Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing risk » sharing best, during risk
wong shiu » wong siu, cong shu, song shin
yan yang » yang yang, yao yang, dan yang
yang jui » yang judy, yang di, yang xi
jui cost » eu cost, ii cost, run cost
wong sau » wong sam, wong siu, wong lai
wang » wing, wan, 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 yan yang jui cost sharing risk ((wong shiu) OR (wong sau)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang yan yang jui cost sharing risk ((wong shiu) or (wong sau)) ;*.
