wong shiu) or (hong hai)) ;*.
