Perhaps you should try some spelling variations:
during risk » using risk, during crises, during crisis
risk yang » risk young, risk anp
wang ban » wang dan, wang yang, bang bang
can lost » can cost, can lose, can post
von carl » von karl
yang shu » cong shu, tan shu, yang du
cash » case

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 ban) OR (wang yan)) yi ((can lost) OR (((do cash) OR (von carl)))) during risk yang shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang ban) OR (wang yan)) yi ((can lost) or (((do cash) or (von carl)))) during risk yang shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang ban) OR (wang yan)) yi ((can lost) or (((do cash) or (von carl)))) during risk yang shu ;*.
