Perhaps you should try some spelling variations:
during risk » using risk, during crises, during crisis
tong shui » tong hui, cong shu, gong hui
yang jui » yang judy, yang di, yang yi
end when » mind when
hong shu » cong shu, wong shiu, hong seo
yang xi » yang di, yang yi
end en » end er

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 ((yang xi) OR (yang jui)) ((end en) OR (end when)) during risk ((hong shu) OR (tong shui)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((yang xi) or (yang jui)) ((end en) OR (end when)) during risk ((hong shu) or (tong shui)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((yang xi) or (yang jui)) ((end en) OR (end when)) during risk ((hong shu) or (tong shui)) ;*.
