Perhaps you should try some spelling variations:
cost sharing » risk sharing, cost savings
sharing risk » sharing best, during risk
zhang ying » zhang jing, zhang ping, zhang ting
zhang ming » zhang xin
end cost » end close, land cost, end iot
how shih » how six, how she
zhen » zheng, when, chen

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: "zhen ((zhang ying) OR (zhang ming)) end cost sharing risk how shih ;~".
• Adding a wildcard symbol may retrieve word variants: zhen ((zhang ying) OR (zhang ming)) end cost sharing risk how shih ;*.
