Perhaps you should try some spelling variations:
test during » west during, trust during, test using
during risk » using risk, during crises, during crisis
yang mind » yang cindy, yang jin, sang minh
risk cong » risk coping, risk among, risk along
yang end » yang anda
yang d » yang di, yang du, yang _
wang » wing, wan, lang

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 yan ((((yang end) OR (yang d))) OR (yang mind)) test during risk cong shu ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "wang yan ((((yang end) OR (yang d))) or (yang mind)) test during risk cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang yan ((((yang end) OR (yang d))) or (yang mind)) test during risk cong shu ;*.
