Perhaps you should try some spelling variations:
taking cost » trading cost, taking east, taking root
risk taking » risk sharing
zhong zhi » zhang zhi, hong ghi
zhong tai » hong tan, hong hai
dann bin » dong bin
ye a » yet a, e a, me a
y a » y la
wang » wing, wan, lang

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: ((wang yan) OR (dann bin)) ((ye a) OR (y a)) risk taking cost ((zhong zhi) OR (zhong tai)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang yan) or (dann bin)) ((ye a) or (y a)) risk taking cost ((zhong zhi) OR (zhong tai)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang yan) or (dann bin)) ((ye a) or (y a)) risk taking cost ((zhong zhi) OR (zhong tai)) ;*.
