Perhaps you should try some spelling variations:
during risk » using risk, during crises, during crisis
cost during » boost during, crust during, west during
wang yang » wang yan, wang yanling
ying jun » yang jun, ying jin, yang jui
jun cost » run cost, can cost, eu cost
how some » how women
how she » how safe, how shih

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 liang) OR (wang yang)) ying jun cost during risk ((how she) OR (how some)) ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) OR (wang yang)) ying jun cost during risk ((how she) or (how some)) ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) OR (wang yang)) ying jun cost during risk ((how she) or (how some)) ;*.
