Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
wang liang » wang yang
liang ying » liang liying, huang ying, zhang ying
ying hua » ming hua, wang hua, ying zhu
hua cost » a cost, eu cost, run cost
tan wong » tan hong, tan yong, tan eng
tan kong » tan hong

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 ying hua cost sharing ((((tan wong) OR (t.j wong))) OR (tan kong)) yue ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang liang ying hua cost sharing ((((tan wong) OR (t.j wong))) or (tan kong)) yue ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang ying hua cost sharing ((((tan wong) OR (t.j wong))) or (tan kong)) yue ;*.
