Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing hoi » sharing how, sharing hold, sharing home
hua cost » a cost, eu cost, run cost
hoi ying » li ying
ying shu » ying zhu, cong shu, ying hua
yang yi » yang di, yang xi, yang jui
wong yi » weng yi, wong y, wong lai

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 ((yang yi) OR (wong yi)) hua cost sharing hoi ying shu ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((yang yi) or (wong yi)) hua cost sharing hoi ying shu ;*.
