Perhaps you should try some spelling variations:
sharing risk » sharing best, during risk
zhang ying » zhang ming, zhang jing, zhang ting
zhang ping » zhang ming, zhang jing, zhang ting
co sharing » co shaping, cost sharing, car sharing
how she » how some, how safe, how shih
end co » und co, end cost
zhen » zheng, when, chen

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: zhen ((zhang ying) OR (zhang ping)) end co sharing risk how she ;~.
• Adding a wildcard symbol may retrieve word variants: zhen ((zhang ying) or (zhang ping)) end co sharing risk how she ;*.
