Perhaps you should try some spelling variations:
sharing risk » sharing best, during risk
cost sharing » risk sharing, cost savings
zhang ping » zhang ming, zhang ying, zhang xin
zhang ting » zhang ming, zhang ying, zhang xin
zhang jing » zhang ming, zhang jin, zhang ying
risk cong » risk coping, risk among, risk along
zhu cost » eu cost

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 ((((zhang ping) OR (zhang ting))) OR (zhang jing)) zhu cost sharing risk cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((((zhang ping) OR (zhang ting))) or (zhang jing)) zhu cost sharing risk cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((((zhang ping) OR (zhang ting))) or (zhang jing)) zhu cost sharing risk cong shu ;*.
