Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing tan » sharing tags, sharing a, sharing bad
qian wang » yiqian wang, qian rong, qian yan
yang yang » wang yang, wang yan
hua cost » a cost, eu cost, run cost
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 ((((qian wang) OR (yang yang))) OR (yao yang)) hua cost sharing tan hong shu ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((((qian wang) or (yang yang))) or (yao yang)) hua cost sharing tan hong shu ;*.
