Perhaps you should try some spelling variations:
sharing risk » sharing best, during risk
cost sharing » risk sharing, cost savings
zhang ping » zhang ming, zhang jing, zhang ying
zhang ting » zhang ming, zhang jing, zhang ying
risk cong » risk coping, risk among, risk along
yu cost » eu cost, au costa, run cost

You may be able to get more results by adjusting your search query.

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