Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing risk » sharing best, during risk
dong sink » dong bin, dong ping
risk hong » risk among, risk along, risk how
dong cao » dong xiao, dan cao, dong nan
hua cost » a cost, eu cost, run cost
hong hai » shang hai, zhong tai, dang hai
sink » signk, sindk, skink
sin » sign, sind, skin

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 cao) OR (((dong sink) OR (dong sin)))) ya hua cost sharing risk hong hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((dong cao) or (((dong sink) OR (dong sin)))) ya hua cost sharing risk hong hai ;~".
• Adding a wildcard symbol may retrieve word variants: ((dong cao) or (((dong sink) OR (dong sin)))) ya hua cost sharing risk hong hai ;*.
