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
yang mind » yang cindy, yang jin, sang minh
mind cost » wind costs, end cost, land cost
risk cong » risk coping, risk among, risk along

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 liang) OR (wang yang)) yang mind cost during risk cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) OR (wang yang)) yang mind cost during risk cong shu ;*.
