Perhaps you should try some spelling variations:
credit during » credit scoring, credit rating, exit during
dean credit » clean credit, deals credit, de credit
during risk » using risk, during crises, during crisis
liang yang » liang ying, yang yang, huang yang
zhang ying » zhang ming, zhang jing, zhang ping
wang yang » wang yan, wang liang, wang yanling
work shiu » wong shiu, work six

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 ((((liang yang) OR (wang yang))) OR (zhang ying)) dean credit during risk work shiu ;~.
• Adding a wildcard symbol may retrieve word variants: wang ((((liang yang) or (wang yang))) or (zhang ying)) dean credit during risk work shiu ;*.
