Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing risk » sharing best, during risk
wang liang » wang yang
risk hong » risk among, risk along, risk how
yang can » yang fan, yang dean, yang yang
can cost » can costa, can lost, can post
hong shu » cong shu, tong shui, wong shiu

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 yanling)) yang can cost sharing risk hong shu ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (wang yanling)) yang can cost sharing risk hong shu ;*.
