Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
zhang yang » zhang yan, zhang fang, zhang ying
yang yang » wang yang, wang yan
sharing a » sharing _
yang yue » wang yue, yang yun, yang jui
yue cost » true cost, type cost, use cost
wong yue » wang yue

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: "zhang yang yang yue cost sharing a ((wong yue) OR (hong yu)) ;~".
• Adding a wildcard symbol may retrieve word variants: zhang yang yang yue cost sharing a ((wong yue) OR (hong yu)) ;*.
