Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing tan » sharing tags, sharing a, sharing bad
yan long » yan cong, van long, pain long
run cost » iran cost, can cost, run cash
hong arm » long arm
hong a » hong ma, hong w, kong a
wang » wing, wan, lang

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan long run cost sharing tan ((hong arm) OR (hong a)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan long run cost sharing tan ((hong arm) OR (hong a)) ;*.
