Perhaps you should try some spelling variations:
sharing gains » sharing savings, learning gains, securing gains
rent sharing » risk sharing, rent seeking, cost sharing
yang yang » wang yang, wang yan
yang yao » wang yan, yang yi, yang fan
hua rent » hua ren
yang ka » yang fan
yang xi » yang di, yang yi, yang jui
hong a » hong ma, hong w, kong a

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: ((((((yang ka) OR (yang yao))) OR (yang yang))) OR (yang xi))ng ya hua rent sharing gains hong a ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((((yang ka) OR (yang yao))) or (yang yang))) or (yang xi))ng ya hua rent sharing gains hong a ;~".
• Adding a wildcard symbol may retrieve word variants: ((((((yang ka) OR (yang yao))) or (yang yang))) or (yang xi))ng ya hua rent sharing gains hong a ;*.
