Perhaps you should try some spelling variations:
during risk » during crises, during crisis, reducing risk
using risk » using rs, funding risk, rising risks
wang yang » wang yan, wang liang, wang yanling
yang ying » yang yang, yang jing, huang ying
fund risk » bond risk, funding risk
au costa » can costa, _ costa, da costa
how shih » how six, how she
ying au » ying zhu, ying hua

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 ying au costa ((((during risk) OR (using risk))) OR (fund risk)) how shih ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang ying au costa ((((during risk) or (using risk))) or (fund risk)) how shih ;*.
