Perhaps you should try some spelling variations:
sharing gains » sharing savings, learning gains, securing gains
cost sharing » risk sharing, cost savings
wong shiu » wong siu, cong shu, song shin
yet a » et a, yet _, get a
ya a » a a, y a, ye a
yu a » you a, eu a, u a
dong » doing, long, done

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: ((dong sin) OR (wang yan)) ((((ya a) OR (yu a))) OR (yet a)) cost sharing gains wong shiu ;~.
• Adding a wildcard symbol may retrieve word variants: ((dong sin) or (wang yan)) ((((ya a) or (yu a))) or (yet a)) cost sharing gains wong shiu ;*.
