Perhaps you should try some spelling variations:
cost during » boost during, crust during, west during
during risk » using risk, during crises, during crisis
wang yang » wang liang, wang yanling
ying land » lying lands, kong land, ying bank
land cost » land costs, land code, end cost
how she » how some, how safe, how shih

You may be able to get more results by adjusting your search query.

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