Perhaps you should try some spelling variations:
during crisis » during crises, housing crisis
risk during » risks during, risk using, crisis during
crisis yang » crisis kang, crisis bank, crisis can
can risk » chain risk
yang shu » cong shu, tan shu, yang du
yang xi » yang di, yang yi, yang jui
yan yi » yang yi, tan yi, yan zi

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