Perhaps you should try some spelling variations:
sharing gains » sharing savings, learning gains, securing gains
cost sharing » risk sharing, cost savings
wang liang » wang yang
hoang seo » hoang sy
liang ii » liang li, liang wei, liang zhi
ii cost » ii cos, ii cross, di costo
hong » long

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 liang) OR (wang yan)) liang ii cost sharing gains ((hoang seo) OR (hong seo)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (wang yan)) liang ii cost sharing gains ((hoang seo) OR (hong seo)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (wang yan)) liang ii cost sharing gains ((hoang seo) OR (hong seo)) ;*.
