Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing bad » sharing a, sharing 3d, sharing big
wang yang » wang yan, wang liang, wang yanling
yang fan » zhang fan, yang dean, yang yang
yang jin » yang jie, yang jun, ying jin
wong sam » wong sau, wong lai, kong sar
hong g » hong ng, hong w, hong 7

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 yang ((yang fan) OR (yang jin)) cost sharing bad ((wong sam) OR (hong g)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang ((yang fan) OR (yang jin)) cost sharing bad ((wong sam) or (hong g)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang ((yang fan) OR (yang jin)) cost sharing bad ((wong sam) or (hong g)) ;*.
