Perhaps you should try some spelling variations:
sharing risk » sharing best, during risk
dong sink » dong sin, dong bin, dong ping
risk hong » risk among, risk along, risk how
dong cao » dong xiao, dan cao, dong nan
hua cost » eu cost, run cost
hong hai » shang hai, zhong tai, dang hai
up cost » up costs

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