Perhaps you should try some spelling variations:
sharing risk » sharing best, during risk
sharing his » sharing big, sharing dps, sharing how
wang yao » wang yan, yang yao, wang tao
gang yao » yang yao, wang yan, ganga ya
yang hua » wang hua, yang hui, ying hua
hua cost » a cost, eu cost, run cost
son shu » cong shu

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 yao) OR (gang yao)) yang hua cost ((sharing his) OR (sharing risk)) son shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yao) or (gang yao)) yang hua cost ((sharing his) OR (sharing risk)) son shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yao) or (gang yao)) yang hua cost ((sharing his) OR (sharing risk)) son shu ;*.
