Perhaps you should try some spelling variations:
cost during » boost during, crust during, west during
risk along » risk among, ask along
wang yang » wang yan, wang liang, wang yanling
yang yang » wang yan
yang mind » yang cindy, yang jin, sang minh
mind cost » wind costs, end cost, land cost
risk cong » risk coping, risk among, risk cost

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