Perhaps you should try some spelling variations:
during crisis » during crises, housing crisis
during risk » using risk, during crises, reducing risk
huang yang » huang ying, huang chang, wang yang
yang jing » wang jing, yang jin, huang jing
can trust » al trust
how she » how some, how safe, how shih

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 ((huang yang) OR (yang jing)) can trust ((during risk) OR (during crisis)) how she ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((huang yang) or (yang jing)) can trust ((during risk) OR (during crisis)) how she ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((huang yang) or (yang jing)) can trust ((during risk) OR (during crisis)) how she ;*.
