Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
zhang ying » zhang ming, zhang jing, zhang ping
zhang ting » zhang ming, zhang jing, zhang ping
bust how » bus how, trust how, out how
just how » just hot, just low, trust how
eu cost » au costa, der cost, end 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: cheng ((zhang ying) OR (zhang ting)) eu cost sharing ((bust how) OR (just how)) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cheng ((zhang ying) or (zhang ting)) eu cost sharing ((bust how) OR (just how)) shu ;~".
• Adding a wildcard symbol may retrieve word variants: cheng ((zhang ying) or (zhang ting)) eu cost sharing ((bust how) OR (just how)) shu ;*.
