Perhaps you should try some spelling variations:
during crisis » during crises, housing crisis
during risk » using risk, during crises, reducing risk
work shiu » work six
wong shiu » wong siu, cong shu, song shin
yan yang » yang yang, yao yang, dan yang
wang » wing, wan, lang
dean » dewan, jean, den

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 yan yang dean exit ((during risk) OR (during crisis)) ((work shiu) OR (wong shiu)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan yang dean exit ((during risk) or (during crisis)) ((work shiu) OR (wong shiu)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan yang dean exit ((during risk) or (during crisis)) ((work shiu) OR (wong shiu)) ;*.
