Perhaps you should try some spelling variations:
during crisis » during crises, housing crisis
during risk » using risk, during crises, reducing risk
wang dan » wang yan, wang ban, wang yidan
dan ying » dan qing, dan yang, fan ying
can lose » can close, can lost, can losers
can cash » a cash
yang shu » cong shu, tan shu, yang du

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 dan ying ((can lose) OR (can cash)) ((during risk) OR (during crisis)) yang shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang dan ying ((can lose) or (can cash)) ((during risk) OR (during crisis)) yang shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang dan ying ((can lose) or (can cash)) ((during risk) OR (during crisis)) yang shu ;*.
