Perhaps you should try some spelling variations:
credit rising » credit rating, credit training, credit ratings
rising costs » rising cost, driving costs, firing costs
costs longer » costs along, costs linked, does longer
wang yang » wang yan, wang liang, wang yanling
yang yang » wang yan
wang yong » wang hyoung, wang yan, wang shiyong
longer yu » longer run, longer _, longer a
a credit » bad credit
ya a » a a, y a, ye a

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) OR (((yang yang) OR (wang yong)))) ya a credit rising costs longer yu ;~.
• Adding a wildcard symbol may retrieve word variants: ((wang yang) or (((yang yang) or (wang yong)))) ya a credit rising costs longer yu ;*.
