Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing min » sharing oil, sharing mining, sharing risk
dana yaa » nana yaa
hua cost » a cost, up cost, run cost
min hong » tin hong, minh cong, min jeong
hong ghi » hong g, hong hai
nan ya » nana yaa

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: dong ((nan ya) OR (dana yaa)) hua cost sharing min hong ghi ;~.
• Adding a wildcard symbol may retrieve word variants: dong ((nan ya) or (dana yaa)) hua cost sharing min hong ghi ;*.
