Perhaps you should try some spelling variations:
clean credit » loan credit, create credit, green credit
dean credit » deals credit, de credit, des credit
rating risk » ratings risk, trading risk, raising risk
liang yang » liang ying, yang yang, huang yang
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)) ((dean credit) OR (clean credit)) rating risk work shiu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang ((liang yang) or (wang yang)) ((dean credit) OR (clean credit)) rating risk work shiu ;~".
• Adding a wildcard symbol may retrieve word variants: wang ((liang yang) or (wang yang)) ((dean credit) OR (clean credit)) rating risk work shiu ;*.
