Perhaps you should try some spelling variations:
during risk » using risk, during crises, during crisis
liang sun » liang dan, liang tan
risk yang » risk young, risk anp
wing ian » wing tan, twinn ian
wing sun » cong sun, nina sun, wing nut
eun risk » sun risk, can risk, yan risk
own risk » can risk, own list, sun risk
yang shu » cong shu, tan shu, yang du

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 ian) OR (((wing sun) OR (liang sun)))) yi ((eun risk) OR (own risk)) during risk yang shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wing ian) or (((wing sun) or (liang sun)))) yi ((eun risk) OR (own risk)) during risk yang shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wing ian) or (((wing sun) or (liang sun)))) yi ((eun risk) OR (own risk)) during risk yang shu ;*.
