Perhaps you should try some spelling variations:
during risk » during crises, during crisis, reducing risk
using risk » using rs, funding risk, rising risks
wang dan » wang yan, wang ban, wang yidan
dan yang » daun yang, tan yang, wang yang
yang end » yang anda, yang mind, yang d
end west » und west, end cost, end less

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 dan yang end west ((during risk) OR (using risk)) cong shu ;~".
• Adding a wildcard symbol may retrieve word variants: wang dan yang end west ((during risk) OR (using risk)) cong shu ;*.
