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

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