Perhaps you should try some spelling variations:
loss sharing » cost sharing, risk sharing, loss making
zhang ying » zhang ming, zhang jing, zhang ting
zhang ping » zhang ming, zhang jing, zhang ting
best how » test how, west how, lost how
bust how » bus how, just how, trust how
au loss » a loss, ac loss

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 ping)) au loss sharing ((best how) OR (bust how)) shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "cheng ((zhang ying) or (zhang ping)) au loss sharing ((best how) OR (bust how)) shu ;~".
• Adding a wildcard symbol may retrieve word variants: cheng ((zhang ying) or (zhang ping)) au loss sharing ((best how) OR (bust how)) shu ;*.
