Perhaps you should try some spelling variations:
rising risks » growing risks, rising costs, taking risks
funding risk » funding list, building risk, fund risk
yang using » yang jing, making using, change using
wang yang » wang yan, wang liang, wang yanling
au costa » can costa, _ costa, da costa
how shih » how six, how she
eu cost » der cost, end cost, eu court

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 using ((eu cost) OR (au costa)) ((rising risks) OR (funding risk)) how shih ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yang using ((eu cost) OR (au costa)) ((rising risks) or (funding risk)) how shih ;~".
• Adding a wildcard symbol may retrieve word variants: wang yang using ((eu cost) OR (au costa)) ((rising risks) or (funding risk)) how shih ;*.
