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
dong yang » dong hoang, wang yang, dan yang
yang yang » wang yang, wang yan
wang yong » wang yang, wang hyoung, wang yan
a credit » bad credit
longer a » longer _
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: ((dong yang) OR (((yang yang) OR (wang yong)))) ya a credit rising costs longer a ;~.
• Adding a wildcard symbol may retrieve word variants: ((dong yang) or (((yang yang) or (wang yong)))) ya a credit rising costs longer a ;*.
