Perhaps you should try some spelling variations:
boost during » roosts during, books during, boom during
cost during » crust during, west during, roosts during
wang liang » wang yang
liang yang » liang ying, wang yang, yang yang
yang mind » yang cindy, yang jin, sang minh
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 yang mind ((cost during) OR (boost during)) risk cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang liang yang mind ((cost during) OR (boost during)) risk cong shu ;*.
