Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing tan » sharing tags, sharing a, sharing bad
wang qian » wang qiao, wang qin, wang liang
wang hui » wang zhi, wang wei, wang he
hong shu » cong shu, tong shui, wong shiu
hong ghi » zhong zhi, hong g, hong hai

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 qian ((wang hui) OR (wang hua)) cost sharing tan ((hong shu) OR (hong ghi)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang qian ((wang hui) OR (wang hua)) cost sharing tan ((hong shu) or (hong ghi)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang qian ((wang hui) OR (wang hua)) cost sharing tan ((hong shu) or (hong ghi)) ;*.
