Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing tan » sharing tags, sharing a, sharing bad
wong shiu » wong siu, song shin, wong sau
yan yang » yang yang, yao yang, dan yang
wong yue » wang yue, hong yu
wan yan » nan yan, wai yan, wang yang
yang yi » yang di, yang xi, yang jui
yi cost » ii cost, di costo, die cost

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: wan yan yang yi cost sharing tan ((((wong shiu) OR (cong shu))) OR (((wong yue) OR (wang yan)))) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wan yan yang yi cost sharing tan ((((wong shiu) OR (cong shu))) or (((wong yue) or (wang yan)))) ;~".
• Adding a wildcard symbol may retrieve word variants: wan yan yang yi cost sharing tan ((((wong shiu) OR (cong shu))) or (((wong yue) or (wang yan)))) ;*.
