Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
wang yidan » wang yan
sharing a » sharing _
wang dan » wang yan, wang ban, wang yang
yang can » yang fan, yang dean, yang yang
can cost » can costa, can lost, can post
wong sam » wong sau, wong lai, kong sar
hong ng » hong kong, hong jong, hong hong

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 yidan) OR (wang dan)) yang can cost sharing a ((wong sam) OR (hong ng)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yidan) OR (wang dan)) yang can cost sharing a ((wong sam) OR (hong ng)) ;*.
