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
end close » und closed
end cost » land cost, end iot
how shu » how she, how shih, how slum
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 cost) OR (end close)) sharing risk how shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "zhen ((zhang ying) OR (zhang ping)) ((end cost) or (end close)) sharing risk how shu ;~".
• Adding a wildcard symbol may retrieve word variants: zhen ((zhang ying) OR (zhang ping)) ((end cost) or (end close)) sharing risk how shu ;*.
