Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
wang wang » wang yang, wang liang, wang yan
wang ying » wang yang, wang yong, wang jing
ying hua » ming hua, wang hua, ying zhu
hua cost » a cost, eu cost, run cost
tan wong » tan hong, tan yong, t.j wong
tan kong » tan hong

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: "wang wang ying hua cost sharing ((tan wong) OR (tan kong)) yue ;~".
• Adding a wildcard symbol may retrieve word variants: wang wang ying hua cost sharing ((tan wong) OR (tan kong)) yue ;*.
