Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing risk » sharing best, during risk
wang liang » wang yang
liang yang » liang ying, wang yang, yang yang
yang jui » yang judy, yang di, yang xi
jui cost » eu cost, ii cost, run cost
wong siu » wong shiu, kong siu, wong sau
wong sam » wong sau, wong lai, kong sar

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 yang jui cost sharing risk ((wong siu) OR (wong sam)) ;~.
• Adding a wildcard symbol may retrieve word variants: wang liang yang jui cost sharing risk ((wong siu) or (wong sam)) ;*.
