Perhaps you should try some spelling variations:
spring costs » firing costs, shipping costs, firing cost
bank spring » bank working, bank savings, banks during
costs cost » costs cross, costs case, costs cash
wang yang » wang yan, wang liang, wang yanling
yang jui » yang judy, yang di, yang yi
yang xi » yang di, yang yi

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 ((yang xi) OR (yang jui)) non bank spring costs cost ;~.
• Adding a wildcard symbol may retrieve word variants: wang yang ((yang xi) or (yang jui)) non bank spring costs cost ;*.
