Perhaps you should try some spelling variations:
costs savings » cost savings, postal savings
savings risk » ratings risk, savings cross, savings rate
yang jui » yang judy, yang di, yang xi
how shih » how six
yang up » tying up, yang jun, hang ups
how she » how some, how safe
wang » wing, wan, lang

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 yanling ((yang up) OR (yang jui)) costs savings risk ((how she) OR (how shih)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yanling ((yang up) or (yang jui)) costs savings risk ((how she) OR (how shih)) ;~".
• Adding a wildcard symbol may retrieve word variants: wang yanling ((yang up) or (yang jui)) costs savings risk ((how she) OR (how shih)) ;*.
