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 » wang yang, yang yang, huang yang
liang ying » liang liying, huang ying, zhang ying
work shiu » wong shiu, work six

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((liang yang) OR (liang ying)) dean credit during risk work shiu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((liang yang) OR (liang ying)) dean credit during risk work shiu ;*.
