Perhaps you should try some spelling variations:
during crisis » during crises, housing crisis
risk during » risks during, risk using, crisis during
can risk » chain risk
yang hui » yang jui, wang hui, yang muxi
yang xi » yang di, yang jui
yang yi » yang di, yang jui
tan shu » than she
yan yi » tan yi, yan zi, yin yi

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 yi) OR (((yang xi) OR (yang yi)))) can risk during crisis ((yang hui) OR (tan shu)) ;~.
• Adding a wildcard symbol may retrieve word variants: wing ((yan yi) or (((yang xi) or (yang yi)))) can risk during crisis ((yang hui) or (tan shu)) ;*.
